| description | A process and system for recovering natural gas liquids (NGL) using a combination of J-T cooling and membrane separation. The process involves compressing, separating, and cooling a flare gas stream comprising at least methane and C3+ hydrocarbons prior to being introduced to a J-T valve. The cooled stream exiting the J-T valve is further separated, producing a NGL product stream and an uncondensed gas stream. The uncondensed gas stream is directed to a membrane separation step, which results in a C3+ hydrocarbon enriched stream and a C3+ hydrocarbon depleted stream. The C3+ hydrocarbon enriched stream may be recycled back to the process to recover more NGL.
L'invention concerne un procédé et un système de recueil de liquides de gaz naturel (LGN) combinant refroidissement J-T et séparation membranaire. Le procédé implique de comprimer, séparer et refroidir un flux du gaz de torche comprenant au moins du méthane et des hydrocarbures en C3+ avant son introduction dans une soupape J-T. Le flux refroidi sortant de la soupape J-T est encore séparé, produisant un flux de produit LGN et un flux de gaz non condensé. Le flux de gaz non condensé est dirigé vers une étape de séparation membranaire, qui permet d'obtenir un flux enrichi en hydrocarbures en C3+ et un flux appauvri en hydrocarbures en C3+. Le flux enrichi en hydrocarbures en C3+ peut être recyclé et renvoyé dans le procédé en vue du recueil de davantage de LGN. |
