Commingling separated liquids with a gaseous feed mixture resolved by liquefaction

Claim 1

A METHOD FOR SEPARATING HIGHER BOILING CONSTITUENTS FROM A FEED STREAM OF A MIXTURE OF GASEOUS COMPONENTS WHICH COMPRISES: (A) IN A FIRST STAGE TREATING ZONE, UNDER TEMPERATURE AND PRESSURE CONDITIONS WHICH EFECT A LIQUEFACTION OF AT LEAST A PORTION OF SAID HIGHER BOILING CONSTITUENTS, COMMINGLING SAID GASEOUS FEED MIXTURE WITH A LIQUID CAPABLE OF ABSORBING AT LEAST A PORTION OF SAID HIGHER BOILING CONSTITUENTS THEREFROM, (B) COOLING THE GAS-LIQUID MIXTURE RESULTING FROM SAID FIRST STAGE COMMINGLING STEP TO REMOVE HEAT EVOLVED IN THE ABSORPTION BY SAID COMMINGLE LIQUID OF CONSTITUENTS FROM SAID GASEOUS FEED MIXTURE TO PROVIDE A FIRST STAGE GASEOUS EFFLUENT HAVING A REDUCED CONTENT OF SAID HIGHER BOILING CONSTITUENTS AND A FIRST STAGE LIQUID EFFLUENT ENRICHED WITH SAID HIGHER BOILING CONSTITUENTS, (C) SEPARATING SAID FIRST STAGE GASEOUS EFFLUENT AND SAID FIRST STAGE LIQUID EFFLUENT, (D) IN A SECOND STAGE TREATING ZONE, UNDER TEMPERATURE AND PRESSURE CONDITIONS WHICH EFFECT A LIQUEFACTION OF AT LEAST A PORTION OF THE REMAINING SAID HIGHER BOILING CONSTITUENTS, COMMINGLINGG SAID FIRST STAGE GASEOUS EFFLUENT WITH A LIQUID CAPABLE OF ABSORBING AT LEAST A PORTION OF THE REMAINING HIGHER BOILING CONSTITUENTS THEREFROM, (E) COOLING THE GAS-LIQUID MIXTURE RESULTING FROM SAID SECOND STAGE COMMINGLING STEP TO REMOVE HEAT EVOLVED IN THE ABSORPTION BY SAID LIQUID EMPLOYED IN SAID SECOND STATE COMMINGLING STEP OF CONSTITUENTS FROM SAID FIRST STAGE GASEOUS EFFLUENT TO PROVIDE A SECOND STAGE GASEOUS EFFLUENT HAVING A FURTHER REDUCED CONTENT OF SAID HIGHER BOILING CONSTITUENTS AND A SECOND STAGE LIQUID EFFLUENT ENRICHED WITH SAID HIGHER BOILING CONSTITUENTS, (F) SEPARATING SAID SECOND STAGE GASEOUS EFFLUENT AND SAID SECOND STAGE LIQUID EFFLUENT, AND (G) PASSING SAID SECOND STAGE LIQUID EFFLUENT TO SAID FIRST STAGE TREATING ZONE AND COMMINGLING SAME IN SAID FIRST STAGE COMMINGLING STEP WITH SAID GASEOUS FEED MIXTURE.

Claim 2

A METHOD FOR SEPARATING HIGHER BOILING CONSTITUENTS FROM A FEED STREAM OF A MIXTURE OF GASEOUS COMPONENTS WHICH COMPRISES: (A) IN A FIRST STAGE TREATING ZONE, UNDER TEMPERATURE AND PRESSURE CONDITIONS WHICH EFECT A LIQUEFACTION OF AT LEAST A PORTION OF SAID HIGHER BOILING CONSTITUENTS, COMMINGLING SAID GASEOUS FEED MIXTURE WITH A LIQUID CAPABLE OF ABSORBING AT LEAST A PORTION OF SAID HIGHER BOILING CONSTITUENTS THEREFROM, (B) COOLING THE GAS-LIQUID MIXTURE RESULTING FROM SAID FIRST STAGE COMMINGLING STEP TO REMOVE HEAT EVOLVED IN THE ABSORPTION BY SAID COMMINGLE LIQUID OF CONSTITUENTS FROM SAID GASEOUS FEED MIXTURE TO PROVIDE A FIRST STAGE GASEOUS EFFLUENT HAVING A REDUCED CONTENT OF SAID HIGHER BOILING CONSTITUENTS AND A FIRST STAGE LIQUID EFFLUENT ENRICHED WITH SAID HIGHER BOILING CONSTITUENTS, (C) SEPARATING SAID FIRST STAGE GASEOUS EFFLUENT AND SAID FIRST STAGE LIQUID EFFLUENT, (D) IN A SECOND STAGE TREATING ZONE, UNDER TEMPERATURE AND PRESSURE CONDITIONS WHICH EFFECT A LIQUEFACTION OF AT LEAST A PORTION OF THE REMAINING SAID HIGHER BOILING CONSTITUENTS, COMMINGLINGG SAID FIRST STAGE GASEOUS EFFLUENT WITH A LIQUID CAPABLE OF ABSORBING AT LEAST A PORTION OF THE REMAINING HIGHER BOILING CONSTITUENTS THEREFROM, (E) COOLING THE GAS-LIQUID MIXTURE RESULTING FROM SAID SECOND STAGE COMMINGLING STEP TO REMOVE HEAT EVOLVED IN THE ABSORPTION BY SAID LIQUID EMPLOYED IN SAID SECOND STATE COMMINGLING STEP OF CONSTITUENTS FROM SAID FIRST STAGE GASEOUS EFFLUENT TO PROVIDE A SECOND STAGE GASEOUS EFFLUENT HAVING A FURTHER REDUCED CONTENT OF SAID HIGHER BOILING CONSTITUENTS AND A SECOND STAGE LIQUID EFFLUENT ENRICHED WITH SAID HIGHER BOILING CONSTITUENTS, (F) SEPARATING SAID SECOND STAGE GASEOUS EFFLUENT AND SAID SECOND STAGE LIQUID EFFLUENT, AND (G) PASSING SAID SECOND STAGE LIQUID EFFLUENT TO SAID FIRST STAGE TREATING ZONE AND COMMINGLING SAME IN SAID FIRST STAGE COMMINGLING STEP WITH SAID GASEOUS FEED MIXTURE.
