METHOD OF EXTRACTING PROPANE WITH HIGH DEGREE AND TECHNOLOGICAL SCHEMES

摘要

The gas processing plant includes an ethane reflux column (106) and an absorber with irrigation (103), while the absorber (103) operates at a higher pressure than the ethane reflux column (106), and at least part of the residual product (7) of the absorber is expanded for ensuring cooling of the reflux flow of the absorber and / or the flow of raw materials for the distillation column. Particularly proposed gas processing plants include propane and ethane extraction units, and in cases where the gas processing unit is an ethane extraction unit, it is envisaged that the ethane product contains no more than 500 ppm of carbon dioxide. The international application was published with international search report.
