Benfield Solution

Benfield Solution

Benfield Solution

(OP)
I need to size a control valve for the above fluid. For doing so I need from you information about vapor pressure, critical pressure, chemical composition.
Viscocity 0.74 CP and specific gravity 1.249 have been given.
Your help will be very much appreciated.  

RE: Benfield Solution

     Just some more information about "Benfield Solution": that is a mix of potassium carbonates, diethylamine and vanadium, which is used for removal of CO2 (typically in the production process of ammonia); it may form foam, but becomes solid when temperature decreases...

     Stainless steel and graphite are usually suitable for such a service, but risks of erosion and sticking must be also considered.
