Abstract

The present disclosure relates to the field of fluid handling systems and discloses a manifold system (300) for fluid delivery. The system (300) includes a first set of solenoid valves (SOVs) [(V1-V2), (V1-V3)], a second set of SOVs [(V4-V5), (V4-V6)], a plurality of isolation valves [(I1-I2, I4-I5), (I1-I6)], at least one first shuttle valve [(S1), (S4-S6)], and at least one redundant shuttle valve [(S3), (S4'-S6')]. Each set of SOVs [(V1-V2), (V1-V3), (V4-V5), (V4-V6)] includes at least two SOVs [(V1-V2), (V1-V3), (V4-V5), (V4-V6)] arranged in parallel. The SOVs [(V1-V2), (V1-V3), (V4-V5), (V4-V6)] together form series-parallel redundancy. Each isolation valve [(I1-I2, I4-I5), (I1-I6)] is coupled to an SOV [(V1-V2, V4-V5), (V1-V6)] and facilitates hot swapping of that SOV [(V1-V2, V4-V5), (V1-V6)]. The redundant shuttle valves [(S3), (S4'-S6')] provide redundancy for the first shuttle valve [(S1), (S4-S6)] and facilitate the flow of fluid from each of the first set of SOVs [(V1-V2), (V1-V3)] to each of the second set of SOVs [(V4-V5), (V4-V6)], thereby improving system safety and availability.

Description

Technical Field

[0001] The present disclosure relates generally to manifold systems for continuous process delivery and more particularly to safe and usable manifold systems for the downstream petroleum complex and petrochemical industries.

[0002] definition

[0003] As used in this disclosure, the following terms are generally intended to have the meanings set forth below, unless the context in which they are used indicates otherwise.

[0004] Manifold—The term “manifold” hereafter refers to a device designed to converge multiple junctions into a single channel or to branch a single channel into multiple junctions to facilitate the transport of fluids.

[0005] Hot Swap—The term "hot swap" hereafter refers to the process of adding and replacing components of a system without having to power down the system.

[0006] Shuttle Valve—The term "shuttle valve" hereafter refers to a three-way valve with a center float. This valve has two input ports and one output port. With input from one input port, the ball moves and blocks the other input port, allowing fluid connection between one input port and the output port. With input from both input ports, the ball moves to the center, allowing flow from both input ports to exit through the output port. Background Art

[0007] The following background information in this document is related to the present disclosure but is not necessarily prior art.

[0008] Currently, all petrochemical, chemical, refining, and oil industries are focused on improving the safety and availability of the systems involved in performing various industrial processes. A key factor in defining the safety of an industrial process is the ease with which a system can be fully or partially shut down in the face of a significant hazard. In contrast, availability is defined as the degree to which a system remains operable under different operating conditions, avoiding false trips. In the processing and manufacturing industries, valves play a vital role in controlling various operations. The arrangement of these valves determines the safety and availability of the industrial systems in which they are used. For example, to enhance safety, valves are often arranged in series. Therefore, if a single valve fails, the entire row automatically fails. To enhance availability, valves are arranged in parallel. In this case, if a single valve fails, the system continues to operate because the parallel valves are functional.

[0009] Fluid transport systems in process plants typically include numerous valves. Valves are categorized as either manual or automatic. One type of automatic valve is the 3 / 2 poppet valve, also known as a 3 / 2 solenoid valve. A 3 / 2 poppet valve designates a 3-port, 2-position poppet valve. A 3 / 2 valve differs from a conventional 2 / 2 valve in the presence of an additional port for diverting the flow. In one position, fluid flows from the poppet valve's inlet to the application port, while in the other position, fluid flows from the inlet to the outlet port, which is connected to the discharge port. Failure of such poppet valves is inevitable in process plants. When a valve fails, it must be isolated from the system for maintenance and replacement, impacting system reliability and availability.

[0010] Therefore, one of the key problems associated with conventional systems is the repair and recovery process, which inevitably requires shutting down the entire process to repair and recover the valve. In continuous process industries, this means a huge production loss over the entire time it takes for the valve to recover.

[0011] In order to overcome the above problems, a manifold system for improving the safety and availability of an industrial process is described in patent publication WO 2015 / 155786 A1. Figure 1 A circuit diagram of a typical manifold system (hereinafter referred to as "system (100)") described in patent publication WO2015 / 155786 is shown. The system (100) includes four solenoid-operated valves (SOVs) (V1, V2, V4, V5) and four isolation valves (I1, I2, I4, I5) connected between a fluid inlet (102) and a fluid outlet (104). The system (100) includes only two shuttle valves (S1, S2). One shuttle valve (S1) connects the two SOVs (V1, V2) located near the fluid inlet (102) to the SOV (V4) located near the fluid outlet (104), and the other shuttle valve (S2) connects the two SOVs (V4, V5) located near the fluid outlet (104) to the fluid outlet (104). No shuttle valve connects the two SOVs (V1, V2) located near the fluid inlet (102) to another SOV (V5) located near the fluid outlet (104). This reduces the availability of the system. For example, when only two SOVs (V1, V5) function and the other SOVs (V2, V4) fail, the system (100) will not allow fluid to flow from the fluid inlet (102) to the fluid outlet (104) because the shuttle valve (S1) does not allow fluid to flow from the SOV (V1) to the SOV (V5). Therefore, even when both SOVs (V1 and V5) function, the output of the system (100) is zero.

[0012] The following truth table (Table 1) describes the output of the system (100) for different operating states of the SOVs (V1, V2, V4, V5). The operating states include an open (ON) state / powered state (depicted by a logic 0) and a closed (OFF) state / de-powered state (depicted by a logic 1). A valve in the closed state or de-powered state indicates a faulty valve that requires repair and replacement.

[0013]

[0014] Table 1

[0015] The following observations can be made from the truth table above:

[0016] (i) When both SOVs (V1, V2) located near the inlet (102) are in an open state and at least any one of the SOVs (V4, V5) located near the outlet (104) is in an open state, fluid can pass through the system (100) to the outlet (104).

[0017] (ii) When both SOVs (V4, V5) located near the outlet (104) are in an open state and at least any one of the SOVs (V1, V2) located near the inlet (102) is in an open state, fluid can pass through the system (100) to reach the outlet (104).

[0018] (iii) When at least any one of the SOVs (V1, V2) located near the inlet (102) is in an open state and the SOV (V4) connected to the shuttle valve (S1) is in an open state, fluid can pass through the system (100) to the outlet (104).

[0019] (iv) When the two SOVs (V2, V5) connected in series are in the open state, fluid can pass through the system (100) to the outlet (104).

[0020] However, when the SOV (V1) located near the inlet (102) is in an open state and the SOV (V5) located near the outlet (104) is in an open state, no fluid is transferred from the inlet (102) to the outlet (104) because the shuttle valve (S1) is not connected to the SOV (V5). This results in reduced system availability.

[0021] Conventional systems, such as Figure 1 The system shown does not provide shuttle valve redundancy. Furthermore, when there are multiple failed valves and all failed valves need to be replaced, there is no means to bypass the entire fluid delivery system or provide redundancy for the entire fluid delivery system.

[0022] Therefore, there is a need for a manifold system that facilitates fluid flow from all SOVs located near the fluid inlet to all SOVs located near the fluid outlet, thereby improving system availability.

[0076] Now refer to Figures 2 to 5 A manifold system for fluid delivery of the present disclosure (hereinafter referred to as "system (300)") is described. The system (300) is designed to improve the safety and reliability of the industrial processes in which it is used.

[0077] refer to Figure 3 、 Figure 4 and Figure 5 The manifold system (300) of the present disclosure includes a plurality of manifold assemblies (10). Each manifold assembly (10) includes a first set of SOVs [(V1-V2), (V1-V3)], a second set of SOVs [(V4-V5), (V4-V6)], a plurality of first isolation valves [(I1-I2, I4-I5), (I1-I6)], at least one first shuttle valve [(S1), (S4-S6)], and at least one redundant shuttle valve [(S3), (S4'-S6')]. The first set of SOVs [(V1-V2), (V1-V3)] is positioned near the fluid inlet (102) and includes at least two SOVs [(V1-V2), (V1-V3)] arranged in parallel. The second set of SOVs [(V4-V5), (V4-V6)] is connected in series with the first set of SOVs [(V1-V2), (V1-V3)]. A second set of SOVs [(V4-V5), (V4-V6)] is positioned near the fluid outlet (104) and includes at least two SOVs [(V4-V5), (V4-V6)] arranged in parallel. Each first isolation valve [(I1-I2, I4-I5), (I1-I6)] is coupled to each SOV [(V1-V2, V4-V5), (V1-V6)]. Each first isolation valve [(I1-I2, I4-I5), (I1-I6)] is adapted to facilitate hot swapping of an associated SOV [(V1-V2, V4-V5), (V1-V6)].

[0078] The circuit of the manifold system (300) is configured so that the redundancy provided by the SOVs [(V1-V2, V4-V5), (V1-V6)] is subject to hot swapping by means of the first isolation valves [(I1-I2, I4-I5), (I1-I6)]. For example, referring to Figure 3 , when the SOV (V1) is in the de-energized state and the remaining SOVs (V2, V4, V5) are in the energized state, the fluid at the SOV (V1) inlet does not escape. In this state, the corresponding first isolation valve (11) is activated to perform hot replacement. This isolates the fluid supply to the SOV (V1), which can now be removed for maintenance. This ensures that the process does not stop and the system (300) continues to work with the other working valves (V2, V4, V5).

[0079] like Figure 3-Figure 5As shown, a first shuttle valve [(S1), (S4-S6)] is connected between a first set of SOVs [(V1-V2), (V1-V3)] and a second set of SOVs [(V4-V5), (V4-V6)]. Redundant shuttle valves [(S3), (S4'-S6')] are configured to provide redundancy to the first shuttle valves [(S1), (S4-S6)] in a manner that facilitates the flow of fluid from each of the first set of SOVs [(V1-V2), (V1-V3)] to each of the second set of SOVs [(V4-V5), (V4-V6)], thereby improving system availability. The fluid to be transferred from the fluid inlet (102) to the fluid outlet (104) includes at least one of air, neutral gas, liquid, and natural gas.

[0080] In one embodiment, the system (100) further includes at least one second shuttle valve (S2), S7-S9) connecting the second set of SOVs (V4-V5), V4-V6) to the fluid outlet (104). The second shuttle valve (S2), S7-S9) can be further connected to an actuator (106) that is actuated upon receipt of fluid. According to one embodiment, the actuator (106) is a rack and pinion arrangement having springs attached at opposite ends.

[0081] Therefore, in Figure 3 In a system (100), a first set of SOVs, i.e., SOVs (V1, V2) located near a fluid inlet (102), are connected to shuttle valves (S1, S3). The first shuttle valve (S1) is connected to the SOV (V4) and the redundant shuttle valve (S3) is connected to the SOV (V5) through first isolation valves (I4) and (I5), respectively. The second set of SOVs (V4, V5) is connected to the fluid outlet (104) through a second shuttle valve (S2).

[0082] The following truth table (Table 2) describes Figure 3 and Figure 4 The output of the system (300) under different operating states of SOV (V1, V2, V4, V5). The states include an open state / power-on state (depicted by a logic 0) and a closed state / power-off state (depicted by a logic 1).

[0083]

[0084] Table 2

[0085] As can be seen from Table 2 (row 14), the introduction of an additional redundant shuttle valve (S3) in the system (300) allows fluid to be available at the outlet (104) even when the SOVs (V2 and V4) are in a de-energized / closed state, thereby improving the reliability and availability of the system.

[0086] Advantageously, a plurality of manifold assemblies (10) such as Figure 4 The manifolds (10) are connected in parallel as shown. This results in a further improvement in system reliability and availability. Each manifold assembly (10) is connected to the fluid inlet (102) via a second isolation valve (M1, M2). Each manifold assembly (10) is connected to the fluid outlet (104) via a common outlet shuttle valve (S10). This arrangement makes it easier to replace one or more faulty SOVs (V1, V2, V4, V5) or faulty shuttle valves (S1, S2, S3) online (i.e., when the system (300) is running). Even Figure 3 The four SOVs (V1, V2, V4, V5) of the embodiment can be removed and replaced simultaneously without affecting the flow of fluid through the outlet (104). The possibility of failure or complete shutdown of the system (300) is also minimized.

[0087] In one embodiment, the first isolation valve [( I1 - I2 , I4 - I5 ) ( I1 - I6 )] and the second isolation valve ( M1 , M2 ) are manually operated valves (MOVs).

[0088] like Figure 1 and Figure 2 As shown, in one embodiment, the system (300) includes a plurality of indicators [(A,B,C,D), (A,B,C,D,E,F)], wherein each indicator [(A,B,C,D), (A,B,C,D,E,F)] is connected to each SOV [(V1-V2, V4-V5), (V1-V6)] to indicate the status of the SOV [(V1-V2, V4-V5), (V1-V6)]. In another embodiment, the system (300) includes a plurality of pressure sensors [(P1, P2, P3, P4), (P1, P2, P3, P4, P5, P6)], wherein each pressure sensor [(P1, P2, P3, P4), (P1, P2, P3, P4, P5, P6)] is connected to each SOV [(V1-V2, V4-V5), (V1-V6)] to indicate the state of the SOV [(V1-V2, V4-V5), (V1-V6)]. In yet another embodiment, the system (300) includes an indicator [(A, B, C, D) (A, B, C, D, E, F)] and a pressure sensor [(P1, P2, P3, P4), (P1, P2, P3, P4, P5, P6)].

[0089] refer to Figure 2In an embodiment, the system (300) includes a bypass valve (B1) for providing an alternative bypass path for fluid from the fluid inlet (102) to the fluid outlet (104). This facilitates easy replacement of single or multiple SOVs [(V1-V2, V4-V5), (V1-V6)] and shuttle valves (S1-S9, S1'-S6'). The bypass valve (B1) can be connected to the fluid outlet (104) via another shuttle valve (S11). The system (300) may also include an indicator (G) and / or a pressure sensor (PB1) associated with the bypass valve (B1) to indicate its status.

[0090] Figure 5 An embodiment of a manifold system (300) having six SOVs (V1-V6) is depicted. In this embodiment, the manifold assembly (10) includes a plurality of third shuttle valves (S1'-S3'). Each third shuttle valve (S1'-S3') is operably coupled at its input port to a first shuttle valve (S4-S6) and a redundant shuttle valve (S4'-S6') to facilitate the flow of fluid from each of the first set of SOVs (V1-V3) to each of the second set of SOVs (V4-V6) to improve shuttle valve redundancy and system availability. Thus, the system (300) includes six SOVs (V1-V6) and six first isolation valves (11-16) connected to a fluid outlet (104) via twelve shuttle valves (S4-S9, S1'-S6'). The outlet of the SOV (V1) is connected to the input port of the shuttle valves (S4, S4', S5, S6'). The outlet of SOV (V2) is connected to the input port of shuttle valve (S4, S5, S5', S6). The outlet of SOV (V3) is connected to the input port of shuttle valve (S4', S5', S6, S6'). The output port of shuttle valve (S4, S4') is connected to the input port of shuttle valve (S1'). The output port of shuttle valve (S5, S5') is connected to the input port of shuttle valve (S2'). The output port of shuttle valve (S6, S6') is connected to the input port of shuttle valve (S3'). The output port of shuttle valve (S1') is connected to the inlet of SOV (V4) through the first isolation valve (I4). The output port of shuttle valve (S2') is connected to the inlet of SOV (V5) through the first isolation valve (I5). The output port of shuttle valve (S3') is connected to the inlet of SOV (V6) through the first isolation valve (I6). The outlet of SOV (V4) is connected to the input port of shuttle valve (S7). The outlet of SOV (V5) is connected to the input port of shuttle valve (S7, S8). The outlet of SOV (V6) is connected to the input port of shuttle valve (S8). The output ports of shuttle valves (S7, S8) are connected to the input port of shuttle valve (S9), and shuttle valve (S9) is connected to the fluid outlet (104).

[0091] The following truth table (Table 3) shows the output of the system (500) for various operating states of the SOVs (V1-V6).

[0092]

[0093] Table 3

[0094] As can be seen from the truth table above, fluid is received at the fluid outlet (104) even when only SOVs (V1 and V6) or SOVs (V3 and V4) are in the energized state and the remaining SOVs (V2-V5) or (V1, V2, V5, V6) are in the de-energized state.

[0095] like Figure 5 The system (300) shown provides shuttle valve redundancy and facilitates individual isolation of the SOVs (V1-V6) and shuttle valves (S1-S8). Furthermore, the inclusion of additional shuttle valves (S1'-S6') increases system availability and also minimizes the likelihood of system failure / complete shutdown.

[0096] In one embodiment, the SOV [(V1-V2, V4-V5), (V1-V6)] is a 3 / 2 poppet valve, and the isolation valve [(I1-I2, I4-I5), (I1-I6)] is a 3 / 2 valve.

[0097] In one embodiment, the system (300) includes at least one exhaust device (108) to discharge exhaust residues to the atmosphere.

[0098] Advantageously, the SOV [(V1-V2, V4-V5), (V1-V6)] and the first isolation valve [(I1-I2, I4-I5), (I1-I6)] are merged together to eliminate the need for two different mounting arrangements.
