Abstract: 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 a first aqueous liquid phase A1, a first liquid phase H1 of hydrocarbon(s) a gaseous phase G1 obtained from the gas G; (c) a step of contacting a portion of the gas G to be treated with said first aqueous liquid phase A1, producing a second aqueous liquid phase A2, a gaseous phase of gas to be treated comprising methanol GM?; (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).

Abstract: The present invention relates to a process for regenerating a rich MEG aqueous solution (100), recovering a maximum amount of MEG while at the same time removing the carboxylic acid salts, including: a) vacuum evaporation of the solution (100) in a unit (1000); b) optional precipitation in a tank (1002) of the inorganic salts of a portion (105) of the liquid residue enriched in MEG and in salts (104) obtained from a); c) removal of the precipitated inorganic salts in a solid/liquid separation unit (1003); d) sending all or part (114) of the liquid effluent (112) obtained from c) into a separation unit (1004) different from the unit (1000) to form, notably, an MEG stream depleted in carboxylic acid salts or in carboxylic acids (115); e) recycling of said stream (115) into step a).

Abstract: 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.
