Claim 1
Independent Claim
169 words
IN THE FRACTIONATION OF A SYNTHETIC CRUDE EFFLUENT OBTAINIED FROM A HYDROCARBON CONVERSION REATION, WHEREIN SAID EFFLUENT INFRACTIONATED BY INTRODUCING THE SAME AT LEAST PARTIALLY IN VAPOR STATE INTO A FRACTIONATING TOWER FOR SEPARTION INTO SEVERAL CUTS INCLUDING (A) A GASOLINE-CONTAINING CUT AND (B) A BOTTOMS PRODUCT HAVING A MID-BOILING POINT ABOVE 600*F., AND WHEREIN A PORTION OF SAID BOTTOMS PRODUCT IS COOLED AND ADMIXED IN LIQUID STATE FOR DIRECT HEAT EXCHANGE WITH THE HOT VAPOR EFFLUENT DIRECTED TO THE FRACTIONATINT TOWER; THE IMPROVEMENT WHICH COMPRISES INTRODUCING SAID PROTION OF COOLED LIQUID BOTTOMS AXIALLY INTO THE VAPOR CONDUIT CARRYING THE FLOWING STREAM OF SAID VAPOR EFFLUENT AT A LOCATION UP-STREAM OF SAID FRACTIONATING TOWER, SAID LIQUID BEING INTRODUCED BY DISCHARGING A CIRCUMFERENTIALLY EXPANDING CONE OF SAID LIQUID CONCURRENTLY INTO SAID FLOWING VAPOR STREAM, AND SAID LOCATION BEING SO SELECTED THAT THE EXPANDING CONE OF LIQUID DOES NOT CONTACT THE INNER WALL OF SAID CONDUIT ALONG A SUBSTANTIAL PORTION OF THE PATH OF FLOW OF SAID LIQUID TOWARD SAID TOWER.
