Products for Sulfur Recovery Units

Alumina SulCat – alumina Claus catalyst
Alumina SulCat 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.
Promoted SulCat – specially promoted Claus catalyst
Promoted SulCat offers special capabilities in the SRU by increasing the hydrolysis of carbon disulfide and carbonyl sulfide into hydrogen sulfide.
Blended SulCat – titanium dioxide blend Claus catalyst
Blended SulCat is manufactured with titanium dioxide, which improves the hydrolyzation of carbon disulfide and carbonyl sulfide to reform hydrogen sulfide.
Super SulCat – titanium dioxide Claus catalyst
Super SulCat is specially manufactured with a high titanium dioxide content for maximized hydrolysis of carbon disulfide and carbonyl sulfide to reform hydrogen sulfide.

Properties

Hengye Inc. manufactures a variety of products in its SulCat Series for use as Claus catalysts in sulfur recovery units. The Claus Process requires catalysts with specific properties to allow the recovery of sulfur from hydrogen sulfide (H2S).

Surface Area Hengye’s specialized Claus catalysts offer a highly active surface area, which allows H2S and oxygen (O2) to be converted to water and sulfur at efficient speed and conversion rates.

Physical Durability These products are strong enough to survive the rigors of the Sulfur Recovery Unit (SRU) furnace, while maintaining working ability to offer a long lifespan.

Particle Size Distribution A tightly controlled particle size distribution ensures excellent fluid dynamic flow properties in the SRU.

Overview

Sulfur Recovery Units (SRUs) are vital for many refining and natural gas operations. Many regulations 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.

How SRUs Work

In the Claus process, sulfur is recovered from H2S in Sulfur Recovery Units (SRU) and can be used for an array of purposes including fertilizer additives. Hengye offers multiple variations in its branded SulCat Series of Claus catalysts to suit the needs of our users, depending on environmental requirements and feed composition. Alumina SulCat can be used for recovery of sulfur from H2S. Promoted SulCat, Blended SulCat, or Super SulCat can be used to recover sulfur from H2S while also converting COS and CS2 into H2S to further remove the presence of sulfur from the stream.
