Hi,

In our project, I have to decide requirement of Electric Heater in the Flare KO Drums and Closed drain drum. The viscosity range of fluds inside these vessels is from 1 cP - 5 cP (centipoise).

My understanding is we should be able to get the pump who can handle the this viscosity range and electric heater may not be required. Pump flow rate is 10 m3/h and differntial pressure is 8-10 bar. Density range is 700-900 kg/m3.

However, I seek suggestion from experts on this forum. Is this information available in any of the pump standards ?

Regards,
Shekhar

I don’t understand your need for an electric heater in the Flare KO Drum since you don’t cite any serious, low temperature of the pumped liquid.  I don’t see any problem with your liquid’s viscosity.  Perhaps your concerns are with its vapor pressure?  A heater would only lessen the viscosity – and possibly vaporize some liquid.

 

For this type of application, I have had success with turbine regenerative pumps.  Refer to the attached document that describes this type of pump – in case you are unfamiliar with it.  This is what I would recommend, but I would also advise you to carefully check with and consult with the pump fabricator on the application.

 

There are no pump standards, to my knowledge, that would make the pump selection for you.
