Definitions
- the present invention belongs to the field of integrated processes for the production of light olefins, ammonia and urea in order to improve their energy efficiency and reduce the amount of emissions produced. More specifically the invention relates to the integration of a fluid catalytic cracking process, preferably for the generation of light olefins, to a steam reforming hydrogen generation process and an air separation unit (ASU) to produce intermediates, such as hydrogen (H 2 ), nitrogen (N 2 ) and carbon dioxide (C 2 ), which will serve as nitrogen fertilizer production units such as ammonia (NH 3 ) and urea.
- ASU air separation unit
- Anhydrous ammonia is a gas obtained by the direct reaction of nitrogen from air with hydrogen from various sources, such as natural gas and naphtha, for example.
- Natural gas appears as the main raw material for the generation of hydrogen needed in ammonia production. About 90% of the world's ammonia production comes from natural gas, which appears as an essential factor for future projects. for the production of nitrogen fertilizers.
- This amount is usually obtained by burning natural gas to provide heat for the production of the synthesis gas (mixture of hydrogen, carbon dioxide and nitrogen obtained from steam reforming and / or self-reforming).
- hydrocarbon such as natural gas or naphtha
- one of the alternatives currently employed is the generation of hydrogen by gasification of charges such as coal, coke. oil, and other wastes.
- the hydrocarbon is gasified in the presence of pure oxygen obtained after separation of the nitrogen removed from the air in an air separation unit (ASU).
- ASU air separation unit
- US patent application 2007/0245787 discloses a production process of ammonia and nitrogen fertilizers based on partial oxidation of fossil fuel, co-producing polycarbonate and with low CO 2 emission.
- the fossil fuel reacts with oxygen from the air and vapor in an electrically discharged plasma, producing the polycarbonate, hydrogen and nitrogen that are later separated, purified and used for ammonia synthesis.
- US patent application 2004/028595 describes a method for the production of ammonia from a nitrogen-hydrogen mixture obtained from the self-thermal reforming of natural gas.
- Natural gas is fed to a self-heating reformer together with an oxygen-rich stream at temperatures ranging from 900 ° C to 1200 ° C, a pressure of 40bar to 100bar and in the presence of a reforming catalyst.
- the crude synthesis gas leaving the reformer is cooled, and fed to a displacement reactor to convert CO to H 2 and thus obtain a conversion to synthesis gas with a high H 2 content in the dry state.
- the synthesis gas is then subjected to a purification process to remove CO 2 , CO and CH 4 and thus produce a mixture of N 2 -H 2 which is routed to ammonia synthesis.
- US 6,586,480 discloses an integrated process for the production of liquid hydrocarbons and ammonia.
- a current Synthesis gas obtained by reforming natural gas with steam and oxygen-containing mixture, undergoes a Fischer-Tropsch process producing liquid hydrocarbons, carbon dioxide, nitrogen and hydrogen. After separation, the nitrogen and hydrogen streams are routed to the ammonia production process.
- it is not necessary to use a displacement unit to convert CO to H 2 as in conventional processes since CO reacts with part of H 2 in the Fischer-Tropsch reactor to produce liquid hydrocarbons.
- the present invention relates to a process comprising a fluid catalytic cracking unit, preferably for the production of light olefins, more specifically ethylene and propene, to a steam reforming hydrogen generating unit and a so that the currents produced are used in the synthesis processes of ammonia and urea.
- the scope of the invention relates to an integrated process that includes a fluid catalytic cracking unit, preferably adjusted to operate under conditions such that there is maximization of the production of light olefins such as, but not restricted to, ethylene and propylene.
- a fluid catalytic cracking unit preferably adjusted to operate under conditions such that there is maximization of the production of light olefins such as, but not restricted to, ethylene and propylene.
- that such unit uses for coke regeneration deposited on the surface of the cracking catalyst, an oxygen-rich stream mixed with an inert, preferably the inert being CO 2 , and the oxygen used was generated in an air separation unit which in turn generates a by-product stream.
- the integrated process includes a steam reforming unit in which such unit uses as a load a hydrocarbon stream from the fluid catalytic cracking unit, such stream preferably consisting of hydrogen and hydrocarbons in the range.
- C1 to C2 flue gas
- C3 to C4 liquefied petroleum gas
- hydrocarbons having 5 or more carbon atoms and boiling range below 220 ° C (naphtha)
- the mixture from the reforming unit consisting primarily of CO 2 , CO and H 2> may be conducted to a shift reactor to convert CO to H 2 by reacting CO with water vapor in the presence of a catalyst, wherein the resulting mixture of CO 2 and H 2 may be routed to a CO 2 and H 2 separation unit, such as a PSA unit, to obtain a pure H 2 current.
- the integrated process includes utilizing the pure H 2 stream generated in the reforming unit and displacement reactor and, together with the pure N 2 stream generated in the air separation unit, being routed to a unit.
- ammonia production whereby the ammonia produced can be passed along with the CO 2 rich current produced in the fluid catalytic cracking unit regenerator to a urea production reactor.
- the invention allows to reduce the carbon dioxide emissions due to the use of C0 2 produced during the regeneration stage of the FCC catalyst to be utilized in the synthesis of urea.
- the charge for the steam reforming unit consists of hydrocarbons of higher molecular weight (fuel gas, LPG and / or naphtha), the reforming being carried out with water vapor only.
- fuel gas LPG and / or naphtha
- the invention further allows that by using a single source of air as a source of oxygen and nitrogen for both cracking catalyst regeneration and nitrogen fertilizer production greater energy efficiency is achieved.
- the present invention allows simultaneously: the reduction of C0 2 emissions to the atmosphere, the use of heavy loads and low value in the production of light olefins, in addition to the maximum use of all the current involved thereby increasing the efficiency achieved.

- the regenerated catalyst (10) returns to the FCC reactor at a high temperature sufficient to provide heat for the process endothermic reactions.
- Such streams are separated by recovering a first stream comprising ethylene and propene (11) and a second stream which may comprise gas. fuel, LPG and / or naphtha (12).
- the stream comprising fuel gas, LPG, naphtha and / or (12) is forwarded to a unit of hydrogen generation (13) generating two streams, one of C0 2 (14), which is optionally directed to the production unit urea and a hydrogen stream (15) which is routed to an ammonia production unit (16).
- the ammonia production unit (16) is further charged with a nitrogen stream (17) from the air separation unit (6).
- the stream comprising ethylene and propylene (11) is subsequently harnessed in the production of basic petrochemicals.
- Ammonia (19) and urea (20) streams can be recovered as end product or as a filler for other fertilizer production processes.
