Definitions
- the invention relates to a process for the production of synthetic natural gas.
- the invention relates to a process for producing and providing synthetic natural gas at pressures suitable for direct feed into natural gas pipelines.
- SNG synthetic natural gas
- the composition of the primary gas from the coal gasification further conditioning stages, such as adsorption to remove sulfur-containing components of zinc oxide-containing adsorbents, and additional conversion stages such as shift reactors to adjust the hydrogen and CO content of the synthesis gas.
- the purified and conditioned synthesis gas is then heated to the inlet temperature in the first methanation of about 260 ° C by heat exchange against recycled product gas of the first methanization stage.
- the reactor pressure is about 25 bar (a).
- the product gas recirculation serves to control the Congestion due to the high exothermicity of the above reactions.
- the first reaction stage of the methanation is followed by another methanation stage, which is operated without product gas recirculation.
- the enriched in its methane content and thus energy content product gas of methanation is cooled and dried and thus has a quality that is suitable for introduction or addition to conventional natural gas pipelines.
- the gas pressure of the SNG must be increased by compression in a pipeline head station to the pipeline operating pressure, according to Ullmann 's Encyclopedia of Industrial Chemistry, Sixth Edition, 1998 Electronic Release, keyword "Natural Gas", Chapter 4.1.1 "Pipeline Transmission” can be up to 80 bar (a).
- FIG. 2 there shows a method in which the synthesis gas first passes through one or more methanization reactors, producing a primary methanization product gas which is subsequently cooled to separate water by condensation from the primary methanization product gas. Part of the thus dried methanization primary product is subsequently recycled as recycle gas before the entrance of the methanization reactors.
- the remaining part of the primary methanization product gas is fed as feed to a further adiabatic methanization reactor ("trim reactor”) .
- trim reactor adiabatic methanization reactor
- the process is preferably carried out such that at least two series-connected methanization primary reactors are present, the first reactor containing fresh synthesis gas feed gas
- the recycle stream is supplied to the second reactor and both the product gas of the first reactor and fresh synthesis gas feed gas are fed to the second reactor
- a cooled and dried methanization product gas is obtained in this process, the pressure of which is increased before it is discharged into a pipeline network got to.
- the SNG produced by methanation is often to be fed into an existing pipeline system for transport to consumers. Due to the pressure loss that the synthesis gas suffers when passing through the methanation plant and the lower pressure level in the methanation plant compared to the pipeline pressure it is necessary to compress the methane-rich product gas after the methanation plant to pipeline pressure.
- the present invention has for its object to provide for the production of SNG from synthesis gas on an industrial scale and the subsequent feeding of the generated SNG in a pipeline system, a method that is characterized by particular energy efficiency.
- the solution of the object according to the invention results essentially from the characterizing features of claim 1 in conjunction with the features of the preamble. Further advantageous embodiments of the invention will become apparent from the dependent claims.
- the adaptation of the target pressure of the product gas of methanation ie usually the pipeline pressure, after the last reaction stage, and after cooling and drying of the product gas.
- the methane-rich product gas after the methanization plant must be compressed by a lower pressure on the pipeline pressure due to the Ent stress on the plant parts. Due to the higher pressure ratio, defined as the ratio of outlet pressure to inlet pressure of the compressor, more energy must be expended for the product compressor and for the cycle compressor together than in the inventive method.
- the subject matter of the process according to the invention is that the compression of the synthesis gas to adjust the target pressure takes place before the main reaction zone and / or before or in the post-reaction zone, instead of - as in the processes in the prior art - only after the ethanization plant.
- the temperature increase due to the compression is used for the heating of the synthesis gas, which explains the energetic advantages of the process.
- the sum of the compression energy for auxiliary, cycle and product compressors is lower with this circuit.
- the additional compressor is arranged before or in the post-reaction zone, the utilization of the more favorable pressure ratio leads to the energetic advantages of the process according to the invention.
- An arrangement in the post-reaction zone can take place if it comprises a plurality of reactors. In this case, the arrangement of the additional compressor before the last reactor of the post-reaction zone has proven to be particularly favorable.
- the SNG product gas Before being introduced into the pipeline system, the SNG product gas may need to be cooled and dried, as is also provided in the prior art. Preferred embodiments of the invention
- the setting of the target pressure is carried out by compression in front of the main reaction zone and before the synthesis gas fresh gas stream is combined with the recycle stream.
- an additional compressor is arranged before the merger point of the synthesis gas fresh gas stream with the recycle stream. This can be followed, for example, the usually existing Feinentschwefelungseck. Since the synthesis gas fresh gas stream leaving the fine desulfurization stage is comparatively cold, part of the supplied compression energy can advantageously be used to preheat the synthesis gas fresh gas stream. In addition, the cycle compressor is relieved. In this embodiment of the invention particularly large energy savings are achieved, as the following numerical examples show.
- a final compression of the product gas of the methanation plant in a product compressor can be completely dispensed with. If it is advantageous to use a product compressor, this can be dimensioned considerably smaller in terms of its compressor performance than in a methanization system according to the prior art.
- the setting of the target pressure by compression takes place before or in the post-reaction zone, namely after the removal of the recycle stream after the main reaction zone.
- the additional compressor can be connected upstream of the cooler before entering the post-reaction zone; In this case, a part of the supplied compression energy is advantageously used for steam generation. It is particularly preferred, however, downstream of the cooler, since then a cooler and dryer gas can be compressed.
- the additional compressor can also be switched directly in front of the first catalyst bed of the post-reaction zone, whereby, as in the above case, part of the supplied compression energy can be used to preheat the gas stream entering the post-reaction zone.
- An arrangement of the additional compressor in the post-reaction zone is possible if it comprises several reactors.
- a preferred embodiment of the invention provides that the heating of the main reaction zone supplied synthesis gas feed stream is carried out in indirect heat exchange against a hot process own or foreign process fluid flow. Particular preference is given to heating the synthesis gas feed stream supplied to the main reaction zone in indirect heat exchange with the recycle stream.
- the heat integration obtained in this way contributes to the energy efficiency of the method according to the invention.
- the addition of the recycle stream to the syngas fresh gas stream also serves to control the exotherm in the main reaction zone.
- the dilution of the syngas fresh gas stream and the consequent reduction in the concentration of carbon oxides in the syngas feed stream reduces the risk of carbon deposits forming in the main reaction zone catalyst beds as well as at the catalyst bed exit.
- Preferred embodiments of the invention provide that the reaction of the synthesis gas feed stream to a methane-rich intermediate gas stream occurs in the main reaction zone at temperatures between 200 and 700 ° C and at pressures between 15 and 120 bar (a) such that further reaction of the intermediate Gas stream to a methane-rich product gas stream in the post-reaction zone at temperatures between 150 and 500 ° C and at pressures between 30 and 120 bar (a), and reacting the synthesis gas feed stream in the main reaction zone and / or the intermediate gas stream in the post-reaction zone by means of methanation catalysts based on nickel, iron or precious metals.
- the use in particular of nickel catalysts for the methanation of carbon oxides with hydrogen is known per se and is used industrially, so that a large number of suitable catalysts is commercially available.
- the molar ratio of hydrogen to carbon monoxide in the synthesis gas fresh gas stream is between 0.4 and 5.0 mol / mol. Considering the stoichiometry of the reactions discussed above For the formation of methane by hydrogenation of carbon oxides, these molar ratios have been found to be particularly suitable.
- An advantageous embodiment of the method according to the invention provides that the main reaction zone comprises at least two catalyst beds, and that a portion of the synthesis gas fresh gas stream is passed before entering the second catalyst bed of the main reaction zone.
- This measure which is known per se, contributes significantly to distributing the high exothermicity of the methanation reaction more uniformly over both catalyst beds, so that a thermal overload of the first catalyst bed, which leads to accelerated deactivation of the catalyst used there, is avoided.
- the target pressure in the process according to the invention is preferably between 30 and 120 bar (a), more preferably between 30 and 90 bar (a). This corresponds to the usual working pressure in natural gas pipelines.
- the process according to the invention can be used for the processing of synthesis gas produced by gasification of coal.
- the coal gasification is followed by the following steps known to the person skilled in the art for conditioning the synthesis gas: partial conversion of the CO to hydrogen for setting the required H 2 / CO ratio (CO shift), and removal of acidic gas constituents, eg , Example by washing with cold methanol by the Rectisol® process in which sulfur compounds are almost completely and carbon dioxide partially removed.
- the inventive method can also for the processing of synthesis gas from other sources, eg. B. from natural gas or by gasification of biomass or liquid, hydrocarbon-containing starting materials synthesis gas can be used.
