    Thermal expansion relieve valves

    Dear georgeverghese All these PSV's goes to a Absorber column. Before i'm determining the plosses, I first need to calculate the scenario relief load.

    Thermal expansion relieve valves

    Dear Pierrick, Snickster Thanks a lot, both cases will give me a good calcuation method!

    Thermal expansion relieve valves

    Dear Pierreick Wong does indeed calculate the relieving volume. But how to further calculate the relieving flow in kg/hr?

    Thermal expansion relieve valves

    Dear all Although API 521 suggests that a nominal diameter of (DN) 20 × DN 25(NPS 3/4 × NPS 1) relief valve is commonly used for only thermal relieve scenarios because oversizing in this case is fine, I would like to calculate the 'exact' relieving flow and DP's for a thermal expansion PSV in...

    Cooling down of atm HCl from -60°C to -30°C

    Dear I would like to calculate how much meters of pipeline it takes to cool down HCl from -60°C to -30 °C in a pipeline using only air flow around it. The flow of HCl through the pipeline is 30000 kg/u. I took 3 m/s of wind at 20 °C. The pipeline is made of uninsulated stainless steel and is...
