What advantages does LO-CAT have treating Claus Tail Gas?

LO-CAT’s primary advantage is in retrofitting existing Claus units that are being forced to meet tighter emission limits. The LO-CAT unit would be new capacity, so it would not require debottlenecking of the existing Claus unit. In addition, the LO-CAT unit can treat the sour waterstripper gas, improving Claus operation and freeing up existing capacity in the Claus unit, and/or be sized to provide redundant capacity for the Claus unit.
