Industrial Applications That Power Long-Term Success

CLS Industrial Purification has designed and installed HCl, RCl, H2S, R-SH and Hg removal systems in over 600 reactor cycles worldwide based on our proprietary Variable Cell Zeolite technology, manufactured in Texas.

Our engineered manufacturing process combined with a systematic method of modeling, monitoring, and testing provides a result that is a measurable value for our clients in the form of decreased corrosion, lower maintenance costs, and better more reliable downstream operation.

Applications for CLS Vari-Zeo™ technology

Certified Purification from Offshore to Downstream

CLS provides certified purification in fixed bed absorbent applications across the entire energy vertical and is a trusted leader for the removal of key contaminants:

Chloride Removal

Absorption of organic and inorganic chlorides for Total Cl removal in gas or liquid phase Reformer (CCR) applications. No side reactions or green oils are made in the process.

Mercury Removal

Leading the oil and energy industry in the removal of element and organic mercury from raw natural gas and condensate upstream applications.

Sulfur and Arsine Removal

Absorption of mercaptanic, thiophenic, and benziothiophenic species for Total S removal in addition to absorption of organic and inorganic arsine. CLS S and Arsine guard beds purify gas or liquid phase streams in natural gas, refining, and petrochemical applications.

H2S Removal

Absorption of H2S and mercaptans from raw and condensate natural gas sweetening, refinery gas and liquids, and bio gas sweetening.
