A process of separating acid gases consisting of carbon dioxide and/or hydrogen sulfide from hydrocarbons is disclosed. Methane is first separated from the hydrocarbon stream to produce a substantially methane free hydrocarbon stream containing acid gases, ethane and heavier hydrocarbon components.

A process of separating acid gases consisting of carbon dioxide and/or hydrogen sulfide from hydrocarbons is disclosed. Methane is first separated from the hydrocarbon stream to produce a substantially methane free hydrocarbon stream containing acid gases, ethane and heavier hydrocarbon components. The substantially methane free hydrocarbon stream is thereafter passed through a semipermeable membrane system to separate the acid gases from the ethane and heavier hydrocarbon components.

A process of separating acid gases from hydrocarbons comprising separating methane from a hydrocarbon stream containing acid gases to produce a hydrocarbon stream substantially free from methane, and subsequently passing said substantially methane free hydrocarbon stream through a semipermeable membrane system to separate said acid gases from said hydrocarbon components, said acid gases passing through said membrane system at a substantially greater permeation rate than said hydrocarbon components. A process of separating acid gases from hydrocarbons comprising subjecting a hydrocarbon stream containing carbon dioxide and/or hydrogen sulfide to low temperature distillation to produce a hydrocarbon stream substantially free from methane, and subsequently passing said substantially methane-free stream through a semi-permeable membrane system to separate said acid gases from said hydrocarbon components and to produce a hydrocarbon rich stream, said acid gases passing through said membrane system at a substantially greater permeation rate than said hydrocarbon components.
