Oxygen spent acid regeneration

Figure 2.16 illustrates the process in the form of a flow diagram. When the H2S has been absorbed from the acid gas, the spent liquor, so to speak, from the absorber is fed to tiie reaction tank where the remaining H2S is oxidized K> elemental sulfur. The solution containing the suspended sulfur flows to the oxidizer where the semiquinone is re-oxidized to anthraquinone. A blower delivers air to provide the necessary oxygen. This air causes the sulfur to float up into a supernatant foam, which can then be skimmed off into the sulfur slurry tank. The regenerated solution flows to the pump surge tank to be pumped back to the absorber. [Pg.82]
