< 20 mg/Nm3 by water washing.<br>
<br>
Waste water is then treated by both physical (decantation) and
biological (using bacteria to decrease COD) processes.<br>
<br>
After the treatment of this waste water, the water is re-used in
the process, and "final tar" is landfilled.<br>
<br>
I have some recent government reports or Chinese papers about
the situation of gas fuel stations, but in Chinese.<br>
<br>
I am preparing a presentation about the gasification status in
china for a conference in Germany, but the powerpoint is not
ready.<br>
<br>
I can upload a powerpoint and send to the list a link for
download after the conference.<br>
<br>
Hope this information is useful for you.<br>

<pre wrap="">LI>In China, there are hundreds of villages using fuel gas
station...(gasifier --> producer gas --> pipe line --> end user).
Li,
Is this producer gas from wood gasification or biogas from anaerobic
digestion?
We hear about the large number of anaerobic digesters in China but I have
never seen evidence that wood or straw gasifiers are used in anything larger
than a household.
