Our Technology

CLS Industrial Purification designs and manufactures custom-made absorbent technology systems.

One absorbent system goes into one reactor charge. One reactor charge is made up of several layers of variable zeolites. The cell shape and size distribution of each zeolite layer specifically removes the range of Cl and S species desired. The ratios between the layers and the actual cell size shape and distributions are changed within a 3- or 4-cycle period. This is necessary in order to achieve the system that optimally removes that specific cocktail of Cl or S species contained in the feed.

Each absorbent system is therefore specific to each reactor. Every reactor charge is like an individual and cannot be replicated for use in another reactor. CLS Industrial Purification does not make a family of products, but rather creates individual reactor loads, each with a unique "recipe."

Designing and producing our own material allows us to continually alter and improve these "recipes" to achieve optimal chloride balance for each reformer circuit.

Advantages of Manufactured Absorbents from CLS Industrial Purification

• Total chloride removal
• No green oils 
• No RCl formation 
• Non-hazardous when spent 
• Can be steam-discharged in one day
• Reduced pressure drop
• Small Mass Transfer Zone
 (High Average Chloride Removed)

Reformer Cl Balance

A typical CCR Cl balance is shown in the diagram, indicating the Cl treater (bypassed) positions. Each point of the reformer circuit has its own specific total Cl level and mixture or cocktail of Cl species that are affected by:

• Perc injection rate
• CCR operation
• 1st stage pressure
• 2nd stage pressure/temperature
• Reformate/H2 flow rates
• Performance of Cl treaters

When it comes to Cl management, the reformer circuit is one interdependent system. Each Cl treater should be operated as part of that system, within one overall chloride removal strategy for the reformer circuit. 

CLS Industrial Purification designs zeolite absorbent systems that remove specific Cl species for specific reformer circuit streams.
