By mining the operating data of a light hydrocarbon recovery plant, a new production plan has been proposed to optimize the refrigeration system, which is evidenced to improv.

study on natural gas membrane light hydrocarbon recovery technology;

Discussion on methods of light hydrocarbon recovery during imported crude oil distillation;

Ejector technology used in oil field in light hydrocarbon recovery;

In this paper, according to the problem of C_3 recovery rate is not high in a NGL recovery plant with turbo-expander, the main unit process models were built up, and the process simulation calculation is taken .

According to this, reasonable reform suggestions are put forward so as to lower inter-stage pressure fall, raise the air admission amount of compressor and ensure the stable running of light hydrocarbon device
