In the process of coal, petroleum and natural gas, a lot of H₂S is produced. In order to protect environment and recover sulfur, Clause process is widely applied for processing acid gases containing H₂S in industry.

According to many industrial applications of our sulfur recovery catalyst, the conversion rate of H₂S generally is 65-75%. Second-stage Clause technology ensures a rate of 92-95% while three-stage Clause technology leads to a rate of more than 98%.
