Methods and configurations for improved propane recovery plant employ an absorber column, and a deethanizer column with an overhead condenser that produces a reflux condensate. The reflux condensate is recycled to both the absorber column and the deethanizer column, and a third recycling loop feeds propane from the absorber column into the deethanizer column in a gaseous form. The overhead condenser employs cold reject gas from the absorber and/or propane as a refrigerant, and preferred deethanizer columns include an integral water removal contactor. |
