Ceramic support balls for sulfur production plants .
The Claus process is actively used at oil refineries, for processing hydrogen sulfide from hydrogenation plants and amine gas purification plants. The main task is to achieve 99.5% sulfur recovery without additional waste gas purification. Sulfur production plants convert H2S contained in acid gas streams from amine regeneration plants and sulfur-alkaline wastewater neutralization plants into liquid sulfur. Usually, the two or three-stage Claus process recovers more than 92% of H2S in the form of elemental sulfur
