Forced Circulation Evaporators - Tubular Heat Exchangers For High Concentrate Efficiency | Zero-scaling, Enhanced Heat Transfer

Forced Circulation Evaporators

Forced Circulation Evaporators are tubular heat exchangers for concentrating a feed. An external mechanical agent is used to pump certain portion of concentrate back into the feed where it enters the evaporator. This approach has two basic benefits:

• Increased Heat Transfer: High concentrate to feed ratio is achieved as re-circulation increases the heat transfer coefficient of the feed. Also, the high velocities generated with the mechanical force ensure high heat transfer due to turbulence.
• Elimination of Scaling: The high velocities and low residence time achieved in a small space (due to high heat transfer) help to eliminate probability of feed reacting with the vessel and causing scaling.

Back to the Future
The detailed study of your process variables helps us design the right amount circulated feed to be introduced, and our experience in the process industry helps us to deliver re-circulation at the highest efficiency. The equipment is most suitable for crystalline feeds or those containing solids.

Shachi's expertise in energy efficient design delivers:

• High concentrate-to-feed ratio for the evaporator
• Easy to maintain systems due to zero-scaling
