Abstract

Sweet and sour: Many natural gas reserves are contaminated with sour, acid-forming gases such as H2S and CO2. Two processes for the removal of CO2 from CH4 are compared in terms of volume and energy consumption. It is found that the traditional amine-absorption process and a process based upon condensed rotational separation are complimentary, and the combination of both technologies could allow the exploitation of previously uneconomical gas fields.
