摘要：
A single-step cryogenic-distillation process that removes carbon dioxide (CO2), hydrogen sulfide (H2S), and other impurities from natural gas has been developed by ExxonMobil. Rather than avoiding the freezing of CO2 at cryogenic temperatures, solidification is allowed to take place in a very controlled fashion. The technology has potential to separate CO2 and other impurities from natural gas and to discharge these contaminants as a high-pressure liquid stream.
