专利汇可以提供Desulfurization with subsequent h{11 s absorption专利检索，专利查询，专利分析的服务。并且Process for removal of a selected constituent from a vapor stream which comprises contacting the vapor stream in a high pressure absorption zone with a first stream of lean absorbent, mixing the resulting rich absorbent with a second stream of lean absorbent in a low pressure contacting zone, and separating the resulting mixture in a separation zone under conditions sufficient to provide selected constituent and separated lean absorbent. In a preferred embodiment, the separation zone comprises a phase separator and a low pressure absorption zone, the resulting mixture is passed from the low pressure contacting zone into the phase separator, and a resulting vapor stream is passed from the phase separator into the low pressure absorber wherein it is contacted with a third lean absorbent stream. The process has particular utility in the removal of selected constituent, such as an acid gas or mixture of acid gases, in a high pressure absorption zone maintained at a pressure in excess of 1,000 psig. Particular application is in the removal of hydrogen sulfide from a hydrogenation reaction zone, such as a hydrotreating zone or a hydrocracking zone, wherein a hydrocarbon charge stock containing organic sulfur compounds is desulfurized.，下面是Desulfurization with subsequent h{11 s absorption专利的具体信息内容。
