Title (EN) METHOD OF PURIFYING A LIQUEFIED PETROLEUM GAS STREAM
(FR) PROCÉDÉ DE PURIFICATION D'UN FLUX DE GAZ DE PÉTROLE LIQUÉFIÉ
Abstract: front page image
(EN)The invention concerns a process for converting a contaminated liquefied petroleum gas (LPG) stream comprising C3 and/or C4, and further comprising from 80 to 20 mol% of dimethylether (DME) into a purified LPG stream, wherein the DME-contaminated LPG stream is fed to an oxygenate-to-olefin (OTO) process at conditions whereby the DME reacts to form olefins, and wherein purified LPG stream is obtained. Moreover, the invention concerns a system for producing oil and/or gas from an underground formation, including a well above the formation; a mechanism to inject an enhanced oil recovery formulation into the formation, and an oxygenate-to-olefin reactor.
(FR)L'invention concerne un procédé de conversion, en un flux purifié, d'un flux de gaz de pétrole liquéfié (GPL) contaminé comprenant des hydrocarbures en C3 et/ou C4 et comprenant également de 20 à 80 % en moles d'éther diméthylique (DME), le flux de GPL contaminé par le DME étant introduit dans un procédé de conversion de composés oxygénés en oléfines (OTO), dans des conditions auxquelles le DME réagit pour former des oléfines, permettant ainsi l'obtention d'un flux de GPL purifié. L'invention concerne en outre un système de production de pétrole et/ou de gaz à partir d'une formation souterraine comprenant un puits au-dessus de la formation ; un mécanisme d'injection d'une formulation améliorée de récupération de pétrole dans la formation, ainsi qu'un réacteur de conversion OTO.
