Abstract: Acid gas compounds are removed from a process gas such as, for example, syngas or natural gas, by flowing a feed gas into a desulfurization unit to remove a substantial fraction of sulfur compounds from the feed gas and flowing the resulting desulfurized gas into a CO2 removal unit to remove a substantial fraction of CO2 from the desulfurized gas.

Abstract: A water gas shift reaction is carried out on a feed gas comprising carbon monoxide to produce carbon dioxide and hydrogen gas. The feed gas is split into multiple input streams flowed into respective reactors coupled in series. Steam is supplied to the input stream fed to the first reactor. The shift reaction is carried out in each reactor, with an overall reduced consumption of steam relative to the amount of gas shifted. The water gas shift reaction may be performed in conjunction with removing acid gas compounds from a process gas such as, for example, syngas or natural gas, by flowing a feed gas into a desulfurization unit to remove a substantial fraction of sulfur compounds from the feed gas and flowing the resulting desulfurized gas into a CO2 removal unit to remove a substantial fraction of CO2 from the desulfurized gas.

Abstract translation: 对包含一氧化碳的进料气体进行水煤气变换反应以产生二氧化碳和氢气。 进料气体分成多个输入流，流入分别串联的反应器。 将蒸汽供应到输入到第一反应器的输入流。 在每个反应器中进行转移反应，相对于气体量的转移，蒸汽的消耗总体减少。 水煤气变换反应可以结合从工艺气体例如合成气或天然气中除去酸性气体化合物，通过将进料气体流入脱硫单元以从进料中除去大量硫化合物 气体并将得到的脱硫气体流入CO 2去除单元以从脱硫气体中除去大部分的CO 2。
