Description

Description
A COOLING SYSTEM FOR ELIMINATION OF HEAT OF REACTION AT FISCHER-TROPSCH SLURRY BUBBLE
COLUMN REACTOR
Technical Field
[1] The present invention relates to a cooling system for elimination of heat of reaction from a Fischer-Tropsch (F-T) slurry bubble column reactor and, more particularly, to a cooling system for removing heat of reaction from an FT slurry bubble column reactor wherein the system receives synthetic gas (often referred to as "syngas") extracted from coal and controls temperature of heat of reaction generated during reaction of the syngas with a catalyst. Background Art
[2] It is well known that an indirect coal liquefaction system comprising a series of coal gasification, gas cleaning and liquefaction processes is employed to produce a wax type synthetic fuel from coal powder as a major raw material of the synthetic fuel so that the produced synthetic fuel is used as a raw material of fossil fuels.
[3] In this case, the gasification process is a process for conversion of coal into syngas primarily containing hydrogen and carbon monoxide.
[4] The gas cleaning process is a process for filtration and desulfurization of the syngas obtained from the gasification process and, in addition, for removing impurities and/or foreign materials.
[5] Lastly, the liquefaction process is a process for reaction of the clean syngas over a catalyst to convert the reaction product into a liquid phase synthetic fuel.
[6] In order to perform the liquefaction process, the syngas should be homogeneously dispersed into the FT slurry bubble column reactor to allow reaction of the syngas with an iron catalyst contained in a slurry of the reactor, thereby producing the synthetic fuel as a final product.
[7] The FT slurry bubble column reactor may perform a reaction of the syngas (CO + H
) with the iron (Fe) catalyst to produce the synthetic fuel, wherein the reaction is an exothermic reaction and causes an internal temperature of the reactor to be increased.
[8] Then, due to an increase in internal temperature, methane gas and carbon dioxide are increasingly generated in the FT slurry bubble column reactor to decrease selection of the synthetic fuel.
[9] Therefore, the above reactor basically requires maintaining the internal temperature of the FT slurry bubble column reactor at a desired level without variation.
[10] However, according to a conventional process as shown in FIG. 5, a cooling pipe 1 for circulation of water or steam is arranged inside an FT slurry bubble column reactor 200 in order to control an internal temperature thereof.
[11] However, such a construction of the reactor has problems in that a great amount of cooling water must be fed into the cooling pipe 1 and be continuously circulated within the reactor, thereby increasing energy consumption and, in addition, the construction exhibits very inferior cooling efficiencies. Disclosure of Invention Technical Problem
[12] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a cooling system for removal of heat of reaction (hereinafter referred to as "reaction heat") generated in an FT slurry bubble column reactor, wherein an injection line is arranged inside a cooling pipe to inject a small amount of cooling water into the cooling pipe under high pressure so as to control an exothermic temperature in the reactor by latent heat of evaporation, and the cooling water evaporated in the cooling pipe by heat in the reactor is discharged in a steam state so as to reduce energy consumption. Technical Solution
[13] In order to accomplish the above object of the present invention, there is provided a cooling system for removal of reaction heat from an FT slurry bubble column reactor, including: an FT slurry bubble column reactor; a plurality of first cooling pipes interconnected and arranged in a concentric structure on the top of the reactor; a plurality of second cooling pipes connected to the bottom of the first cooling pipes in a vertical downward direction; a cooling water injection line that has a diameter relatively smaller than an inner diameter of each of the first and second cooling pipes so as to be inserted into the same.

[20] FIG. 5 is a schematic diagram illustrating a conventional cooling pipe for removal of reaction heat from an FT slurry bubble column reactor. Best Mode for Carrying out the Invention
[21] Hereinafter, a detailed description will be given of exemplary embodiments of a cooling system for removal of reaction heat from an FT slurry bubble column reactor according to the present invention, with reference to the accompanying drawings.
[22] FIG. 1 is a schematic diagram illustrating a cooling system for removal of reaction heat from an FT slurry bubble column reactor according to the present invention; FIG. 2 is a first schematic top view illustrating the cooling system for removal of reaction heat from an FT slurry bubble column reactor of FIG. 1 ; and FIG. 3 is a second schematic top view illustrating the cooling system for removal of reaction heat from an FT slurry bubble column reactor of FIG. 1.
[23] As illustrated in FIGS. 1 to 3, the present invention provides a cooling system 100 for removal of reaction heat from an FT slurry bubble column reactor wherein the system receives syngas extracted from coal and controls temperature of the reaction heat generated during reaction of the syngas with a catalyst.
[24] Such a cooling system 100 generally comprises two parts, namely, a cooling pipe part and an injection line 20 inserted into the cooling pipe part.
[25] The cooling pipe part includes a plurality of first cooling pipes 10 and a plurality of second cooling pipes 11, wherein the first cooling pipes 10 are arranged on an inner top portion of the FT slurry bubble column reactor 200 in either a concentric structure (see FIG. 2) or a lattice structure (see FIG. 3) and are inter-connected together while the second cooling pipes 11 are connected to the bottom of the first cooling pipes 10 in a vertical downward direction.
[26] In this regard, inlets of the first cooling pipes 100 connected to the FT slurry bubble column reactor 200 are closed while outlets of the same are open.
[27] The injection line 20 constructed so as to be inserted in both the first cooling pipes 10 and the second cooling pipes 11 is provided to inject the cooling water into inner circumferential faces of the second cooling pipes 11, thus cooling the same.
[28] Accordingly, the injection line 20 duly has a smaller diameter than an inner diameter of each of the first and the second cooling pipes 10 and 11.
[29] In addition, the injection line 20 is coupled with a valve 22 for adjusting pressure of the cooling water in order to inject the same under a high pressure and an end part of the injection line 20 is closed to generate a pre-determined internal pressure therein. [30] The injection line 20 placed in the second cooling pipes 11 has a plurality of injection ports 21 to inject high pressure cooling water into the injection line by opening the valve 22. [31] Each injection port 21 has a diameter extending from an inner side to an outer side of the port so that the cooling water is injected and widely dispersed in the cooling pipe. [32] Hereinafter, a brief description will be given of a process for operating the cooling system for removal of reaction heat from an FT slurry bubble column reactor according to the present invention, with reference to related drawings. [33] FIG. 4 is a schematic diagram illustrating operation of cooling system for removal of reaction heat from an FT slurry bubble column reactor according to the present invention. [34] As illustrated in FIG. 4, syngas flows into the FT slurry bubble column reactor 200 and is combined with a slurry flowing in the reactor 200 to react with a catalyst, thus producing a synthetic fuel. [35] As to production of the synthetic fuel, the FT slurry bubble column reactor 200 performs a reaction of the syngas (CO + H ) with an iron (Fe) catalyst wherein the reaction is an exothermic reaction and causes an internal temperature of the reactor to be increased. [36] However, the internal temperature occurred by the reaction between the syngas and the iron catalyst must be maintained in the range of about 200 to 35O0C in the FT slurry bubble column reactor. Otherwise, methane gas and carbon dioxide are increasingly generated, thereby causing a decrease in selection of the synthetic fuel. [37] Therefore, it is necessary to reduce the internal temperature of the FT slurry bubble column reactor 200 to a desired level and constantly maintain the same temperature.
For this purpose, the present invention adopts a plurality of cooling pipes. [38] First of all, a cooling process is conducted by passing the cooling water through the injection line 20 before flowing into the FT slurry bubble column reactor 200, so as to increase the internal pressure to a desired level at which the cooling water can be injected via the valve 22. [39] Such an internal pressure may be more easily attained according to a shape of the injection line 20 closed at the end thereof. [40] Subsequently, the cooling water flows throughout a cross-section of the FT slurry bubble column reactor 200 via the injection line 20 placed in the first cooling pipes 10 and the cooling water flow is transported into each injection line 20 placed in the second cooling pipes 11. [41] Such transported cooling water passes through injection ports 21 of the injection line
20 and is injected to an inner circumferential face of each second cooling pipe 11. [42] Following that, the cooling water injected to the second cooling pipe 11 may reduce the temperature of the second cooling pipe 11 by latent heat of evaporation which in turn decreases the temperature of the FT slurry bubble column reactor 200.
[43] The evaporated cooling water is converted into steam by the high temperature and the steam is discharged out of the outlet of the first cooling pipe 10.
[44] The above cooling process is advantageous in that a small amount of cooling water is injected into the cooling pipe under a high pressure so as to control an exothermic temperature in the reactor by latent heat of evaporation, and the cooling water evaporated in the cooling pipe by heat in the reactor is discharged in a steam state which may be used as an alternative energy source and may reduce energy consumption. Industrial Applicability
[45] As is apparent from the above, the cooling system for removal of reaction heat from an FT slurry bubble column reactor according to the present invention has beneficial features in that an injection line is arranged inside a cooling pipe to inject a small amount of cooling water into the cooling pipe under high pressure so as to control an exothermic temperature in the reactor by latent heat of evaporation and, in addition, the cooling water evaporated in the cooling pipe by heat in the reactor is discharged in a steam state which may be used as an alternative energy source and may reduce energy consumption.
[46] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various changes and/or modifications are possible, without departing from the scope and spirit of the invention. Therefore, these modifications and/or changes may be included in the scope of the invention, as defined in the accompanying claims.
