I have a gas flow through an 8" pipe into a 14" diameter cylinder over a length of approx. 16" then emerging into a pressure vessel. We have used similar configurations for the past 30 odd years. I have always used 7.5 degrees as the approx. half angle of divergence as the flow emerges from a...
We are designing a process unit that has a gas flow with the following composition : 14mol%CO2,84%CH4,the rest is Ethane, Propane, Butane and Pentane. The various lines operate at 75 barg with temperatures ranging from 50°C to 230°C with a water content of 0.2 to 1.7 mol% and a 1% vapour...
We have to select piping and valve materials suitable for a hydrogen gas stream containing 95 mol% H2, 2%N2, 3%CH4, 0.25%H2O, 0.1%CH3CN, 0.01%HCN, 50ppm NH3. Design conditions are 33 barg at 100°C. We design units for hydrogen gas streams on a regular basis using carbon steel piping and valves...
