About Us

Total chloride removal systems with absorbent technology from CLS Industrial Purification result in measurable value for our clients.

Our innovative leading-edge absorbent technology is applied within engineered solutions, enabling oil refiners to achieve species specific trace contaminant removal. We are the only fully vertically-integrated absorbent manufacturer in the U.S.  

All of our absorbent technology and product systems are American made at our own Manufacturing Plant in Alvin, Texas 

With a goal of continuous improvement, dedication to technological advancements, and a committed focus on the customer, CLS Industrial Purification has designed and installed HCl, RCl, H2S, R-SH and Hg removal systems in over 600 reactor cycles worldwide. 

The result is a measurable value for our clients in the form of decreased corrosion, lower maintenance costs, and better more reliable downstream operation. 

CLS Chloride Absorbents:

• Engineered zeolites
• Absorb all inorganic and organic chlorides
• No side reactions that create more organic chlorides
• High capacity (30% wt equivalent)
• Work well at all temperatures
• Improved reliability by eliminating chloride-related problems

Traditional Chloride Absorbents

• Alumina-based or metal-oxides
• Absorb only inorganic chlorides. Organic chlorides slip to downstream users.
• All alumina-based absorbents make side-reactions that create organic chlorides that slip downstream.
• Low capacity (8-15% wt capacity)
• Metal oxides only work at temperatures >150C. Alumina-absorbents only work at temperatures <50C.
• Downstream salt formation, fouling, corrosion, catalytic impairments
