Hi,
I was wondering if someone could give their thoughts on the following.
I have calculated the back pressure on a steam relief valve on the discharge side of the valve. The relief valve is 4" x 6" relief valve with a set-point of 58 barg and rated capacity of 69,000 kg/h at 410 deg.C inlet...
I have two quick questions (or sanity checks).
1. Am I correct in thinking that pipework, silencers etc on the discharge side of a relief valve should be sized using the un-derated flow of the relief valve and NOT the derated flow?
2. When the relief case is from a single pressure reducing...
Hi,
Are there gas compressors on the open market (UK if poss) that can fulfil the following duty.
Inlet pressure: ~20 mbarg
Oulet pressure: 2,000mbarg
Flow: 2,500 Nm3/h
Fluid: off gas (51% N2, 18% CO, 12% CO2, 17% H2, 2% CH4)
Inlet temperature 500 deg.C
Thanks in anticipation of a quick...
DOes anyone know of other technologies for mercury removal other than adsorption. We are looking to install mercury removal equipment after an NGL liquid feed dehydrator and before the de-ethaniser tower. The design conditions are roughly:
Flow = 300m3/h
Pressure= 30-35barg
Temperature=...
I am currently designing a relief valve discharge pipework for a steam line. Please could someone tell me if the following is true:
The flowrate used for the discharge pipe sizing should be at least the Certified Discharge Capacity of the relief valve (I know some would use the un-derated...
Has anyone had any experience in sizing steam traps after a desuperheating station on steam lines. My logically thinking is that the trap (or traps) should be sized to drain water that may be inject by the spraywater system as follows:
1. As in our case the steam flow is not constant and there...
