Abstract: PROCESS FOR OBTAINING IMPROVED REFRIGERATION RESULTS IN SULFURIC ACID ALKYLATION UTILIZING TWO ALKYLATION REACTOR: THE EMULSION OF ACID AND HYDROCARBON FROM ONE REACTOR IS FLASHED AND THE RESULTING MIXTURE IS SEPARATED INTO A COLD ACID PHASE AND A COLD HYDROCARBON PHASE. THE ACID PHASE IS USED TO COOL THIS REACTOR WHILE THE HYDROCARBON PAHSE IS COMBINED WITH THE REACTION MIXTURE FRM THE OTHER REACTOR TO PROVIDE TEMPERATURE REDUCTION. THE REACTION MIXTURE OF THIS REACTOR IS SEPARATED INTO ACID AND HYDROCARBON PHASES, THE ACID PHASE RETURNED TO SAID REACTOR AND PORTIONS OF THE HYDROCARBON PHASE IS PASSED THROUGH THE TUBE BUNDLES IN EACH REACTOR. PRESSURE REDUCTION PROVIDES EFFLUENT COOLING IN ONE OF THE REACTORS.
