CLS has enabled, through its Chloride Monitoring Program (CMP), the management of chlorides whereby HCl and RCl are accurately tracked around the catalytic reformer circuit. The resulting Cl balance is real and demonstrates the effect of Cl removal, by species, in each part of the reformer circuit.

The latter, in chloride management, is now treated as one system with each Cl treater being an effective operating part of that system. For the first time oil refiners are able to plan and implement one overall Chloride removal strategy for their reformer circuit.

CLS Vari-Zeo technology performs contaminant (species of Cl, S and Hg) removal via an engineered zeolite lattice over 90% of which is internal to the absorbent particle. Stepping away from amorphous and bulk phase materials this allowed the industry to focus on contaminant absorption within the internal structure of the material. This breakthrough provided several benefits: Total chloride removal. Our total chloride removal systems are the only absorbents capable of removing 100% of HCl and RCl. Elimination of leaching risk. No matter what is done to the material while online, CLS Industrial Purification zeolites will not leach out Cl. Steaming is now a feasible means of clearing the vessel for discharge. There is no longer a need to use hot nitrogen.

Our systems can be discharged and disposed of as non-hazardous waste. Revolutionizing the chloride removal industry, CLS Industrial Purification provides systems 100% effective in removal – not transformation of contaminants - and longer cycle lengths, both environmentally friendly and cost efficient. In the reformer and isomerization circuits no two applications are the same. So CLS adopts a custom application-based approach meaning every system we install is custom designed and unique. No two systems are the same.

A kinetic model that describes in detail the proposed contaminant removal application is constructed. This assesses all process, reactor and kinetic parameters to predict performance of any absorbent system design proposed.
