Hi,

I’m looking into installing a secondary heating/cooling loop for a glass-lined reactor and was wondering if anyone could share best practices or standard design documents for these systems.

For example, I’ve noticed that some oil-based systems (e.g DowthermJ) use magnetic pumps and plate-and-shell heat exchangers, while water/glycol systems typically use gasketed plate heat exchangers and pumps with single mechanical seals.

Is there a specific reason for this design philosophy, or is it mainly due to the fact that DowthermJ can be used at higher temperatures, thus requiring a more robust, high-containment design?

 

Any insight or general guidance/thoughts is much appreciated.

Hi,

A reference in the business:

Glass lined reactor manufacturer - Glass lined reactors - High pressure glass lined industrial reactor - Pilot plant scale glass lined reactor - GMM Pfaudler

 

You may want to contact them.

Can you describe what you mean "secondary loop"?

Seal system (magnetic or mech) depends on fluid properties, applications and local practices. You have shared none of them. Some guidance can be found in API 682 ann. A.
