Designing 2-phase Vertical separators

[Optimustang]

Hello folks,

I am new to this area of designing pressure vessels. I want to learn/know the procedure to design a vertical separator vessel which sits upstream of every stage in a compressor. I know it depends on the gas velocity and resident time of the gas in the vessel, but I don't know how to calculate them and put them to use.

Any help will be greatly appreciated.

Thanks,

In specific, I am talking about compressor interstate SCRUBBER (or Knockout) vessels, which handle mixtures with very high gas-to-liquid ratios and have small amount of liquid collection.

I have never seen a 3-phase interstage scrubber. In an interstage scrubber we want to get rid of the liquid that condensed and the mix of liquid water and liquid hydrocarbons is just to variable to successfully separate it on-skid. If I'm worried about condensable hydrocarbons in the interstage I'll dump the scrubber to a gun barrel that has a much better chance of successfully handling is than a 5-second retention period vertical scrubber.

What would you be doing, if you knew that you could not fail?
