METHODS AND APPARATUSES FOR TREATING RAW NATURAL GAS COMPRISING A MEMBRANE UNIT AND A DISTILLATION

Techniques for treating a natural gas feed stream include receiving a natural gas feed stream that includes one or more acid gases, one or more hydrocarbon fluids, and one or more non-hydrocarbon fluids; circulating the natural gas feed stream to a membrane module; separating, with the membrane modu...

Zusammenfassung:	Techniques for treating a natural gas feed stream include receiving a natural gas feed stream that includes one or more acid gases, one or more hydrocarbon fluids, and one or more non-hydrocarbon fluids; circulating the natural gas feed stream to a membrane module; separating, with the membrane module, at least a portion of the one or more acid gases into a permeate stream and at least a portion of the one or more hydrocarbon fluids into a reject stream; circulating the permeate stream to a distillation unit; and separating, in the distillation unit, the one or more acid gases from the one or more non-hydrocarbon fluids. Cette invention concerne des techniques de traitement d'un flux d'alimentation de type gaz naturel comprenant la réception d'un flux d'alimentation de type gaz naturel qui contient un ou plusieurs gaz acides, un ou plusieurs fluides hydrocarbonés, et un ou plusieurs fluides non hydrocarbonés; la circulation du flux d'alimentation de type gaz naturel vers un module à membrane; la séparation, à l'aide du module à membrane, d'au moins une partie du ou des gaz acides en un flux de perméat et d'au moins une partie du ou des fluides hydrocarbonés en un flux de rejet; la circulation du flux de perméat vers une unité de distillation; et la séparation, dans l'unité de distillation, du ou des gaz acides du ou des fluides non hydrocarbonés.
