Natural Gas Scrubber
Natural Gas Scrubber
(OP)
I am looking for a code which will provide the design specifications of a scrubber. Also, is there a scrubber requirement in case of Dry Natural Gas having dust particles?? Also, what is the pressure drop in a gas scrubber?





RE: Natural Gas Scrubber
Theoretically, there is no reason that you can't separate out physical particles from a gas stream in a separator the same way you do liquid droplets. In both cases, you are going to need to know the physical properties and the size of particles you want to remove, below a certain diameter the particles' settling velocity just become too low to practically settle them out using gravity. You might be better off with a physical filter to remove dust.
Pressure drop in a scrubber, too many variables. If you are talking about a conventional 2 phase separator with or without a demister pad you are talking a few inches of water typically (you can calculate it, you have an inlet and exit loss plus the pressure drop across the demister pad or other internals if you chose to install them). For a physical filter, the pressure drop is likely to be quite a bit higher. You can size a filter for whatever pressure drop you want but the lower the pressure drop, the more filter elements you need and therefore the higher the cost.

-Pressure vessel design - theres lots on this subject
-Process requirements: This is your requirements
You have to consider that a code cant take into account whats ownstream you vessel. There may be specific gas grid requirements wrt e.g. dust, liquids etc.
You could ask a typical vendor for a process data sheet template. This may guide you.
