Fremgangsmåte og system for gassfraksjonering ved höyt trykk
Process allowing to fractionate a gas, wherein:the gas is cooled from T0 to a temperature T1,at least part of gas phase G1 is sent to an expansion stage (X1) in order to obtain a mixed phase M2 at a temperature T2 and at a pressure P2,mixed phase M2 is sent to a heat exchange stage where it serves a...

Summary: | Process allowing to fractionate a gas, wherein:the gas is cooled from T0 to a temperature T1,at least part of gas phase G1 is sent to an expansion stage (X1) in order to obtain a mixed phase M2 at a temperature T2 and at a pressure P2,mixed phase M2 is sent to a heat exchange stage where it serves as a cooling agent, and after which it is heated,liquid phase L1 is sent to an expansion stage,the heated mixed phase and the expanded liquid phase are sent to a separation stage so as to obtain a gas phase and a liquid phase, andthe gas phase is fractionated by distillation performed by means of continuous heat exchange with mixed phase M2, and the light constituents are extracted as gas and the heavy constituents as condensates, the fractionation stage being performed after the stage of expansion of mixed phase M2. |
