Fire case validity for a tank in a remote location
Fire case validity for a tank in a remote location
(OP)
Hi folks,
I'm evaluating the need for fire sizing the PSV on a condensate tank that is located away (~1000 ft) from the general processing area. The closest source of a fire is 40 feet away. There are two other tanks that have their own containment. There are no other sources for a flammable pool of liquid to form / drain directly underneath the condensate tank. Any thoughts on whether liquid pool fire sizing would be a credible case?
Thanks.

Is it oily water?

The feed is coming off the high pressure dumps from the Amine, Dehy, and residue compressor systems. About 40% water, and the rest hexanes through decanes.

Liquid pool fire sizing is definitely a credible case.

To a ChE, the glass is always full - 1/2 air and 1/2 water.

No one knows what size the leak will be, so consider the possibilities and go with the worst credible case.

If you could model this on Hysis or Pro / II with the firecase relief utility, you'd get even lower vapor generation rates ( when compared to the old fashioned manual calc method).
