摘要: A two-column NGL recovery plant includes an absorber (110) and a distillation column (140) in which the receives two cooled reflux streams, wherein one stream (107) comprises vapor portion of other (146) lean provided by overhead (144) (140). Contemplated configurations are especially advantageous upgrade existing typically exhibit C3 at least 99% C2 90%.
