[Gasification] compression of dirty gas

[praufast at free.fr]

"After a few hundred hours the compressor would look like the inside of a woodstove chimney.  It would be out of balance, shaking and there would be a toxic waste disposal problem.  The acids in the woodgas would also eat into the aluminum rotor.  Conceptually, a decent idea though.

The water is continually recirculated and cooled, obviously it can also be cleaned or replaced with fresh water.
To clean it you can use something like a Voraxial separator : http://www.youtube.com/watch?v=-W8_GpMz9nI&feature=related
