Demin Train Capacity
Demin Train Capacity
(OP)
I am wanting to use an ion exchange unit to
make 1180 tonnes/ hour of demin water and
polish 3200 tonnes/ hour condensate return.
How many trains am I going to require and who makes this for the Middle East.

Without a complete water analysis, it is hard to determine the volume of ion exchange resins required. However, you can estimate the size of the vessels based on the resin manufacturer's recommended hydraulic loading parameters. As a general rule service flow rate is typically 3 gallons per minute per cubic foot of resin and the typical resin bed depth is 36 - 48 inches. This rule applies only to makeup water only.
For condensate polishing, the hydraulic loading rate is typically 25 to 30 gallons per minute per square foot of plan area and the bed depth is 24 - 36 inches.
Since this site is not intended to be used for commercial purposes, please contact me through the web address below and I will share the name of an excellent company operating in the Middle East who can help you further.

How hot is your condensate? If you have a typical refinery condensate at 80-90 C you can't use a mixed bed desing without cooling it below 48.9 C.
One parameter that needs to be considered is the operating pressure of the steam generators and how much boiler blowdown you can tolerate.
