Hello,
I am looking at designing an expansion tank for styrene monomer. I do not want a bladder type expansion tank, just one with an inert gas in it. It will be on a pumping line with a normal working pressure of 15 psig. It will composate for expansion whenever the line is blocked in (liquid full) and heated. I calculated that the volume increase at worst conditions will be 35 gallons. So I have two questions about this tank
-what volume should I add to the total capacity of the tank for nitrogen gas blanketing?
-I was going to add a nitrogen regulator and normally open line to the tank. What pressure would the regulator need to be set at? My calculation would be around 15-20 psig.
-how would I calculate the pressure in the vessel as liquid compresses the N2 in the tank? Is this necessary?
Thanks.
