Pressure spike due to flammable vapor combustion

[jalongo]

Pressure Vessel 75gal, Design pressure = 25psig
Ethyl Acetate, Flammablility limit 2% to 11.5%

It may be possible to misoperate the process and allow ethyl acetate and atmospheric air to combine in the pressure vessel. Assuming that the mixture of air and 11.5%EA vapor is created and somehow a ignition source is found...

How do I determine the increase in pressure due to the inadvertant combustion of EA vapor? Or at least determine the maximum impact on the design pressure of the vessel?

There's a useful article at

I could also send you a copy of a calculation that uses the "Cousins and Cotton" method.

You could also search the Web.
