What demister type to use
What demister type to use
(OP)
We have a gas stream that contains sticky particles/droplets that we need to remove. In separating the particles we don't want to loose too much pressure.
Options we have considered are:
1. Demisters (chevron plate type): Currently this option looks like the best option at this stage, because it will be cost effective and easy to install (it could be installed in our vertical knockout drum), but I am not sure what configuration to use.
2. Wire mesh demisters: The problem with these are that they could block very easily.
3. Cyclones:: This could work very well, but are very expensive. It could also have a high pressure drop.
Thank you very much!

RE: What demister type to use
You don't mention what the composition of the stream is or what the particles are made of, however one other thing to consider is spraying the mesh pad or plates with a solvent to wash the particles off of the pad or plate. You could make it a continuous spray or spray only when the pressure drop got too high.
RE: What demister type to use
The gas consists of CO, CO2, H2 and CH4. The water inside the gas consists of some tars and oils at 35 °C.
What I want to know is what TYPE of demister to use.
Thank you very much!
