I have been given the task of calculating how many pounds of H2S was released through a pressure relief valve on a slop tank that was constantly fed a supply of gas for a 24 hr period. I wish I was a ChemE, but I'm not, so I would appreciate some help from someone who is.
The slop tank holds 400 barrels and is ~20' high and ~10' in diameter. For this exercise, let's assume that it is 1/2 full of liquid. It has 2 PRV's one is set at 8 psi and the other, a trap door, is set at 16 psi. The 8 psi valve was opened and flowed to atmosphere through a 3" ID vent pipe. The pipe is ~3 ft long. The trap door was not opened. The gas that is being released contains 6.5% H2S.
For this calculation, I will assume that the gas supply was steady and kept the tank pressurized at 8 psi.
I am attempting to calculate how many pounds of H2S are being released per hour. Thank you in advance for your assistance.
