The present invention relates to a process for regenerating a rich MEG aqueous solution (), recovering a maximum amount of MEG while at the same time removing the carboxylic acid salts, including:

Method for regenerating an aqueous solution of MEG containing salts with purge treatment

The present invention relates to the extraction of gasoline from a gas G, with (a) a step of extracting gasoline from the gas to be treated comprising methanol GM obtained from step (d), (b) a step of separating said fluid GL1 partially condensed in step (a), producing (c) a step of contacting a portion of the gas G to be treated with said first aqueous liquid phase A1, producing (d) a step of mixing said gaseous phase of gas to be treated comprising methanol GM' with the remainder of the gas G to be treated, producing a gas to be treated comprising methanol GM, (e) a step of stabilizing said first liquid phase H1 of hydrocarbon(s).

Process for extracting gasoline from a gas containing condensable hydrocarbons

The present invention proposes to use a dry stream which is rich in C4 to C10 hydrocarbons as stripping agent for improving the regeneration of the liquid desiccant according to the invention. This dry stream rich in C4 to C10 hydrocarbons is extracted from the gas derived from the dehydration, for example during a step of extraction of NGL located downstream of the gas dehydration unit. The stream of stripping agent recovered at the outlet of the liquid desiccant regeneration unit may be recycled into the process of the invention or sent to a unit external to the process according to the invention. For example, this stream of stripping agent recovered at the outlet of the regeneration unit is sent to a unit which can receive wet condensates, such as a three-phase separation unit at the inlet of a crude gas processing plant, a condensate stabilization unit, etc.
