一种煤气化装置来原料气的分离方法和装置

本发明涉及一种煤气化装置来的基本组分为一氧化碳，氢气和甲烷的原料气，将一氧化碳/氢气分离成一股流体供下游作为合成气，分离液化甲烷(LNG)为另一股流体进行商业销售的分离系统。该分离系统采用洗涤塔、CH 4 -CO精馏塔双塔流程，通过合理控制回流比，大部分原料合成气经洗涤后在塔顶形成甲烷含量低于1％的合成气；洗涤后的液相送入CH 4 -CO精馏塔，分离出来的CH 4 液化为LNG。由于CH 4 -CO精馏塔流量小，与单塔流程相比减少分离功耗10％，而且塔板数也可以减少；双塔流程降低了塔高、节约了成本，同时又使从原料合成气到返回的合成气阻力损耗最小。本发明废气排放量少、环保、节能，具有很好的经济效益和社会效益。

Production of methanol

A continuous process for producing methanol including the steps of producing synthesis gas i.e. H2 + CO by the partial oxidation of a hydrocarbonaceous feed in a free-flow non-catalytic synthesis gas generator, adjusting the mole ratio (H2/CO) of the process gas stream to a value in the range of about greater than 2 to 12 by noncatalytic thermal direct water-gas shift, cooling the process gas stream by indirect heat exchange with water to produce steam for use in the process, purifying the gas stream preferably with a portion of the methanol product, catalytically reacting the purified synthesis gas stream under methanol producing conditions, and separating methanol from liquid impurities. All steps are preferably carried out at a pressure which is substantially that in the synthesis gas generator less ordinary line drop. Optionally, a portion of the liquid impurities e.g. dimethylether, water, and mixed alcohols, are introduced into the synthesis gas generator to reduce the specific consumption of free-oxygen gas and to increase the yield of synthesis gas.

The present invention relates to a power generation system applied to realize high efficiency power generation with full carbon capture when using solid or liquid hydrocarbons or carbonaceous fuels. More specifically, the solid or liquid fuel is first partially oxidized in a partial oxidation reactor. The resulting partially oxidized stream comprising fuel gas is quenched, filtered, cooled and then directed to the combustor of the power production system as combustion fuel. The partially oxidized stream is combined with the compressed recycle CO 2 stream and oxygen. The combustion stream expands across the turbine to generate power and passes through a recuperator heat exchanger. The expanded and cooled exhaust stream is washed to provide the recycle CO 2 stream, which is compressed and passes through the recuperator heat exchanger and the POX heat exchanger in a manner useful for providing increased efficiency to the composite systems. .

Installation and the method of production of the synthesis- gas from the natural gas

FIELD: chemical industry; installations and the methods of production of the synthesis-gas from the natural gas. SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to the installation and the method for simultaneous production from the natural gas of the methanol synthesis-gas, the ammoniac synthesis-gas, carbon monoxide and carbon dioxide. The installation consists of the in-series connected to each other assembly units and includes: the first reactor (A), in which at feeding of oxygen realize the transformation of the natural gas into the synthesis gas consisting of carbon monoxide, carbon dioxide, hydrogen and the steam; the second reactor (B), in which exercise the regular transformation of carbon monoxide into carbon dioxide; if necessary the compressor (C) using which the formed gases may be contracted; absorbing apparatus D, which serves for absorption of carbon dioxide and production of he mixture of monoxide with hydrogen used for synthesizing methanol; the refrigerating separator E, in which at feeding of the liquid nitrogen receive the ammoniac synthesis gas and simultaneously produces carbon monoxide, argon and methane. The invention allows to increase profitability of the installation due to production at one installation of several products. EFFECT: the invention ensures the increased profitability of the installation due to production at one installation of several products. 15 cl, 1 dwg, 1 tbl ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß RU (19) (11) 2 286 942 (13) C2 (51) ÌÏÊ C01B C01C C07C C07C 3/02 (2006.01) 1/04 (2006.01) 29/151 (2006.01) 31/04 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2004136579/15, 22.03.2003 (30) Êîíâåíöèîííûé ïðèîðèòåò: 13.06.2002 DE 10226209.8 (73) Ïàòåíòîîáëàäàòåëü(è): ËÓÐÃÈ Àà (DE) (43) Äàòà ïóáëèêàöèè çà âêè: 10.08.2005 R U (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 22.03.2003 (72) Àâòîð(û): ÄÀÂÅÉ ...
