Specializing in chloride removal and sulfur removal, CLS Industrial Purification understands no two Cl treaters or sulfur guards are the same and offer custom-made absorbent systems.

Absorbents

CLS Industrial Purification absorbents are used in polishing beds and spike guards:

• Polishing Beds
Focus mainly on removal of S and Cl species to equilibrium levels
• Spike Guards
Focus on accommodating S and Cl spikes, while protecting against other contaminants

Chloride Removal

This application is around the reformer (CCR) in oil refineries. HCl, λ-RCl and β-RCl are taken out from H2 gas and reformate liquid. CLS Industrial Purification produces zeolite-based absorbents that can remove all Cl species without forming green oils and RCl.

Through kinetic modeling of Cl treaters, CLS Industrial Purification can accurately predict cycle lengths, given differing contaminant levels. Accurate measurement of RCl in H2 gas can be performed via onsite Cl survey, leading to accurate Cl balance around the CCR.

Custom-Made Absorbent Systems

No two Cl treaters are the same. The most important differences are:

• Cl species and their ratios
• Type and extent of contaminant causing early die off

CLS Industrial Purification offers layered absorbent systems that deal with reactor-specific Cl duty. Our custom-made absorbent systems are:

• Zeolitic base using base metal (Ni, Cu and Zn) additives for removing thiophenic sulfur, mercaptanic sulfur and H2S
• Zeolites - fixed cell, variable cell and exo type
• Aluminas – activated and different levels of promotion
• Mixed-metal oxides
• Fixed-cell zeolites
• Variable-cell zeolites
• Exo zeolytes
• Sulfur Removal

This is applied to the reformer feed and isomerization unit feed in oil refineries.
