  • Process for treating a natural gas containing carbon dioxide
    Patent number: 11389764
    Abstract: A method for treating a natural gas containing carbon dioxide using membrane modules which are assigned to a first treatment stage or a second treatment stage and are fluidically connected to a retentate mode or a permeate mode. When evolution in the operating conditions results in one of the processing levels requiring less membrane surface for gas processing and the other processing level requiring more membrane surface for gas processing, then the method allows for reassignment of needed membrane modules assigned from one processing level requiring less membrane surface to another processing level requiring more membrane surface.
    Type: Grant

  • Method and unit for separating the light and heavy components of natural gas
    Patent number: 10627159
    Abstract: The invention relates to a method for the treatment of natural gas containing carbon dioxide, methane and paraffins. The method comprising: a step of extracting the paraffins from the natural gas in a paraffin-removal column, and a step of separating the carbon dioxide and the methane in a distillation column. The operation of the two columns being provided by means of the thermal coupling of said two columns using a thermal coupling heat exchanger.
