Chloride Removal

Chloride Removal

  • CLS Revolutionizing chloride removal in oil refineries, CLS Industrial Purification provides absorbent systems featuring:
  • Vari Zeo - variable cell zeolite possessing a specific distribution of cell sizes and shapes selected for each application
  • Total Cl removal
  • Species specific Cl removal
  • Longer cycle lengths due to high Cl loadings of up to 44 wt% Cl at 66 lbs/ft3
  • Non-hazardous discharged spent absorbent making cost efficient disposal in class II land fill

This application is around the catalytic reformer (CCR) in oil refineries. HCl, λ-RCl and β-RCl are taken out from reformer 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 modelling 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. 

Benefits:

  1. Steam out during purging means no requirements for hot nitrogen 
  2. Faster purging times. 
  3. Free flowing spent material - much faster change out times. 
  4. Encapsulation of contaminants. 
  5. Spent product can be disposed of as Class 2 Non – Hazardous waste. 
  6. High activity means small mass transfer zone (mtz) leading to high bed utilization.

Downstream

CLS has enabled, through its Contaminant 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. Non-hazardous waste disposal.

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. 

Benefits of CLS Industrial Purification:

  • Total Encapsulation of the Contaminant
  • Eliminates Nitrogen Purging
  • Spent Absorbent is classified as Non-Hazardous Waste Class 2
