  • Process of separating acid gases from hydrocarbons
    Patent number: 4374657
    Abstract: 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.
