Abstract
A method for recycling gas in an installation for the stabilization of crude oil (1) containing gas/liquid separation stages (2, 3, 4) whose gas removal pipes (12, 13, 14) are connected to the intake of a gas treatment installation (18) which provides a current of rich gas (19) and a current of poor residual gas (20), characterized in that an adjustable part (21, 22) of the poor residual gas current is injected into the flow of crude oil (8), preferably between the penultimate (3) and last (4) gas/liquid separation stage, of the installation for stabilization of crude oil (1), in order to increase the production of liquified petroleum gas and condensates.
