Sulfur Rejection Units
Click any of the tabs above to learn more about the Natural Gas industry.
Overview
Sulfur Rejection Units (SRUs) are vital for many refining and natural gas operations. Environmental and regional regulations can require sulfur to be recovered before tail gas is flared to reduce the amount of sulfur polluted into the atmosphere. The recovered sulfur can be used for an array of different purposes including fertilizer additives or in the production of sulfuric acid.

A918 – alumina Claus catalyst
A918 is a hard working alumina catalyst that provides a high surface area for the conversion of hydrogen sulfide and oxygen to form sulfur and water in the Claus Process.
A958 – specially promoted Claus catalyst
A958 offers special capabilities in the SRU by increasing the hydrolysis of carbon disulfide and carbonyl sulfide into hydrogen sulfide.
A968 – titanium dioxide blend Claus catalyst
A968 is manufactured with titanium dioxide, which improves the hydrolyzation of carbon disulfide and carbonyl sulfide to reform hydrogen sulfide.
A988 – titanium dioxide Claus catalyst
A988 is specially manufactured with a high titanium dioxide content for maximized hydrolysis of carbon disulfide and carbonyl sulfide to reform hydrogen sulfide.
