Description
The Claus process is used by the Sulfur Recovery Industry which converts hydrogen sulfide into elemental sulfur and water. The ”sour” natural gases have plenty of hydrogen sulfide within and if such gases are burned as fuel, Sulfide escapes, resulting in air pollution and damage to our tender environment. It has become an inevitable demand of mankind to convert maximum quantity of sulfur from ”sour” gas.
Activated Alumina is the most widely used Claus Catalyst which contains a large number of catalytically active surface sites that absorbs Hydrogen Sulfide (H2S ) and Sulfur Dioxide (SO2) for subsequent reaction to yield elemental sulfur.
In many acid gas streams, sulfur is present in various compounds such as H2S, COS, CS2, etc. Some of them may not be present in the feed gas but cumbustion of H2S in the presence of CO2 or hydrocarbons could result the formation of COS/CS2. These compounds must be converted to ensure proper sulfur conversion. Since the decomposition rate of these compounds are at lower rate than that of H2S/SO2 reaction, a highly active catalyst is required. Sulfation can be another problem as it reduces surface area and hence, the deactivation of catalyst.
We have developed highly efficient Claus Process Catalysts that will suit all these application.
•COS and H2S Conversion Catalysts
•Anti- sulfation Catalysts
•H2S Conversion Catalysts
•CS2 Conversion Catalysts
Our high performance Claus Catalysts are ideal for Claus units in natural gas plants, oil refineries, coke plants, tail gas units, etc.
