Dear Members
I am trying to find out the vapor nozzle connection to the propane pressure vessel coming from a rail car.
I have "n" number of rail cars unloading propane to "K" number of pressure vessels of propane.
My question is the vapor return during warm conditions saturated at 160 psig from rail cars through the 3 way valve to compressor which will fill the propane pressure vessel.s
Should the vapor return that sucks out the remaining propane from rail cars there by reducing the pressure at rail cars to fill in the pressure vessels be connected from bottom or top.
Here is the figure for review
Also how can i calculate the cooling time from Discharge pressure of compressor to ambient temperature of the pressure vessel, Please let me know .Thank you
