Abstract (en)
[origin: WO03100334A1] A two-column NGL recovery plant includes an absorber (110) and a distillation column (140) in which the absorber (110) receives two cooled reflux streams, wherein one reflux stream (107) comprises a vapor portion of the NGL and wherein the other reflux stream (146) comprises a lean reflux provided by the overhead (144) of the distillation column (140). Contemplated configurations are especially advantageous in a upgrade of an existing NGL plant and typically exhibit C>3< recovery of at least 99% and C2 recovery of at least 90%.
