Patent ID: 8084013

Claim:
A method for the degasification of Claus-derived sulfur, the method comprising: a. Pumping liquid sulfur in a sulfur collection vessel through a gas-liquid eductor whereas the air inside the sulfur collection vessel is drawn into an eductor where it is intimately contacted with the pumped liquid sulfur; b. The two-phase mixture of air and sulfur leaving the eductor is further intimately mixed by passing the mixture through a static mixer; c. The two-phase mixture leaving the static mixer is directed to the bottom of the sulfur collection vessel where the mixture is discharged up through a layer of packing where further contacting is effected; and d. The air and sulfur separate as the sulfur reaches the top of the packed section whereas part of the air, containing the liberated hydrogen sulfide, is recycled back through the process through the gas-liquid eductor and the balance of the air is removed from the sulfur collection vessel through the use of a gas-gas ejector or blower.
