Method for reducing sulfur compounds in sulfur plant effluent
Abstract
Abstract IN THE RECOVERY OF SULFUR FROM HYDROGEN SULFIDE-CONTAINING GASES WHEREIN THE FIRST OF A SERIES OF REACTORS IS OPERATED UNDER CONVENTIONAL CLAUS CONDITIONS, ONE OR MORE OF THE REMAINING CATALYTIC REACTORS IN THE SULFUR PLANT ARE OPERATED AT TEMPERATURES OF THE ORDER OF FROM ABOUT 250* TO ABOUT 400*F. WHEREBY FREE SULFUR IS DEPOSITED ON THE CATALYST, REGENERATION OF SUCH CATALYST IS EFFECTED BY HEATING A PORTION OF THE FIRST REACTOR-CONDENSER EFFLUENT TO 500*-700*F. AND FLOWING THE RESULTANT HOT GAS THROUGH THE DEACTIVATED CATALYST BED TO VAPORIZE FREE SULFUR THEREFROM AND REGENERATE THE CATALYST. BEFORE PLACING THE FRESHLY REGENERATED CATALYST BED BACK ON STREAM, IT IS COOLED WITH UNHEATED FIRST REACTOR-CONDENSER EFFLUENT TO A TEMPERTURE OF FROM ABOUT 250* TO ABOUT 400*F. THEREAFTER THE ABOVE CYCLE IS REPEATED.
