[Gasification] Producer gas. Dry cleaning.

[Oscar Jimenez]

Dear All.

Just recently I knew about the possibility of producer gas dry cleaning,
using " dolomite " on commercial basis. As far as I know the dolomite acts
as catalyst, getting the producer gas free of tar. The principle seems to be
rather well known, at least, such effect was known long ago. However I would
like to precise how commercial is it. 
Comments would be greatly appreciated.

Thanking you in advance.

Kindest regards.

Oscar.

i haven't seen one in person, but when we did the workshop in germany
they were highly spoken of and considered one of the most
accomplished.  the pictures have always looked impressive and the
company seems with lots of history and talent.  the price point seems
tolerable in germany, but a challenge for elsewhere.
