<div>Dear Kevin,</div>
<div>currently the tar is used by villagers to smear wooden poles and tree trunks to protect them from termites. But huge quantities are also used in road construction. I think that the tar that is available in the market is a product of petroleum refining. Nobody in India uses any process aimed at retreiving tar from either the process of gasification or from charcoal making. When we started our experiments with distillation of agricultural waste, we found, that we were getting a lot of tar as a condensate. It was then that I started making inquiries about the possible use of the tar and discovered that there was a market for it. I don't even know if the tar obtained through our process would be useful in termite control or road construction. .<br>
Yours</div>

<div>Dear all,</div>
<div>tar is a valuable byproduct. Villagers buy it from a hardware shop at about US$1 per kg. So, we would prefer not to burn it. </div>
<div> </div>
<div><font size="2" face="Arial"># What do they use the tar for? What kinds of "tars" can tehy use, and for what purposes? Mpre specifically...</font></div>
<div><font size="2" face="Arial">1: Can they use the "blackwater" from gas scrubbing?</font></div>
<div><font size="2" face="Arial">2: Do they perhaps only use "whole tar" as would, for example, be produced by trapping tars from a charcoal retort?</font></div>
<div><font size="2" face="Arial">3: Do they perhaps only use a selected fraction of the "tar"</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial"># Your comments wil be very helpful.</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">Thanks.</font></div>

<div>Dear Doug, Brian and all</div>
<div><br></div>
<div>To what extent can you clean today's gas by passing it (cooled to about 150 C) through a barrel of tomorrows REASONABLY DRY fuel, thus permitting you to burn all the tars AND finish drying the fuel?</div>
<div><br></div>
<div>While a moisture content less than 20% is desirable for gasifier fuel, I suspect it should not be bone dry for long runs because it becomes autopyrolytic and won't retain a level pyrolysis zone.</div>

<div>Doug,</div>
<div><br></div>
<div>Oh goodness yes! We've not been willing to TOUCH the compression challenges until we got our gas pretty darn clean. I'm cautiously optimistic with where we are at on that task:</div>

<div><br></div>
<div>And right now we're planning on three separate compression steps with additional filters between each step.</div>
<div><br></div>
<div>And thanks for the pointer to your archives, I will certainly browse!</div>
