摘要： A method of separating acid gases, particularly carbon dioxide, from methane by cryogenic distillation. The method includes the step of adding helium to the stream to be separated to increase the critical pressure of the methane-carbon dioxide present. The cryogenic distillation tower may then be operated at a higher pressure and without the formation of solid carbon dioxide.
