Short Name
Let-down Valve (18)
Description

A trim heat exchanger (16), operating by using steam, hot oil or other high temperature fluid, further increases the temperature to a level suitable for liquid phase separation. The solution then passes through a let down valve (18) where a pressure drop is created, which causes the separation of the polymer solution and settlement into the lean phase 20 and a polymer rich phase 22 below it.
