Dear Gasification Listserv and Biochar Listserv,<br>
<br>
The excellent comment by James Joyce (below) did not reach the
Gasification readers. It only went to the Biochar readers.
Interesting for two reasons (overly simplified, but to make a
point):<br>
<br>
1. Gasification for power (engines) is what causes the problem of
contaminated waste water, but those readers did not see the
"solution offered". THEY are the people who could test and evaluate
the solution.<br>
<br>
2. Biochar production (for agriculture and carbon sequestration)
has been proposed to make a filter-char that is to be burned, which
is what biochar production is trying not to do. That is, char as
filter for wastes made by trying to burn all of the biomass to ash.<br>
<br>
Those of us who are subscribed to both lists will see the full
discussion. Let's hope that this is a functional solution.<br>
<br>
(Of course it is better if the nasty contents in the waste water
were not created in the process of making the electro-mechanical
power.)<br>
<br>
To James Joyce, I say "Thanks."<br>
<br>

<p class="MsoNormal">Seems to me that the smallest foot print
treatment would be to filter the water through char, gravity
dewater and then dry the char to less than 30% moisture, then
combust it at over 1000 deg C in a chamber that maintains a 2
second residence time for the gases released from the
combustion. That will yield useful heat while destroying the
recalcitrant hydrocarbons. In locations with weather that does
not make solar or even bed drying viable, the process will
generate more than enough heat to run a heated air drier.<o></o></p>

such a process would probably only need to be run for a day a
week to treat scrubber water from storage tanks (i.e. never
put out to lagoons or open storage where it is of great risk
to the environment).<o></o></p>
