When you say "gas", I assume you mean non-liquid.
If this is true, your incoming stream would be a dirty gas that contains solids, and you have no control over the quality of the incoming gas. Is this correct?
Maybe some other listmember has a solution. If not, I'll send it along to some R&D types I know.
