Description

Technical Field

[0001] The present disclosure relates to methods and apparatuses for the installation and removal of catalysts. In particular, the present disclosure relates to an installation tool, method, and system for installing a catalyst in a reaction tube of a tubular reactor. Further, the present disclosure relates to methods and accessories for discharging such a reaction tube in which a catalyst is installed and initially at least partially filled with the catalyst. Further, the present disclosure relates to a catalyst and related components for installation in such a reaction tube.

Background Art

[0002] Conventional so-called fixed-bed tubular reactors typically have a cylindrical shape and include a reactor shell with a plurality of tubes that are usually directly filled with catalyst particles. During use, a heat transfer medium flows outside these tubes through the reactor shell, thereby adjusting the temperature of the catalyst inside the tubes by heat exchange across the entire tube wall. Thus, if the reaction is an exothermic reaction, the heat transfer medium can remove heat from the catalyst, and if the reaction is an endothermic reaction, the heat transfer medium can supply heat to the catalyst.

[0003] In some reactions, the heat effect of the reaction is moderate, so the heat effect of the reaction is not a problem or can be easily managed. In some cases, the heat effect is small enough that large-diameter tubes can be used. This has the advantage of having a large amount of catalyst present inside the tubes.

[0004] However, for more exothermic or endothermic reactions, efficient heat transfer to the heat transfer medium through the tube wall is required to be able to control the conditions inside the reactor, maintain a stable operating temperature, and avoid the occurrence of harmful effects. Such effects can include, in the case of exothermic reactions, side reactions that occur, damage to the catalyst due to sintering of catalytic active sites, etc., and in the worst case, thermal runaway. The harmful effects of endothermic reactions can include quenching of the reaction.

[0005] ​​​​​​​​​​ To achieve the desired efficiency, the surface area of ​​the tube wall per unit length must be maximized. Traditionally, this has been achieved by installing a large number of small-diameter tubes. In some reactions, size limitations mean that the tubes have an inner diameter of only about 15-40 mm. However, the use of this large number of tubes increases the cost and complexity of the reactor.

[0006] Therefore, in an attempt to mitigate these problems, multiple catalysts are configured such that the catalyst is not directly packed into the reaction tube but is instead located inside the reaction tube. Career Alternative approaches have been developed, particularly for more exothermic or endothermic reactions, which are housed within these structures.

[0007] Such catalysts Career The first type is described in International Publication No. 2011 / 048361. This configuration seeks to optimize heat transfer in the tube wall so that larger tubes and larger amounts of smaller catalyst particles can be used for more exothermic or even endothermic reactions. Catalyst described in International Publication No. 2011 / 048361 Career The apparatus includes an annular container for holding the catalyst during use. The container has a perforated inner wall defining the tube, a perforated outer wall, a top surface that closes the annular container, and a bottom surface that closes the annular container. The surface that closes the bottom of the tube is formed by the inner wall of the annular container. A skirt extends upward from the perforated outer wall of the annular container from the bottom surface or near the bottom surface of the container to a position below the location of the seal. A seal is located on the top surface or near the top surface and extends from the container by a distance that extends beyond the outer surface of the skirt.

[0008] Such catalysts Career The second type is described in International Publication No. 2012 / 136971. In this configuration, the catalyst CareerThe present invention relates to a container for holding a monolithic catalyst during use, wherein the container has a bottom surface that closes the container and a skirt that extends upward from the bottom surface of the container to a position below the location of the seal and separated from the seal, and the skirt is positioned such that there is a space between the outer surface of the monolithic catalyst and the skirt, and a seal that is located on or near the upper surface of the monolithic catalyst and extends from the monolithic catalyst by a distance that extends beyond the outer surface of the skirt.

[0009] Such catalysts Career The third type is described in International Publication No. 2016 / 050520. In this configuration, the catalyst Career It includes a container for holding the catalyst during use. The container has a bottom surface and a top surface that close the container. Career The exterior wall extends from the bottom to the top, and the seal is, Career It extends from the container by the distance that extends beyond the outer wall. Career The exterior wall has an opening located below the seal.

[0010] The method, tools, and system are suitable for insertion into reaction tubes within tubular reactors and any catalyst. Career It can be applied to this.

[0011] A tubular reactor contains hundreds or, in some cases, thousands of such catalysts. Career Furthermore, catalysts may be present, and therefore, rapid and efficient loading is important for the user. Career And for optimal reactor performance, loading is performed on the catalyst in the reaction tube. Career Proper alignment of the catalyst should be ensured. In heat exchange tubular reactors, the catalyst should be positioned so as to prevent uncontrolled heating or cooling. Career It is also desirable to place it in the heat exchange zone. Furthermore, if necessary, the catalyst from the reaction tube Career It is desirable to establish equipment and methods suitable for the discharge of [the substance].

[0012] The purpose of this disclosure is to provide catalysts that address these issues. Career The objective is to provide an apparatus and method for loading and unloading.

Summary of the Invention

[0013] In a first aspect of the present disclosure, a method of installing a catalyst in a first selected reaction tube of a tubular reactor, Career comprising: i) preparing an installation tool, the installation tool comprising a) an installation frame and b) a movable ram mounted on the installation frame and configured to push one or more catalysts into the first selected reaction tube, and Career c) one or more anchors for releasably attaching the installation frame to the tubular reactor, and ii) attaching the installation tool to the tubular reactor by engaging one or more anchors with one or more reaction tubes positioned along the first selected reaction tube to align the movable ram with the first selected reaction tube, and iii) operating the movable ram to push one or more catalysts into the first selected reaction tube. Career A method including these steps is provided.

[0014] Career In a second aspect, the present disclosure provides an installation tool for installing a catalyst in a selected reaction tube of a tubular reactor, the installation tool comprising a) an installation frame and b) a movable ram mounted on the installation frame and configured to push one or more catalysts into the selected reaction tube, and Career c) one or more anchors for engaging one or more reaction tubes positioned along the selected reaction tube to releasably attach the installation frame to the tubular reactor. An installation tool including these components is provided.

[0015] Career In a third aspect, the present disclosure provides an installation system for installing a catalyst in a reaction tube of a tubular reactor, the installation system comprising Career ​Provided in a second aspect, an installation tool configured to be installed in a headspace or a footer space of a tubular reactor; A power source that can be arranged outside the tubular reactor and is configured to move a movable ram of the installation tool; One or more hoses for supplying power from the power source to the installation tool; An installation system comprising the above is provided.

[0016] The method and system can be applied to any catalyst adapted to be inserted into a tubular reactor. Career It can be applied to.

[0017] In some embodiments, the power source may alternatively be arranged inside the tubular reactor.

[0018] Preferably, the installation tool can facilitate the loading of the catalyst into the reaction tube of the tubular reactor. The installation tool can facilitate the correct alignment of the catalyst during loading. In particular, the engagement of one or more anchors can improve the alignment between the movable ram and the selected reaction tube. Advantageously, the engagement of one or more anchors in one or more reaction tubes along the first selected reaction tube can avoid the need for any part of the fixing system to be in or extend within the first selected reaction tube. This can result in a simpler and faster loading method. Career During loading. Career Correct alignment can be facilitated.

[0019] One or more reaction tubes along the first selected reaction tube may be one or more reaction tubes directly adjacent to the first selected reaction tube, or one or more reaction tubes near the first selected reaction tube.

[0020] In step ii) of the method of the first embodiment, the installation tool can be mounted such that the installation frame is located in the headspace or footer space of the tubular reactor outside the reaction tube. The installation frame may be located above the upper tube sheet of the tubular reactor or below the lower tube sheet of the tubular reactor. In the case of a vertically oriented tubular reactor, the catalyst is located from the top end of the tubular reactor. Career It is generally preferable to load the following. As a result, in some preferred embodiments, the installation tool may be located above the upper tube sheet in the headspace of a vertically oriented tubular reactor.

[0021] Preferably, the installation tool can be sized to fit into the headspace or footer space of the tubular reactor. Step i) of the method of the first embodiment may further include inserting the installation tool into the headspace or footer space of the tubular reactor through the access opening of the tubular reactor.

[0022] Preferably, the installation tool can be sized to accommodate the movement of the installation frame into and out of the headspace or footer space. This allows for the complete removal of the installation tool from the tubular reactor after loading is complete, which means there is no need for any parts to remain in the operating tubular reactor that could obstruct the flow of gases in and out of the reaction tubes.

[0023] The movable ram may be electrically powered or manually driven. The movable ram may be switchable between an electrically powered mode in which the movable ram moves under electric power and a manually driven mode in which the movable ram is manually driven. The movable ram may be hydraulic, pneumatic, or electromechanical.

[0024] Preferably, the electric ram is catalytically increased and consistent insertion force. Career Providing power to the ram can improve its operating efficiency. However, in some situations, it may be preferable to use a manually driven ram or to manually drive a normally powered ram.

[0025] In some embodiments, the installation tool may be coupled to a power source for moving a movable ram, which may be located outside the tubular reactor. Positioning the power source outside the tubular reactor is advantageous when internal space is limited. The power source can be a hydraulic, pneumatic, or electric source. For example, in some embodiments, the power source may be a hydraulic source coupled to the installation tool by one or more hydraulic hoses that can extend through the access opening of the tubular reactor. This configuration allows for the use of a larger hydraulic source (which cannot fit through the access opening) and also reduces the size of the installation tool.

[0026] In some other embodiments, the installation tool may include a power source located inside the tubular reactor to move the movable ram. In such cases, the power source may be a hydraulic source, a pneumatic source, or a power supply. For example, in some embodiments, the power source may be a power supply, such as an electric motor mounted directly to the installation frame.

[0027] In step iii) of the method of the first embodiment, one, two, three or more catalysts Career The insertion set may be pushed into the first selected reaction tube by a single stroke of the movable ram. Step iii) of the method of the first embodiment may be repeated one or more times to push one or more further insertion sets into the first selected reaction tube.

[0028] The mounting frame holds one or more catalysts. Career A loading station can be defined for receiving the catalyst. The loading station may have one, two, three, or more catalysts. Career The movable ram may be configured to hold the insertion set of the catalyst Career The insertion set may be configured to be pushed into the first selected reaction tube in a single stroke.

[0029] Preferably, a catalyst CareerForming the insertion set into an insertion set can improve operational efficiency by shortening the loading time of the installation tool, especially when the insertion set is pre-formed. In addition, the insertion set contains the catalyst within the set. Career Maintaining relative alignment between components can also help reduce the possibility of misalignment during insertion into the reaction tube.

[0030] By pushing the insertion set into the first end of the first selected reaction tube, one or more catalysts are inserted. Career The catalyst can be pushed out from the second end of the first selected reaction tube. For example, the installation tool first pushes out the catalyst. Career When used in a reaction tube filled with a catalyst, Career By pushing the first end, the catalyst Career The catalyst in the reaction tube can be discharged from the second end. Career It can be efficiently replaced. First, all catalysts in the reaction tube can be replaced. Career This can be replaced in this way (for example, if a complete refresh of the catalyst in the reaction tube is desired). Alternatively, the catalyst at the second end. Career Only a few of these may be replaced in this manner (for example, if replacement of the initial boiler in the reaction tube is desired, for example, due to catalyst poisoning). The second end may be the lower end or the upper end of the tubular reactor.

[0031] The method of the first embodiment may further include removing from the installation tool one or more anchors that are not aligned with the reaction tube when the movable ram is aligned with the first selected reaction tube. To facilitate this, one or more anchors may be removable from the installation tool.

[0032] When loading several reaction tubes, particularly those around or near a tubular reactor, the reaction tubes may not always be positioned directly beneath each anchor of the installation tool. In such cases, the anchors may be removed from the installation frame. For example, in an installation tool with four anchors, one, two, or three anchors may be removed. The anchors remaining attached to the installation frame can be used to secure the installation tool.

[0033] The method of the first embodiment may further include stabilizing the installation tool using one or more stabilizing legs coupled to the installation frame.

[0034] Stabilizing legs can function to provide stability to the installation tool, for example, to reduce or prevent swinging, tilting, or inclination of the installation frame during use. Each stabilizing leg may comprise, for example, height-adjustable screws, legs, pads, plates, etc. Each stabilizing leg may be configured to directly or indirectly contact the tube sheet between reaction tubes by having dimensions small enough to fit between reaction tubes, for example. Alternatively, each stabilizing leg may be configured to extend across one or more reaction tubes by having, for example, a footplate.

[0035] Stabilizing legs may be used in conjunction with anchors. For example, each anchor may have an associated stabilizing leg. Stabilizing legs may be provided on or near the anchor. For example, if the installation tool has a substantially quadrilateral basic shape, each corner may be provided with an anchor and a stabilizing leg. Stabilizing legs may be engaged by footplates against the protruding surfaces of the tube sheet and / or reaction tubes before or after engaging with the anchor to reduce or eliminate lifting or tilting of the installation frame while the anchor is being fixed.

[0036] The method of the first embodiment may further include leveling the installation tool by adjusting one or more stabilizing legs.

[0037] Preferably, stabilizing legs may be used to ensure that the longitudinal (e.g., vertical) axis of the movable ram is aligned with the longitudinal axis of the reaction tube.

[0038] One or more stabilizing legs may be used in place of one or more anchors that are removed from the installation tool. As described above, one or more anchors may need to be removed because they do not align with the reaction tube. In such cases, stabilizing legs may be used to level and / or stabilize the installation tool. For example, if the installation tool has a basic shape that is approximately quadrilateral, three corners may be fixed with anchors and one corner may be stabilized with a stabilizing leg, or for example, two corners may be fixed with anchors and two corners may be stabilized with a stabilizing leg, or for example, one corner may be fixed with anchors and three corners may be stabilized with a stabilizing leg.

[0039] One or more anchors may be manually, hydraulically, pneumatically, or electrically extendable. In some other embodiments, one or more anchors may be spring-loaded anchors, optionally equipped with spring-loaded cam devices.

[0040] In step ii) of the method of the first embodiment, each of the one or more anchors may be extended to grip the inner surface of the reaction tube. In some embodiments, one or more anchors can be extended using manual, hydraulic, pneumatic, or electric drive force. The same power source can be used to actuate the anchors and move the movable ram. For example, the same hydraulic source may be connected to both. Alternatively, the anchors may be actuated by a dedicated power source provided on or adjacent to the mounting frame. For example, a manual hydraulic pump may be used.

[0041] In some other embodiments, one or more anchors may be spring-loaded and biased to extend to grip the inner surface of the reaction tube.

[0042] The mounting frame may include multiple anchor mounts for connecting anchors to the mounting frame. The multiple anchor mounts may connect one or more catalysts to the selected reaction tube. Career The mounting frame may surround an opening that allows passage. The mounting frame may comprise, for example, three anchor mounts arranged in a triangular arrangement around the opening, or four anchor mounts arranged in a quadrilateral arrangement around the opening.

[0043] If the installation tool is located within a footer space for mounting to the lower tube sheet, the installation tool may be provided with one or more braces. The braces may span between the installation frame and the contact area of ​​the tubular reactor. For example, the braces may extend from the platform of the installation frame and contact, for example, the floor of the tubular reactor, supporting the installation frame and / or acting to push it up against the lower tube sheet. The braces may be provided with one or more extendable legs coupled to the platform. The extendable legs may be extendable, for example, manually, pneumatically or hydraulically.

[0044] The movable ram is one or more catalysts Career The system may include an alignment device for aligning the catalyst with a first selected reaction tube. The alignment device may include one or more catalysts. Career The alignment device may include a first engaging portion that engages with a second engaging portion. The first engaging portion may be elastic and / or spring-loaded. Preferably, the alignment device has one or more catalysts on the central axis of the first selected reaction tube. Career It is equipped with a centering device for aligning the parts.

[0045] Preferably, the alignment device is used during insertion of the catalyst Career By assisting in alignment, the efficient operation of installation tools can be facilitated. For example, a catalyst Career If they are manually loaded into the installation tool, they may be oriented slightly off-vertical. The alignment device is catalytic at the start of the insertion stroke. CareerIt can capture and vertically align the catalyst. In this way, loading the installation tool allows the operator to use the catalyst during each loading operation. Career Because there is no need to verify the precise alignment, it can be done more quickly.

[0046] The movable ram is one or more catalysts Career The mixture is simultaneously pushed into a second selected reaction tube and, optionally, one or more further selected reaction tubes, and one or more catalysts. Career It may be configured to push into the first selected reaction tube. By acting on the movable ram, one or more catalysts Career The first selected reaction tube is simultaneously pushed in, along with one or more catalysts. Career The mixture is then pushed into the second selected reaction tube, and optionally one or more catalysts are added. Career The catalyst can be forced into one or more further selected reaction tubes. To facilitate this, a movable ram can be used to push one or more catalysts into one or more reaction tubes. Career A first ram section for pushing the first selected reaction tube and one or more catalysts Career It may also include a second ram section for simultaneously pushing the catalyst into a second selected reaction tube, and optionally one or more catalysts. Career It may include one or more additional ram sections for simultaneously pushing into one or more further selected reaction tubes.

[0047] Preferably, the catalyst is loaded by simultaneously loading two, three or more reaction tubes using an installation tool. Career This allows for faster reloading.

[0048] The method of the first embodiment is iv) Disengaging one or more anchors from one or more reaction tubes located along the first selected reaction tube, v) Reattaching the installation tool to the tubular reactor by moving the installation tool by engaging one or more anchors with one or more reaction tubes located along the second selected reaction tube in order to align the movable ram with the second selected reaction tube, vi) Activate the movable ram to activate one or more catalysts Career Push it into the second selected reaction tube, It can further include:

[0049] The stabilizing legs may be repositioned and / or adjusted as necessary for loading the second selected reaction tube.

Career The position may be controlled.

[0083] Multiple catalysts Career The spacer unit may be configured to be installed in the reaction tube using one identical installation tool. The installation tool uses a movable ram to install multiple catalysts. Career The spacer unit can also be pushed into the reaction tube.

[Modes for carrying out the invention]

[0122] Hereinafter, aspects and embodiments of the present disclosure will be described, simply as an example, in relation to a vertically oriented tubular reactor having a plurality of vertical reaction tubes extending between an upper tube sheet and a lower tube sheet. However, it will be understood that the present disclosure may also be applicable to other forms of tubular reactors that may employ other orientations.

[0123] Furthermore, any references to orientation in this specification; for example, terms such as top, bottom, upper, lower, upward, and downward are used in relation to the orientation of a part as shown in the drawings to which they are referred, but should not be considered to limit the potential orientation of such a part in actual use. For example, a part described as being oriented vertically may be oriented horizontally.

The power source 30 may be a hydraulic source, a pneumatic source, or a power supply. In some embodiments, the power source 30 may be a power supply, for example, an electric motor that can be directly mounted to the installation frame 21. However, in other embodiments, the power source 30 may be a hydraulic source, for example, a hydraulic power unit (HPU) 32, a hydraulic power pack, or other hydraulic pump. The HPU 32 may be located outside the housing 2 and connected to the installation tool 20, in particular the movable ram 22, by one or more hoses 31.

[0144] The anchor 23 functions to releasably engage the installation frame 21, and therefore the installation tool 20, with the tubular reactor 1.

[0145] Anchors 23 may be provided at each anchor mount of the installation frame 21. For example, each opening 28 may have an associated anchor 23.

As shown in Figure 8, the reaction tubes 8b may be one or more reaction tubes 8 directly adjacent to the first selected reaction tube 8a, or one or more reaction tubes located near the first selected reaction tube 8a.

[0150] The anchor 23 can be extended using manual, hydraulic, pneumatic, or electric force (e.g., HPU 32). The same power source 30 can be used to actuate the anchor 23 and move the movable ram 22. Alternatively, the anchor 23 may be actuated by a dedicated power source located on or adjacent to the mounting frame 21. For example, a manually operated hydraulic pump may be provided for this function.

[0164] As shown in the exploded view of Figure 10, the catalyst Career 10 can be formed from several individual components that can be assembled together by any suitable means, including welding, for example. In some embodiments, such components may include a perforated inner tube 120, a perforated intermediate tube 121, an outer tube 122, a bottom cap 123, an annular top ring 124, an upper cap 125, and an annular seal ring 126.

[0165] catalyst Career10 may be formed from any suitable material. Such material is generally selected to withstand the operating conditions of the reactor. Generally, catalyst Career It is manufactured from carbon steel, aluminum, stainless steel, other alloys, or any material that can withstand the reaction conditions.

[0166] The appropriate thickness of the components is approximately 0.1 mm to 1.0 mm, preferably approximately 0.3 mm to 1.0 mm.

[0167] The perforated inner tube 120 may have a perforated inner container wall 111. The perforated intermediate tube 121 may have a perforated outer container wall 113. The outer tube 122 is Career The outer wall 103 may be included and define the opening 105. The bottom cap 123 may have a bottom surface 101 and / or an annular bottom surface 115. The bottom cap 123 may also extend across the perforated inner tube 120 and have a channel end surface 116. The annular upper ring 124 and upper cap 125 may have an annular upper surface 114 and may have at least a portion of the upper surface 102. The annular seal ring 126 may have a seal 104.

[0168] The size of the perforations in the perforated inner tube 120 and the perforated intermediate tube 121 is selected to allow for a uniform flow of reactants and products through the catalyst while keeping the catalyst within the annular vessel 110. Therefore, it can be understood that their sizes depend on the size of the catalyst particles used. In an alternative configuration, the perforations may be larger, but with a filter mesh covering the perforations to ensure the catalyst remains within the annular vessel 110.

[0169] It can be understood that perforation may be any suitable configuration. In fact, when it is stated that a wall or tube is perforated, all that is required is that there are means to allow reactants and products to pass through the wall or tube.

[0170] The bottom surface 101, for example, the bottom cap 123, is another catalyst CareerIt may be molded to engage with the upper end of 10. For example, the bottom surface 101 may have an annular recess 130 around the perforated inner tube 120. The upper cap 125 may be another catalyst Career The upper cap can be shaped to engage with the annular recesses 130. For example, the upper cap 125 may have an annular ring 131 rising from the annular plug body 132. The annular ring 131 can be shaped and sized to fit into the annular recesses 130, as shown in Figure 13.

[0171] The bottom surface 101, for example, the bottom cap 123 and / or the channel end face 116, may include one or more drainage holes. If one or more drainage holes are present, they may be covered by a filter mesh.

[0172] The annular top ring 124 can be shaped and sized to engage with the upper end of the outer tube 122. The annular plug body 132 of the upper cap 125 can have an outer diameter configured to engage with the central opening of the annular upper ring 124. The engagement between the upper cap 125 and the annular upper ring 124 can function to hold the annular seal ring 126 in place.

[0173] The upper cap 125 may have a central inlet 134 within the annular plug body 132 to allow liquid and gas to enter the upper end of the inner channel 112. The annular ring 131 may have a lateral opening 133 that allows liquid and gas to reach the central inlet 134.

[0174] Career The exterior wall 103 may be smooth or it may be molded. Suitable shapes include pleats, corrugations, and the like.

[0175] Career The opening 105 in the outer wall 103 may have any configuration. In some embodiments, the opening 105 may be a hole or a slot.

[0176] The seal 104 can be formed in any suitable manner. However, it is generally sufficiently compressible to accommodate the minimum diameter of the reaction tube 8. The seal 104 is generally a flexible sliding seal. In some embodiments, the seal 104 is Career Exterior wall 103 or catalyst Career It may be equipped with a deformable flange 140 extending from the upper surface 102 of 10. The flange 140 is a catalyst Career When 10 is inserted into the reaction tube 8, it can be sized to be larger than the inner diameter of the reaction tube 8 so that it deforms to fit inside the reaction tube 8 and interact with the reaction tube 8.

[0177] In the example shown in Figure 9, the deformable flange 140 comprises the outer portion of the annular seal ring 126. The inner portion 141 of the annular seal ring 126 can define a clamping surface that is held between the upper cap 125 and the annular upper ring 124. The deformable flange 140 may be inclined with respect to the inner portion 141. The deformable flange 140 is a catalyst Career It may be sloped towards the top of 10.

[0178] Career The outer wall 103 may be continuous above the seal 104. Thus, the seal 104 may optionally be part of the upper surface 102, including the catalyst. Career It may be placed on top of 10, or Career If it is positioned above the opening 105 of the exterior wall 103, Career They may be placed at appropriate points on the exterior wall 103.

[0179] catalyst Career 10 may be configured to allow them to be mounted together in a stacked array. For example, adjacent catalysts. Career 10 may be engaged together by the engagement of one or more cooperative formations.

[0180] In several embodiments, each catalyst Career10 may include an upper cooperating formation 150 provided on or towards the upper end of the container 100 and a lower cooperating formation 151 provided on or towards the lower end of the container 100.

[0181] Adjacent catalysts Career 10 is one catalyst Career The catalyst adjacent to the lower cooperating formation 151 on 10 Career Can be engaged together by engagement with the upper cooperating formation 150 of 10.

[0182] The upper cooperating formation 150 and the lower cooperating formation 151 can be configured to be engaged and disengaged by the relative rotational movement of the adjacent catalysts 10. For example, the upper cooperating formation 150 and the lower cooperating formation 151 may take the form of a bayonet fitting. Career In some embodiments, the upper cooperating formation 150 is provided above the seal 104. For example, the upper cooperating formation 150 may be provided on the upper part of the annular ring 131 and / or on the upper part of the outer wall 103 or as part of it.

[0183] In some embodiments, the upper cooperating formation 150 is provided above the seal 104. For example, the upper cooperating formation 150 may be provided on the upper part of the annular ring 131 and / or Career May be provided on the upper part of the outer wall 103 or as part of it.

[0184] Catalyst Career Two or more of the catalysts 10 can be engaged together to form an insertion set as shown in FIGS. 12 and 13, for example. The insertion set may include, for example, two, three or more catalysts 10 stacked one on top of the other. Career 10 may be provided. Catalyst Career 10 may be permanently engaged with each other by means such as welding. However, more preferably, the catalysts 10 are releasably engaged with each other. The releasable engagement can be performed, for example, by the above-described cooperating formations 150, 151. Career 10 are releasably engaged with each other. The releasable engagement can be performed, for example, by the above-described cooperating formations 150, 151 of the catalyst.

[0185] The loading station 65 of the installation tool 20 may be configured to hold an insertion set of one, two, three or more catalysts 10, and the movable ram 22 is a catalyst Career 10 may be configured to hold an insertion set of one, two, three or more catalysts 10, and the movable ram 22 is a catalyst CareerA set of 10 may be configured to be pushed into the first selected reaction tube 8a of the tubular reactor 1 in a single stroke.

[0186] The installation tool 20 can be used to install the catalyst 10 in the first selected reaction tube 8a of the tubular reactor 1. The use of the installation tool 20 is described merely as an example when it is positioned in the headspace 3. Career In the first step, the installation frame 21 can be inserted through the access opening 11 of the tubular reactor 1 into the headspace 3 or the footer space 5 of the tubular reactor 1. The installation frame 21 may be lifted by the handle 29 manually or using a hoist.

[0187] The installation frame 21 can be connected to a power source 30 by a hose that can pass through the access opening 11.

[0188] Next, the installation frame 21 can be placed on the upper tube sheet 6. The installation frame 21 may be aligned with the selected reaction tube 8a to be filled such that the upper end of the selected reaction tube 8a is aligned with the opening 40 between the legs 26 of the installation frame 21.

[0189]

[0190] Next, if any of the legs 26 and their openings 28 are not aligned with the reaction tube 8b adjacent to the selected reaction tube 8a, the anchor 23 of each such leg 26 can be removed.

[0191] Next, one or more anchors 23 remaining attached to the installation frame 21 may be inserted into the reaction tube 8b such that the legs 26 and, if present, the support plates 27a, 27b contact the upper surfaces of the reaction tubes 8 and / or the upper tube sheet 6. The legs 26 and / or the support plates 27a, 27b may extend across the upper surfaces of the plurality of reaction tubes 8.

[0192] ​Next, the installation frame 21 may be stabilized using one or more stabilizing legs 70. The pin 72 may be actuated to engage with the upper tube sheet 6 between the reaction tubes 8. The stabilizing legs 70 may engage with the upper tube sheet 6 in particular at each position where the anchor 23 has been removed. However, the stabilizing legs 70 may still be engaged at positions where the anchor 23 is present.

[0193] Next, the stabilizing legs 70 may be adjusted to make the mounting frame 21 horizontal and / or so that the longitudinal (e.g., vertical) axis of the movable ram 22 is aligned with the longitudinal axis of the selected reaction tube 8a.

[0194] Next, open door 67, and the catalyst Career 10 or more catalysts Career An insertion set including 10 can be loaded into the loading station 65.

[0195] Next, with the door 67 closed again, the user interface 76 can be used to activate the installation tool 20, thereby activating the movable ram 22. The movable ram 22 then activates one or more catalysts. Career 10 can be pushed into the first selected reaction tube 8a.

[0196] During the movement of the movable ram 22, the alignment device 50 moves the catalyst Career 10 can be captured and vertically aligned. The conical surface 56 of the head 55 on the pin 51 is particularly important during the initial movement of the movable ram, as the rim 57 is at the top of the catalyst. Career Before contacting 10, the top catalyst Career It can engage with the central inlet 134 of the 10. Due to the inclined surface of the conical surface 56, the movement of the head 55 is directed towards the uppermost catalyst. Career 10 (and any other connected catalysts) Career 10) is biased toward correct vertical alignment. During the subsequent movement of the movable ram 22, the pin 51 may be retracted into the hole 52 against the biasing force of the spring 54, thereby moving the rim 57 toward the catalyst with the annular ring 131 housed within the gap space 58 of the alignment device 50. Career It can engage with the upper surface 102 of 10. During the subsequent movement of the movable ram 22, the catalyst Career 10 can be forcibly driven into the reaction tube 8a.

[0197] The process involves a catalyst being placed inside the selected reaction tube 8a. Career This may be repeated one or more times to insert one or more additional sets of 10.

[0198] The selected reaction tube 8a is able to react to the catalyst to the desired extent. Career Once filled in 10, the installation frame 21 can be removed by disengaging one or more anchors 23. The installation frame 21 can then be moved to align with another selected reaction tube 8a and reinstalled in the same manner as described above. Thus, each reaction tube 8 of the tubular reactor 1 can be sequentially filled using the installation tool 20.

[0199] The installation tool 20 is a catalyst Career The 10 may be configured to be installed simultaneously in two or more reaction tubes 8. For example, the movable ram 22 is a catalyst Career A first ram section for pushing 10 into the first selected reaction tube 8a, and a catalyst Career It may include a second ram section for simultaneously pushing 10 into a second selected reaction tube 8a. A third ram section may also be provided for simultaneously filling a third selected reaction tube 8a. Four or more ram sections may be provided as needed. The ram sections may be driven by a common actuator, such as a single hydraulic piston.

[0200] During insertion into reaction tube 8, the catalyst Career The seal 104 may be tightly engaged with the inner surface of the reaction tube 8. In particular, the engagement of the seal 104 with the reaction tube 8 may cause deformation of the seal 104.

[0201] The deformation of seal 104 indicates that the catalyst inside reaction tube 8 after installation is affected. CareerIt is possible to generate a resistance force that can help maintain the axial position of 10. Further, the deformation of the seal 104 can be used to facilitate a liquid-tight and / or gas-tight seal between the upper end of the catalyst Career 10 and the inner surface of the reaction tube 8.

[0202] When installed in the reaction tube 8, the catalysts Career 10 can form a vertically stacked arrangement with their longitudinal axes aligned and coincident.

[0203] In use in the tubular reactor 1 with downflow, the reactant(s) flow downward through the reaction tube 8, and thus first contact the upper surface 102 of the catalyst Career 10 at the top in the stack formation. The seal 104 blocks the passage of the reactant(s) around the side surface of the catalyst Career 10. Thus, the upper surface 102 guides the reactant inward to the central inlet 134 through the side opening 133 at the upper end of the inner channel 112 within the inner container wall 111 defined by the perforated inner tube 120.

[0204] Next, the reactant enters the annular container 110 through the perforated inner tube 120 and then passes radially through the catalyst bed towards the outer container wall 113 defined by the perforated intermediate tube 121. During this passage, the reactant contacts the catalyst and a reaction occurs to form a product.

[0205] Next, the unreacted reactant and the product flow out of the annular container 110 through the perforated intermediate tube 121. Then, the Career outer wall 103 defined by the outer tube 122 guides the reactant and the product Career upward between the inner surface of the outer wall 103 and the perforated intermediate tube 121 until reaching the opening 105 of the outer wall 103. Career Then they are guided through the opening 105 and Career flow downward between the outer surface of the outer wall 103 and the inner surface of the reaction tube 8 where heat transfer occurs.

[0206] Next, the unreacted reactant and the product are the catalysts at the bottom in the stack formation Career The upper surface 102 of 10 can come into contact with the upper surface 102, and the aforementioned process can be repeated. This pattern can be repeated as the reactants and products pass through the layer formation until they are collected from the lower end of the reaction tube 8.

[0207] Some of the product, particularly the liquid product, passes through the discharge holes provided at the channel end face 116 to the catalyst below the inner channel 112. Career It can be discharged into the inner channel 112 of 10. Then such a product is released into the catalyst. Career The 10 stacked formations can be continuously discharged and collected from the lower end of the reaction tube 8.

[0208] According to another aspect of this disclosure, a support unit 200 for installation inside the reaction tube 8 of a tubular reactor 1 is provided.

[0209] As shown in the figures, for example as shown in Figures 14 to 17, the support unit 200 has a first end 202 configured to engage with the support surface of the tubular reactor 1 when the support unit 200 is installed inside the reaction tube 8, and a catalyst that contacts the support unit 200.

For example, the upper rim 210 of the elongated body 201 provided at or toward the second end 203 is the catalyst Career The bottom surface 101 of the 10 can have a diameter of a size that engages with, for example, the bottom cap 123. In some embodiments, the upper rim 210 is a catalyst Career They may be sized to engage within the 10 annular recesses 130.

[0212] The support unit 200 may further include a spacer element 207 for aligning the support unit 200 with the inner surface of the reaction tube 8. The spacer element 207 may extend radially outward from the elongated body 201.

The cooperative formations 206 may be provided on or toward the second end 203. In some embodiments, the cooperative formations 206 are catalysts Career The 10 containers may be configured to engage with a lower cooperative formation 151 provided above or toward the lower end of the lower end of the container 100.

[0216] The cooperative formation 206 and the lower cooperative formation 151 may be configured to engage and disengage by relative rotational motion. For example, the cooperative formation 206 and the lower cooperative formation 151 may take the form of bayonet mounts.

[0217] During use, the support unit 200 and multiple catalysts are used. Career 10 is a support unit 200 that is aligned with the lower tube sheet 7 and multiple catalysts CareerThe 10 may be arranged in a stacked configuration that contacts the support unit 200 and installed inside the reaction tube 8 such that all catalysts inside the reaction tube 8 are located within the heat exchange zone 4. For example, all catalysts inside the reaction tube 8 may be positioned above the height of the lower tube sheet 7 in the heat exchange zone 4.

[0218] To facilitate this, the length of the elongated body 201 is such that the bottom catalyst is as shown in Figure 17. Career With 10 above the level of the lower tube sheet 7, the catalyst Career It can be appropriately configured to support 10 stacks.

[0219] Generally, after insertion, the support unit 200 is positioned at the bottom of the stacked arrangement. The support unit 200, particularly the first end 202, may engage with the support surface 12 of the tubular reactor 1.

[0220] During installation, for example, in a vertically oriented tubular reactor 1, the support unit 200 is first pushed onto the upper end of the reaction tube 8, followed by multiple catalysts. Career 10 may be pushed in. The support unit 200 may be installed alone or as part of an insertion set with the support unit 200 at the front. Alternatively, the catalyst Career The 10 and the support unit 200 may be installed at the lower end of the reaction tube 8 with the support unit 200 being the last to be installed.

[0221] The support unit 200 may be installed in the reaction tube 8 using the installation tool 20, as described above. In particular, the second end 203 may be configured to be pushed by the movable ram 22. For example, the elongated body 201 may have a flange 212 at or toward the second end 203, which is sized and shaped to engage with the rim 57 of the alignment device 50, as shown in Figure 16.

[0222] According to another aspect of this disclosure, a spacer unit 300 is provided for installation inside the reaction tube 8 of a tubular reactor 1.

[0224] The elongated body 301 may include a tubular member 304. The tubular member 304 may be hollow, and may define an internal bore 305 that extends completely through the elongated body 301 from a first end 302 to a second end 303.

[0225] The elongated body 301 may optionally have a contact surface 306 for engaging with the end face of the reaction tube 8 with respect to the reference plane of the reaction tube 8. The contact surface 306 may be provided on or toward the second end 303.

[0226] The second end 303 of the elongated body 301 may be provided with a socket 308 for engaging with the movable ram 22 of the installation tool 20. The inner flange 311 may be provided within the socket 308, which can be engaged by the movable ram 22, in particular by the rim 57 of the alignment device 50.

[0227] The diameter of the elongated body 301 is the catalyst Career It may be configured to engage with 10. For example, the lower edge 310 of the elongated body 301 provided at or toward the first end 302 is the catalyst Career The upper surface 102 of 10, for example, the upper cap 125 and / or the annular upper ring 124 and / or Career It may have a diameter sized to engage with the upper end of the outer wall 103. For example, the lower rim 310 may be provided on the annular skirt 312.

[0230] The catalyst at the outermost end (e.g., the top) of the stacked arrangement in the reaction tube 8 Career The position of 10 can be controlled by fixing the length of the spacer unit 300 between the lower rim 310 and the contact surface 306, and inserting the spacer unit 300 into the reaction tube 8 until the contact surface 306 engages with the reference surface of the reaction tube 8, for example, the upper end surface of the reaction tube 8.

[0231] The length of the elongated body 301 is such that all of the catalyst in the reaction tube 8 is located within the heat exchange zone 4. Career The system can be configured to allow the 10 stacks to be sufficiently moved into the reaction tube 8.

[0232] The spacer unit 300 may be installed so as to be positioned at the height of the upper tube sheet 6, and the catalyst Career Unit 10 is arranged in a stacked configuration below the spacer unit 300, and all of the catalyst in the reaction tube 8 is positioned below the height of the upper tube sheet 6 in the heat exchange zone 4.

[0233] catalyst Career After positioning 10 in the desired location, the spacer unit 300 can be left inside the reaction tube 8, or the spacer unit can be removed from the reaction tube 8 to reach the catalyst at the outermost end. Career The catalyst at the outermost end of the stacked array is positioned at a point where the catalyst inside is located within the heat exchange zone 4. Career You can keep 10.

[0234] Optionally, instead of spacer unit 300, a secondary spacer unit can be placed at the outermost catalyst. CareerIt may be installed relative to 10. The secondary spacer unit is the catalyst at the outermost end. Career The secondary spacer unit may extend between 10 and the support surface of the tubular reactor 1. For example, the support surface may be an upper support grid extending across the open end of the reaction tube 8. The secondary spacer unit supports the catalyst in the reaction tube 8 during the operation of the tubular reactor 1. Career This can mitigate or prevent upward creep of 10.

[0235] According to another aspect of this disclosure, a catalyst Career An ejector unit 400 is provided for use when discharging 10 from the reaction tube 8.

[0236] As shown in the illustration, for example, as shown in Figures 21 to 23, the ejector unit 400 is a catalyst Career The elongated body 401 includes a first end 402 configured to engage with the end of the 10 stacked bodies, and a second end 403 configured to engage with an installation tool, which may be the installation tool 20 described above.
