    Abstract: METHOD FOR REFRIGERATION OF A SULFURIC ACID ALKYLATION PROCESS OPERATED IN CONJUNCTION WITH AN ASSOCIATED ACID RECOVERY PROCESS INVOLVING REACTING USED ACID WITH OLEFIN FEED IN AN ABSORBER, EXTRACTING RESULTING DIALKYL SULFATES, ACID TREATING THE EXTRACT SOLUTION AND PASSING THE TREATED SOLUTION TO ALKYLATION. THE ACID TREATED EXTRACT SOLUTION IS VAPORIZED AND PASSED IN INDIRECT EXCHANGE WITH CONTENTS OF ABSORBER AND ALKYLATION REACTOR. VAPORIZED ISOBUTANE MAY BE SEPARATED, RECOMPRESSED, COOLED AND RETURNED AS A LIQUID FOR COMBINATION WITH THE ACID TREATED EXTRACT STREAM FOR ADDITIONAL COOLING CAPACITY.
