[Gasification] Question from Philip Pedros

Your question is really in several parts:
1. If you are referring to waste water containing sewage sludge, then
yes you will have the gas present.
2. Untreated Sewage gas (to clarify which syngas you are talking about)
cannot be fed directly into engines without at least a scrubber between
the gasometer storage and engine.
3. The gas calorific value of 120-150 Btu/scf is perfectly adequate to
run an engine and does not need boosting.
4. The technology you seek is already employed at many City Sewage
plants, generating power to run the plant.
5. I suggest you find working installations, there must be quite a few
in the USA.
Can I ask you why you or your organization think this is by your
question, unknown technology?
