A METHOD FOR RECOVERING HYDROCARBON DILUENT FROM A POLYMERIZATION EFFLUENT CONTAINING SAME WHICH COMPRISES FLASHING SAID POLYMERIZATION EFFLUENT IN A FLASH ZONE, PASSING VAPORS THEREFROM TO A LOW PRESSURE WASH ZONE MAINTAINED AT ABOUT 18 P.S.I.A. AT 50*F., CONDENSING A PORTION OF SAID VAPORS IN SAID LOW PRESSURE WASH ZONE, REMOVING SAID CONDENSED VAPORS FROM A FIRST END OF SAID ZONE, CHILLING SAID REMOVED CONDENSED VAPORS TO ABOUT 15*F., RETURNING A PORTION OF THE CHILLED CONDENSED VAPORS TO A SECOND END OF SAID ZONE, PASSING THE UNCONDENSED VAPORS TO A KNOCK-OUT ZONE SO AS TO REMOVE LIQUID ENTRAINED THEREIN, COMPRISING THE LIQUID-FREE VAPORS TO ABOUT 80 P.S.I.A., COOLING THE COMPRESSED VAPORS, REMOVING ANY ADDITIONAL LIQUID FROM THE COOLED, COMPRESSED VAPORS, PASSING SAME AS FEED TO A HIGH PRESSURE ABSORPTION ZONE MAINTAINED AT ABOUT 75 P.S.I.A., REMOVING A PORTION OF THE CHILLED CONDENSED VAPORS FROM SAID LOW PRESSURE WASH ZONE, COMPRESSING THE CHILLED REMOVED PORTION TO ABOUT THE PRESSURE BEING MAINTAINED IN SAID HIGH PRESSURE ABSORPTION ZONE, INTRODUCING THE COMPRESSED, CHILLED LIQUID AS ABSORBENT IN SAID HIGH PRESSURE ZONE, CONDENSING A PORTION OF THE FEED TO SAID HIGH PRESSURE ZONE, RECOVERING CONDENSED LIQUID FROM SAID HIGH PRESSURE ZONE, REMOVING AND FLARING UNCONDENSED VAPORS FROM SAID HIGH PRESSURE ZONE AND SUBSEQUENTLY RETURNING THE RECOVERED LIQUID TO THE POLYMERIZATION SYSTEM.
