Used for the recovery and treatment of hydrogen sulfide-containing gases emitted from laboratories
The Claus process makes use of hydrogen sulfide in gases; it is partially oxidized in a Claus burner to produce sulfur dioxide, which then reacts with more hydrogen sulfide to yield sulfur. The main reactions are as follows: H2S + 3/2 O2 → SO2 + H2O + 518.8 kJ; 2H2S + SO2 → 2H2O + 3/2 S2 + 146.4 kJ. This process is used to purify exhaust gases by removing sulfides and recover sulfur, and it is widely applied in industry. There are more than 20 specific processing methods, and different approaches can be chosen according to the actual circumstances in order to control sulfide pollution.
It should be the gas flow rate and the levels of hydrogen sulfide and other substances.
