Hi, I'm designing my own refrigeration system (NH3) where currently on designing the separator/receiver. I am familiar with pressure vessel and heat exchanger sizing but that as a mechanical engineer scope. Now, I need to do sizing and study of the V/L separator downstream of the expansion valve.
The downstream of expansion valve discharged about 15% NH3 vapor so when it gets into the separator I only wanted the liquid NH3 going into my evaporator.
Inlet pressure of the separator is about 2.87 bara, weird enough on the simulation program (I used Petro-SIM which is similar to HYSYS) the outlet pressure of both liquid and vapor stream maintains the same as inlet BUT i know I have to input the pressure drop (which must be known).
How do I find out how to calculate the pressure loss across my separator provided I know the diameter and height of the separator/receiver? Some website suggested to calculate using PIPE SEGMENT in the simulation program but the issue is that the program cannot calculate more than two outlets
Anyone had any brilliant idea around this? Thanks
