Benfield Solution

[DanfromAisa]

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.

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.
