Dear All,

 

I have been looking for the heat exchanger configuration which can be used to cool high Viscous fluid (say 200-1000 poise). Please share your experiences and learning.

 

 

Thank and Regards,

Kamlesh

Kamlesh,

 

A static mixer heat exchanger in which the tubes are being inserted with static mixing elements will result in enhancing heat transfer rate for viscous fluids.

Depending on the temperature-viscosity behavior of process fluid, you may need to consider a closed-loop cooling system with controlled inlet temperature of the coolant to the heat exchanger. The coolant inlet temperature needs to be controlled in order to avoid flow problems on the high-viscosity fluid side of the exchanger, due to cold wall temperatures. Too low a temperature of the coolant may substantially decrease film temperature of the process stream, leading to extreme rise in viscosity, which will diminish heat transfer and promote other flow-related problems (fouling, plugging, under-deposit corrosion etc.).

Yes sir I have looked for this option. But the major problem is the increase in viscosity of material across the exchanger. It cures and clogs in the twisted surfaces.

Kamleshbagul,

 

I attached related information from "Heat Exchanger Design Handbook" of T. Kuppan, Edited by Marcel Dekker, New York, 2000.

 

Napo.
