METHOD FOR TREATMENT OF A GASEOUS MIXTURE COMPRISING HYDROGEN AND HYDROGEN SULPHIDE

摘要

The invention relates to a method for treatment of a gaseous mixture comprising hydrogen, H2S and possibly other components such as hydrocarbons. The aim of the invention is to separate the hydrogen from the other components of the mixture whilst retaining the initial pressure of the gaseous mixture. According to the invention a treatment unit is used, comprising a pressure-modulated adsorption unit (PSA) with an integral compressor which compresses the recycle gas within the PSA.
