Description

Technical Field

[0001] This invention relates to the field of hydrocarbon preparation technology, and in particular to a method and apparatus for hydrocarbon preparation. Background Technology

[0002] In recent years, with the increasing global demand for renewable energy, solar and wind power have been widely promoted due to their clean and environmentally friendly characteristics. However, the inherent characteristics of renewable energy, such as intermittency, periodicity, and volatility, have brought significant challenges to the green production of olefins and aromatics.

[0003] Because aviation kerosene has an energy density 80 times that of existing commercial lithium-ion batteries, it will be difficult for the aviation industry to decarbonize through electrification in the foreseeable future, making sustainable aviation fuel an inevitable choice. Furthermore, the rapid development of the aviation industry and carbon emission targets necessitate that the synthesis of sustainable aviation fuel reach at least tens of millions of tons in the future.

[0004] Currently, the technology for producing aviation fuel through biomass hydrogenation is relatively mature, but the raw material requirements for producing jet fuel through biomass hydrogenation cannot meet the needs of large-scale production. This makes it difficult to achieve the green and sustainable production of olefins and aromatics. Summary of the Invention

[0020] Optionally, the tertiary energy utilization system is used to prepare olefins and aromatics, wherein the tertiary energy utilization system for preparing olefins and the tertiary energy utilization system for preparing aromatics are connected in parallel, and a splitter is provided between the secondary energy utilization system and the tertiary energy utilization system.

[0021] Optionally, the primary energy utilization system includes a fluid transport pipeline through which a fluid working medium flows; the energy storage device consists of one or more fixed beds connected in series or parallel.

[0022] The energy supply equipment is used to collect energy and convert the energy into heat energy to heat the first energy storage particles filled in the fluidized bed charging device.

[0023] The fluidized bed energy charging device is used to perform heat exchange treatment between the first particle and the fluid working medium, and to transport the heat-exchanged fluid working medium to the fixed bed energy storage device through the fluid transport pipeline;

[0024] The fixed-bed energy storage device is used to receive the heated fluid working medium output by the fluidized bed energy charging device during the heat storage stage, and to exchange heat between the fluid working medium and the second energy storage particles in the fixed bed to store thermal energy in the second energy storage particles of the fixed bed.

Simultaneously, steam is generated during the cooling of the first syngas produced in the secondary system, also for steam power generation. In the tertiary energy utilization system, steam is generated during the cooling process of the crude hydrocarbon products after the reaction, via a second heat exchanger, for steam power generation. Thus, the primary, secondary, and tertiary energy utilization systems improve energy utilization efficiency and achieve green and sustainable development of hydrocarbons. Attached Figure Description

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Reference Figure 1 The diagram shows a schematic of a hydrocarbon preparation apparatus according to an embodiment of the present invention. The apparatus includes a primary energy utilization system 101, a secondary energy utilization system 102, and a tertiary energy utilization system 103.

[0039] The primary energy utilization system 101 includes energy supply equipment, fluidized bed energy charging equipment, fixed bed energy storage equipment, and steam power generation equipment.

[0040] The energy supply equipment can provide an energy source for the primary energy utilization system 101. For example, the energy source can be renewable energy sources such as solar energy and wind energy. Taking solar energy as an example, the energy supply equipment can include a heliostat and a receiver. The heliostat can automatically adjust its angle according to the changes in the sun's position, so that the sunlight it reflects is focused on the receiver. The receiver transfers the sun's heat to the charging equipment through an intermediate energy storage medium, which includes, but is not limited to, gas, molten salt, magma, and solid particles.

[0041] In this embodiment of the invention, the primary energy utilization system 101 may include a pneumatic conveying device, which is configured to provide a fluid working medium to the air distribution plate, the fluid working medium being able to fluidize solid particles at high speed.

[0042] In this embodiment of the invention, the fluidized bed energy charging device includes a fluidized bed and first energy storage particles filled within the fluidized bed. An energy supply device heats the first energy storage particles of the fluidized bed energy charging device to achieve energy transfer. Then, the energy is output from the fluidized bed after heat exchange between the fluid working medium and the first energy storage particles. The selection of the first energy storage particles can be determined according to the actual application scenario; in this embodiment of the invention, no excessive restrictions are imposed on this selection.

[0043] In this embodiment of the invention, the energy charging device is equipped with a high-porosity air distribution plate, and a cavity is provided below the air distribution plate. Solid particles can be selectively filled into the cavity, uniformly distributing the intermediate energy storage medium. The air distribution plate can support the solid particles. The solid particles within the energy charging device have a wide particle size distribution, and their state remains stable at temperatures ranging from 25°C to 3000°C. The energy charging device allows the internal particles to operate in a dense-phase fluidized bed or circulating fluidized bed state.

[0044] Fluidized bed energy charging equipment may include a heating device, which may utilize, but is not limited to, electric heating devices such as resistance and electromagnetic induction, or energy sources including but not limited to wind energy, solar energy, and green electricity, geothermal energy, and industrial waste heat generated by the system itself and other sources to heat the internal particles.

[0045] When the energy in the receiver is dominant in the energy storage device, the heating device of the fluidized bed charging device, as an auxiliary device, can be turned on or off. When the energy in the receiver is relatively small in the energy storage device, the receiver, as an auxiliary device, can be turned off or off.

[0046] In this embodiment of the invention, the fixed-bed energy storage device can be configured to be filled with a second energy storage particle. The fixed-bed energy storage device can be composed of a single or multiple fixed beds connected in series or parallel. When the fixed beds are connected in series, the energy storage and release pipeline system cannot be opened simultaneously. When the energy storage devices are connected in parallel, the energy storage and release pipeline system can be opened simultaneously.

[0047] In fixed-bed thermal storage in a fixed-bed energy storage device, the working fluid enters from the top and exits from the bottom of the fixed-bed energy storage device through energy storage pipes, which are vertically inserted into the fixed bed.

[0048] In this embodiment of the invention, the fixed-bed energy storage device is connected to a steam power generation device, which may include a chilled water pump, a heat exchanger, a steam pressure reducing station, and a steam turbine generator set. The chilled water pump provides cooling water, the heat exchanger facilitates heat exchange between the cooling water and the working fluid, the steam pressure reducing station reduces the pressure of the generated steam, and the steam turbine generator set generates electricity using the steam. The steam generated by the fixed-bed energy storage device can serve as a reaction feedstock and energy source for the secondary energy utilization system 102.

[0049] The secondary energy utilization system 102 in this embodiment of the invention includes a gasifier containing the material to be gasified and a first heat exchanger. The gasifier can be used for chemical reactions. Specifically, the gasifier may include a material silo and a heating chamber, which are integrated and connected by a gate valve to control the material's falling speed. The raw materials in the material silo include, but are not limited to, coal, biomass, municipal solid waste, and solid waste. The gasifier includes, but is not limited to, any one of a coal gasifier, a supercritical water gasifier, and a plasma gasifier.

[0050] The first heat exchanger in the secondary energy utilization system 102 is connected to the outlet of the reactor and is used to cool the first syngas at the outlet.

[0051] The three-stage energy utilization system 103 in this embodiment of the invention may include a reactor for preparing hydrocarbons, a distillation column, and a second heat exchanger.

[0052] The reactor is used to chemically react various raw materials to prepare crude hydrocarbon products, the distillation column is used to purify and store the required hydrocarbons from the crude hydrocarbon products, and the second heat exchanger is used to cool the crude hydrocarbon products fed into the distillation column.

[0053] The functions of each part in the hydrocarbon preparation device are described below:

[0054] The primary energy utilization system 101 is used to store thermal energy in a fixed bed energy storage device through energy supply equipment and fluidized bed energy charging equipment during the thermal storage stage. During the heat release stage, the energy storage device and steam power generation equipment are used to heat cooling water to generate first steam, and the first steam is used to generate steam power to provide electrical energy for the device.

[0055] The secondary energy utilization system 102 is used to react the first steam as raw material with the gasified material in the gasifier to generate the first syngas, and to cool the first syngas with the cooling water of the first heat exchanger to obtain the second syngas and the second steam. The second steam is input into the steam power generation equipment for steam power generation.

[0056] The three-stage energy utilization system 103 is used to generate crude hydrocarbon products in a reactor based on the second syngas, and to cool the crude hydrocarbon products through the cooling water of the second heat exchanger to obtain the cooled crude hydrocarbon products and the third steam. The cooled crude hydrocarbon products are then fed into a distillation column for purification, and the third steam is fed into a steam power generation device for power generation.

[0057] In one embodiment of the present invention, the primary energy utilization system 101 includes a fluid transport pipeline through which a fluid working medium is circulated; the fixed bed energy storage device is composed of one or more fixed beds connected in series or parallel.

[0058] The energy supply equipment is used to collect energy and convert it into heat energy to heat the first energy storage particles filled in the fluidized bed charging device.

[0059] For example, solar energy can be collected by a heliostat and then converted into thermal energy through photothermal technology, which can then be used to heat the first energy storage particles.

[0060] Fluidized bed energy storage equipment is used to perform heat exchange between the first particle and the fluid working medium, and then transport the heat-exchanged fluid working medium to the fixed bed energy storage equipment through a fluid transport pipeline.

[0061] In the heat storage stage, the fixed bed energy storage device receives the heated fluid working medium output from the fluidized bed energy charging device and exchanges heat with the second energy storage particles in the fixed bed to store the thermal energy in the second energy storage particles of the fixed bed. In the heat release stage, the heat stored in the second energy storage particles is used to heat the fluid working medium introduced into the fixed bed and the heated fluid working medium is output to the steam power generation equipment.

[0062] Steam power generation devices use the heat carried by a fluid working medium to heat incoming water to generate steam, and then generate steam power based on the steam.

[0063] In one embodiment of the present invention, the apparatus further includes a water electrolysis system, which includes a water electrolysis device, a hydrogen storage tank, an oxygen storage tank, and a compressor. The water electrolysis device is used to electrolyze water using electrical energy generated by the first energy utilization system to generate hydrogen and oxygen. The hydrogen storage tank is used to store hydrogen. The oxygen storage tank is used to store oxygen. The compressor is used to compress the hydrogen output from the hydrogen storage tank and then transport it through a pipeline to the reactor of the third energy utilization system for chemical reaction to generate crude hydrocarbon products.

[0064] In this embodiment of the invention, by combining water electrolysis technology, high-value hydrogen and oxygen can be generated. The hydrogen can be used as a reaction raw material in a three-stage energy utilization system and reacted with the second syngas in a reactor to generate crude hydrocarbon products.

[0065] In one embodiment of the present invention, the apparatus further includes a third heat exchanger connected to the top of the distillation column. The third heat exchanger is used to collect the energy of the low-temperature gas leaving the top of the distillation column and to pre-cool the crude hydrocarbon product using this energy. By setting up the third heat exchanger, the cold energy of the low-temperature gas at the top of the olefin distillation column can be recovered and then used for pre-cooling the crude hydrocarbon product, achieving high-efficiency energy utilization.

[0066] In this embodiment of the invention, a temperature gauge can be installed in the hydrocarbon preparation device to monitor the temperature at various points in the device and control the hydrocarbon preparation device to stably produce hydrocarbons.

[0067] In one example, the secondary energy utilization system also includes a first temperature gauge located at the outlet of the first heat exchanger. The first temperature gauge is used to monitor the temperature change of the second syngas. In practical applications, it is necessary to ensure that the temperature of the second syngas is not lower than a first set temperature. The first set temperature can be set according to the actual scenario, and this first set temperature must ensure that the second syngas can continue to react in the tertiary energy utilization system.

[0068] In another example, the three-stage energy utilization system also includes a second temperature instrument located at the outlet of the second heat exchanger. The second temperature instrument is used to monitor the temperature of the hydrocarbon-based crude product at the outlet of the second heat exchanger to ensure that the temperature of the hydrocarbon-based crude product is not lower than a second preset temperature. The second preset temperature can be set according to the actual scenario. The second preset temperature must ensure that the hydrocarbon-based crude product can continue to achieve efficient purification in the distillation column.

[0069] In another example, the apparatus also includes a third temperature gauge located at the inlet of the distillation column. The third temperature gauge is used to monitor the temperature of the hydrocarbon-based crude product at the inlet of the distillation column, ensuring that the temperature of the hydrocarbon-based crude product is not lower than a third preset temperature. The third preset temperature can be set according to the actual scenario, and this third preset temperature must ensure that the hydrocarbon-based crude product can continue to achieve efficient purification in the distillation column.

[0070] In another example, the first energy utilization system includes a fourth thermometer located at the steam outlet. The fourth thermometer monitors the temperature of the steam generated by the first energy utilization system. It continuously monitors the temperature of the high-temperature steam leaving the steam power generation equipment, ensuring that the temperature does not fall below a fourth set temperature. This fourth set temperature can be set according to the actual scenario, and it must ensure that the steam can continue to react in the gasifier to generate the first syngas. In this embodiment of the invention, ultra-high temperature steam power generation is used, and the steam temperature can be higher than 1100°C.

[0071] In one embodiment of the present invention, a three-stage energy utilization system is used to prepare olefins and aromatics. The three-stage energy utilization system for preparing olefins and the three-stage energy utilization system for preparing aromatics are connected in parallel, and a splitter is provided between the two-stage energy utilization system and the three-stage energy utilization system.

[0072] By setting up a splitter, the second synthesizer generated in the secondary energy utilization system can be divided into two streams to achieve olefin production and aromatics production respectively.

[0073] In this embodiment of the invention, the secondary energy utilization system can generate high-temperature syngas by reacting high-temperature steam with coal / biomass in a gasifier. The reaction temperature of the gasifier can be around 1000°C. The energy of the high-temperature syngas leaving the gasifier can be transferred to steam to generate electricity. The cooled medium-temperature syngas can also be used to produce aromatics and olefins.

[0074] In this embodiment of the invention, the first energy utilization system can achieve energy storage and release through a combination of fluidized bed and fixed bed, thereby generating steam based on thermal energy to provide raw materials for the second-stage energy utilization system. Since the reaction in the gasifier is endothermic, the high-temperature steam generated by the first-stage energy utilization system can also serve as an energy source to power the reaction. Furthermore, the steam can be used for steam power generation, which can power the entire hydrocarbon preparation apparatus. Simultaneously, steam can also be generated during the cooling of the first syngas produced in the second-stage energy utilization system, thus enabling steam power generation. In the tertiary energy utilization system, during the cooling process of the crude hydrocarbon product after the reaction, steam can also be generated through the second heat exchanger, thus enabling steam power generation. Therefore, the first-stage, second-stage, and tertiary energy utilization systems can improve energy utilization efficiency and achieve green and sustainable development of hydrocarbons.

[0075] like Figure 2 The diagram shown is a schematic diagram of an apparatus for preparing olefins and aromatics according to an embodiment of the present invention; the apparatus includes a primary energy utilization system, a secondary energy utilization system, a tertiary energy utilization system, and a quaternary energy utilization system.

[0076] The primary energy utilization system includes a heliostat, a receiver, a charging device (i.e., a fluidized bed charging device), an energy storage device (a fixed bed energy storage device), a pneumatic conveying device, a steam power generation device, a temperature instrument 1 (i.e., the fourth temperature instrument), and a fluid working medium installed in the energy storage pipeline. The steam power generation device includes a heat exchanger 1, a temperature-controlled steam depressurization station, and a steam turbine generator set.

[0077] The secondary energy utilization system includes a gasifier, heat exchanger 4 (i.e., the first heat exchanger), and temperature instrument 4 (i.e., the first temperature instrument).

[0078] The three-stage energy utilization system includes a splitter, a syngas-to-olefins system, and a syngas-to-aromatics system. The syngas-to-olefins system includes an olefin reactor, heat exchanger 2 (i.e., the second heat exchanger), thermometer 2 (i.e., the second thermometer), an olefin distillation column, and an olefin storage tank. The syngas-to-aromatics system includes an aromatics reactor, heat exchanger 3 (i.e., the second heat exchanger), thermometer 3 (i.e., the second thermometer), an aromatics distillation column, and an aromatics storage tank.

[0079] The fourth-level energy utilization system includes the heat exchanger 5 and the temperature instrument 5.

[0080] The water electrolysis hydrogen production system includes a water electrolysis unit, a hydrogen storage tank, an oxygen storage tank, and a compressor.

[0081] Based on the above structure, the process for the synergistic and sustainable preparation of olefins and aromatics among the various parts is as follows:

[0082] (1) The primary energy utilization system is based on the generation of high-temperature steam from renewable energy sources and the generation of electricity from the steam:

[0083] The heliostat can automatically adjust its angle according to the changes in the sun's position, so that the reflected sunlight is focused on the receiver. The receiver transfers the sun's heat to the charging device through a fluid working medium. The charging device then transports the heat-carrying material to the separator for filtration of the first energy storage particles. The fluid working medium is then transported to the energy storage device. Through heat exchange between the fluid working medium and the second energy storage particles filled in the energy storage device, the thermal energy is stored in the energy storage device.

[0084] A low-temperature working fluid is introduced into the energy storage device. After heating, the heated working fluid is output to heater 1. Once the cold water pump starts, the cooling water flowing into the heater exchanges heat with the working fluid, generating high-temperature steam. Part of this high-temperature steam is then transported to the secondary energy utilization system, and the remainder is sent to a steam depressurization station for depressurization treatment before being transported to a steam turbine generator set for steam power generation. The steam power generation process in the primary energy utilization system operates at temperatures exceeding 1100℃.

[0085] (2) Secondary energy utilization system generates syngas:

[0086] High-temperature steam is used as both raw material and energy source and transported to a gasifier to undergo a chemical reaction with other raw materials. This reaction is endothermic and occurs at approximately 1000°C. The reaction produces high-temperature syngas (i.e., the first syngas), which is then transported to heat exchanger 4 for cooling to obtain medium-temperature syngas (i.e., the second syngas). The medium-temperature syngas is then transported to a tertiary energy utilization system.

[0087] During the cooling process, cooling water can be converted into steam, which can then be used to generate steam power.

[0088] (3) Hydrogen production system for water electrolysis:

[0089] Hydrogen is produced by electrolyzing water using electricity from the primary energy utilization system. The hydrogen is then transported to a compressor for compression and then used as a raw material to be transported to the tertiary energy utilization system.

[0090] (4) The three-stage energy utilization system uses a splitter to separate the intermediate-temperature syngas and hydrogen, respectively, and feeds the two raw materials into the olefin reactor and the aromatics reactor for chemical reaction to obtain crude olefins and crude aromatics. Among them, the synthesis of aromatics and olefins from syngas is a strongly exothermic reaction with a temperature of 400℃~500℃. After cooling the crude olefins with cooling water introduced through heat exchanger 2, it is sent to the olefins distillation column for distillation to obtain olefins, which are then stored in olefin tanks. After cooling the crude aromatics with cooling water introduced through heat exchanger 3, it is sent to the aromatics distillation column for distillation to obtain aromatics, which are then stored in aromatics tanks.

[0091] During the cooling process, the cooling water is heated to generate steam, which can then be used to generate steam power.

[0092] (5) The four-energy utilization system can use heat exchanger 5 to recover the low-temperature gas energy leaving the top of the olefin distillation column, and can use this energy to pre-cool the olefin tail gas to be distilled (i.e. the cooled crude olefin product).

[0093] Reference Figure 3 The diagram illustrates a flowchart of a hydrocarbon-based method according to an embodiment of the present invention, applied to a hydrocarbon-based generation apparatus.

The secondary energy utilization system includes a gasifier containing the material to be gasified and a first heat exchanger. The tertiary energy utilization system includes a reactor for preparing hydrocarbons, a distillation column, and a second heat exchanger.

[0094] The primary energy utilization system is used to store thermal energy in a fixed-bed energy storage device through energy supply equipment and fluidized bed energy charging equipment during the thermal storage stage. During the heat release stage, the energy storage device and steam power generation equipment are used to heat cooling water to generate first steam, and the first steam is used to generate steam power to provide electricity for the device.

[0095] The secondary energy utilization system is used to react the first steam as raw material with the gasified material in the gasifier to generate the first syngas, and to cool the first syngas with cooling water from the first heat exchanger to obtain the second syngas and the second steam. The second steam is input into the steam power generation equipment for steam power generation.

[0096] The three-stage energy utilization system is used to generate crude hydrocarbon products in a reactor based on the second syngas, and to cool the crude hydrocarbon products through the cooling water of the second heat exchanger to obtain the cooled crude hydrocarbon products and the third steam. The cooled crude hydrocarbon products are then fed into a distillation column for purification, and the third steam is fed into a steam power generation unit to generate electricity.

[0097] The method for generating hydrocarbon groups based on this hydrocarbon group generation device may specifically include the following steps:

[0098] Step 301: The first-level energy utilization system is used to generate first-level steam and generate steam power to provide electrical energy for the device;

[0099] Step 302: The first steam is reacted with the gasified material in the gasifier using a two-stage energy utilization system to generate the first syngas, and the first syngas is cooled by the cooling water of the first heat exchanger to obtain the second syngas and the second steam. The second steam is input into the steam power generation equipment for steam power generation.

[0100] Step 303: In the three-stage energy utilization system, crude hydrocarbon products are generated in the reactor based on the second syngas, and the crude hydrocarbon products are cooled by the cooling water of the second heat exchanger to obtain the cooled crude hydrocarbon products and the third steam. The cooled crude hydrocarbon products are then fed into a distillation column for purification, and the third steam is fed into a steam power generation device for power generation.
