Description
[technical field]
The present invention relates to technical field of chemical, a kind of specifically producing synthesis gas from coal that is applied to is produced methanation furnace and production method thereof in the natural gas field.
[background technology]
Natural gas is a kind of multi-component mixed gaseous fossil fuel, has become one of three big fossil energies of China; Its main component is an alkane; Wherein methane accounts for the overwhelming majority, and other has a spot of ethane, propane and butane, and it mainly is present in oil field and gas field; Also have a small amount of from the coal seam; Owing to do not produce no waste residue, waste water behind the combustion of natural gas, have safe in utilization, advantages such as calorific value is high, cleaning compared to coal, oil equal energy source, therefore do one's utmost to apply at key areas such as generating, chemical industry, domestic fuel, industrial fuels.
Though the natural storage level of the natural gas of China is sufficient relatively; But because the natural gas generation type causes its formation time very very long; If do not add the control exhaustive exploitation; Then the gas field of China is with exhaustion, and the scheme of therefore utilizing coal to obtain natural gas main component methane is indirectly very praised highly, and why this scheme receives and praising highly is because it has combined the basic characteristics of China's energy " rich coal oil starvation weak breath "; And in a disguised form solved the three wastes problem that the burning of the coal energy produces, therefore development is that the petroleum and natural gas alternative energy source of raw material is imperative with the coal.
The enforcement of this scheme is to utilize the synthesis gas of producing after the coal gasification, handles obtaining natural gas main component methane again through methanation:
At first; Coal gasification course is a thermochemical process; With coal or coal tar is raw material; Oxygen (or air or oxygen enrichment or pure oxygen), steam or hydrogen etc. are converted into fuel gas or synthesis gas through chemical reaction with the combustible constituent in coal or the coal tar as gasifying agent under hot conditions, its main component comprises CO, H
2, CO

4Deng, wherein CO, H
2In material gas, be called as effective gas, aspect gasifying process, mainly comprise shell evaporating method, texaco gasification method, multiinjector evaporating method, GSP evaporating method.
Secondly, the synthesis gas that obtains is handled through methanation, is mainly utilized chemical reaction to have:

The device of realizing above-mentioned reaction is a methanation furnace; All adopt at present the axial reaction type of furnace (referring to Fig. 1) of heat-insulating; Synthetic reaction gas gets in the methanation furnace from top; React generation methane through beds and discharge a large amount of heats simultaneously; Methane gas and unreacted synthesis gas etc. get into waste heat boiler (or claiming heat exchanger) from lower part outlet and carry out heat exchange, get into second methanation furnace after the heat absorption cooling with high-temperature gas and carry out methanation reaction once more, carry out three grades or fourth-order reaction successively.
But there is following shortcoming in the heat-insulating methanation furnace in actual production:
(1) the methanation furnace interior reaction temperature is wayward, and the heat of reaction that discharges in the course of reaction can not in time be withdrawn from, and therefore can cause the catalyst burn-off phenomenon, and the conversion ratio of one section methanation furnace is lower, and circulating flow rate is big, and energy consumption is high.
(2) the catalyst bed layer height is higher, and the synthetic reaction resistance drop is bigger, and the many more resistance drops of the platform number of series connection are big more, and energy consumption is just big more, and three series connection overall presure drops are up to 0.5～0.8MPa;
(3) because the architectural feature of adiabatic reaction causes the metal temperature of equipment compression shell higher, the compression shell thicker, to having relatively high expectations of material, equipment manufacturing cost is expensive;
In sum, though the technological process of preparing methane from coal seems simply, its technological process parameter and reaction unit all exist and remain improved defective in the actual production.
