There are some relief valves that could be leaking by into the relief flare header. We are aware of visual observations of valve leakage for propane/propylene such as ice balls around the valves. Are there any suggestions for devices to measure severity of the leak?

A recent safety review was performed. Here is the scenario:
1000 gallon plastic tank containing amine
Positive displacement pump
If the vent were closed and the positive displacement pump (small pump, maybe a few gallons per hour)is running could it pull enough vacuum to damage the tank?

I need to calculate the available flow rate of instrument air to a control valve. The tubing is 3/8" SS and the pressure is 80 psig minimum. I do not know the velocity of the air or the pressure drop in the line so I'm having a hard time applying Bernoulli's. What assumptions/method should I use?
Hi, I'm planning on taking the PE Exam for chemical and I think I came across a great preparation course on DVD but the ad is in CEP magazine and I don't have a membership. Could someone please help me by telling me what this link is or sending me a copy of the information...
Has anyone else faced the challenge of getting pipe painted when noone wants to put $ in the budget?
First of all - does paint really matter on process piping?
Have there ever been any catastrophic incidents caused by corrosion due to a lack of painting/surface protection of the pipe? I...
I'm trying to calculate heat transfer from nitrogen to boiling water in a dryer system. N2 enters at a rate of 1400SCFM at 347K and 2psig and exits at 383K . I used the following link for N2 enthalpy data:
