Dear all,
I want to specify a flame arrestor on the vessel and need your help. See the details of the vessel below.
The main function of this vessel is to pull the vacuum from a reactor before, process starts.
During normal operation, this vessel collects water of about 900kg per batch however, occasionally, it pulls traces of solvent from reactor and hence a need for flame arrestor.
This vessel has 2” vent line and I want to specify an end of line flame arrester on this line.
Please note that we have a relief valve on a separate vent line of size 2” X 3”, set pressure 4barg.
As this is a pressure vessel and not an atmospheric tank, I am not sure, if can use normal inbreathing/outbreathing calcs for gas flowrate.
Size of vessel: 2m3
Location of vessel: within process building
Design vacuum : full vac
Design pressure: 7barg
Design temperature: 170deg
No insulation applied
Relief valve on a separate independent vent line is designed for a fire case
Thanks in advance for your help.
KS
