摘要
A process for the separation of the components of a gas mixture to be treated comprising methane, nitrogen and at least one hydrocarbon having at least two carbon atoms, or a mixture of these hydrocarbons, including introducing the gas mixture to be treated into a first distillation column thereby producing, at the column top, a first gas stream enriched in methane and, at a level lower than that of the top of the column, another gas stream; and introducing the other gas stream resulting from step a) into a second distillation column, at a level lower than that of that of the top of the second column, thereby producing, at the top of this column, a second gas stream rich in methane.
