Within the refining and petrochemical industries, the removal of impurities plays a large part in catalyst efficiency and longevity.
Impurities, such as arsine, chloride and mercury, result in the poisoning of the catalyst and the corrosion of the steel equipment.
Our products can focus and remove the following Impurities:
Our broad product line and Trademark Layered-Bed Design Technology has the flexibility to provide optimal purification performance, even in the most severe environments. Severity of service and operating temperature, including trace removal for ultra-purification applications, are taken into consideration.
Multiple problems can be addressed in a single vessel. For the removal of sulfur, chloride species and other impurities from refining or petrochemical feedstreams, our trademark layered bed design technology matches our diverse line of purification absorbents and catalysts to the specific impurity type, concentration, temperature and other relevant purification conditions.

NSR-120RX is shipped prereduced and pacified for easy handling and startup.
UNICAT’s TSR-122E is the premier product for removing H2S in low temperature applications. TSR-122E utilizes a high concentration of Copper Oxide for maximum H2S absorption and will remove COS, CS2, and mercaptans. TSR-122E is ideal for light hydrocarbon and CO2 rich applications, both gases and liquids. TSR-122E will remove H2S down to ppb ranges.
UNICAT’s TSR-123 is a high absorption capacity copper-zinc-based absorbent for the removal of sulfur (H2S, COS, RSH), AsH3, and PH3 from both liquid and vapor phase hydrocarbon streams up to naphtha density. This product does not release CO2.
UNICAT's TSR-12SF is a specialty, bi-metal promoted, sulfur absorbent intended for the removal of trace H2S, COS, and light organic sulfur species. TSR-12SF is designed to meet some of the most stringent outlet sulfur specifications. TSR-12SF is intended for both gas and liquid applications at ambient temperature.
UNICAT’s TSR-12 is a high surface area copper impregnated activated carbon for bulk removal of sulfur species, especially H2S in vapor phase applications. Common applications include natural gas streams, refinery gases, and CO2 gas streams. TSR-12 is also regenerable.
UNICAT’s CLX-16E is a high capacity, promoted Zeolite for the removal of inorganic and organic chlorides in either gas or liquid applications such as natural gas, naphtha, refinery off-gas or light to medium range, liquid hydrocarbons. Additionally, during unloading, CLX-16E can withstand steaming without physical caking.
UNICAT’s CR-55 is a high-capacity, mixed metal oxide, hydrogen chloride removal absorbent. CR-55 is combination of calcium oxide and zinc oxide with a proprietary carrier for the removal of hydrogen chloride from all gases and light hydrocarbon liquids.

UNICAT's MR-15 is a high capcity copper sulfide absorbent on alumina support for the removal of trace elemental mercury. The captured mercury is chemically bound to the copper and thus the spent absorbent is very resistant to release the absorbed mercury. MR-15 is intended for both gas and liquid applications at ambient temperature.
UNICAT's MR-12 is a novel copper sulfide absorbent on coal-based activated carbon support for the removal of trace elemental and organic mercury. The captured mercury is chemically bound to the carbon and thus the spent carbon is very resistant to release the absorbed mercury.
