I thought Biomass gasification always produces tars in the gas, Which tnen have to be filtered out somehow.</span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: arial, helvetica, sans-serif; background-color: transparent; font-style:

<div><font face="Arial" size="2"><b>Hi Stuart,<br><br>In reply to Kevin you
ask:<br></b><br>So I wonder why there seems to be a general consensus that
dumping tarry water in a pond amounts to environmental vandalism. </font></div>

<div><font face="Arial" size="2"><b>Like gasifiers, unless you are specific as
to the process from which the condensate originates, it's like asking
about how long is a piece of string. Certainly not all condensates are toxic
black liquor, even if black, but some have benzene and other cacogenic
compounds which can permeate into the ground water. Some condensate does
kill plants, and I have made that stuff at times, in the past 36 years or so
during development projects ):-(</b></font></div>

it up. </font></div>

<div><font face="Arial" size="2"><b>Some of us have been around long enough to
have seen these sites, some 50-70 years old, where crude wood gasifiers once
powered irrigation schemes. The tar lakes are as toxic today as when they
formed, and the phenolic compounds leach to the run-offs in the wet
season.</b></font></div>

have better things to do than declare black water gasification leach ponds toxic

poor developing countries, are not aware or interested in how the power is made,
or what the operator does with his cooling ponds. The stink usually is enough to
warn you about these issues, but people including yourself, whom I assume
is well educated, need to be better informed of environmental issues regarding
condensate. We wave a red flag like the man walking in front of the first

responsible management is required. Water scrubbers draws our attention calling
for close scrutiny. No more, no less, hence, these interesting exchanges taking
