A METHOD IS PROVIDED FOR REMOVING HYDROGEN SULFIDE AND HYDROGEN POLYSULFIDE COMPOUNDS OUT OF LIQUID SULFUR BY STRIPPING WITH A GAS, SUCH AS AIR. THE METHOD IS CONDUCTED IN AN APPARATUS EQUIPPED WITH AT LEAST TWO DEGASSING COMPARTMENTS (3,4) AND A SULFUR COLLECTION PIT WHEREIN THE DEGASSING COMPARTMENTS (3,4) ARE SEPARATED FROM EACH OTHER BY A FIRST PARTITION WALL (8), THE LAST DEGASSING COMPARTMENT (4) IS SEPARATED FROM THE SULFUR COLLECTION PIT BY A SECOND PARTION WALL (9) AND EACH DEGASSING COMPARTMENT (3,4) CONTAINS AT LEAST FIRST (6) AND SECOND SUBCOMPARTMENTS (18) WHICH ARE SEPARATED FROM EACH OTHER BY A THIRD PARTION WALL (7) AND ARE OPEN TO EACH OTHER AT THE TOP AND THE BOTTOM. AT LEAST ONE FIRST SUBCOMPARTMENT (6) IN EACH SAID DEGASSING COMPARTMENT (3,4) IS PROVIDED, AT THE BOTTOM THEREOF, WITH A PLURALITY OF STRIPPING GAS INLET NOZZLES AND AT LEAST ONE SECOND SUBCOMPARTMENT IN EACH SAID DEGASSING COMPARTMENT (3,4) IS NOT PROVIDED WITH STRIPPING GAS INLET NOZZLES. FURTHERMORE, SAID AT LEAST ONE FIRST SUBCOMPARTMENT (6) IS CONSTRUCTED FOR FLOWING LIQUID SULFUR OVER OR THROUGH THE FIRST PARTITION WALL (8) TO A SUBSEQUENT DEGASSING COMPARTMENT (3,4), THE LAST DEGASSING COMPARTMENT (4) IS CONSTRUCTED FOR FLOWING LIQUID SULFUR TO THE SULFUR COLLECTION PIT OVER THE SECOND PARTITION WALL (9) AND THE APPARATUS IS ALSO PROVIDED WITH A PROVISION FOR DISCHARGING GAS COMPRISING HYDROGEN SULFIDE |
