<p>Hi Philip,</p>
<p>Your question is really in several parts:</p>
<p>1. If you are referring to waste water containing sewage sludge,
then yes you will have the gas present.</p>
<p>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.</p>
<p>3. The gas calorific value of 120-150 Btu/scf is perfectly
adequate to run an engine and does not need boosting.</p>
<p>4. The technology you seek is already employed at many City
Sewage plants, generating power to run the plant.</p>
<p>5. I suggest you find working installations, there must be quite
a few in the USA.</p>
<p>Can I ask you why you or your organization think this is by your
question, unknown technology?</p>
<p>Regards,</p>
<p>Doug Williams.<br>

<p class="MsoNormal">Can untreated syngas generated from
municipal wastewater sludge be used directly to generate
power? It is my understanding that the heating value of
untreated syngas (120 – 150 But/scf), is too low to feed
directly to engines and that some type of post treatment to
boost the heating value to 190 -200 is typically economically
prohibitive. Any information on such post treatment and an
case studies were this has been done would be appreciated.<o:p></o:p></p>
