<pre style="font-size: 9pt;"><tt>Thanks for your input Artem and Leland. <br>
<br>
Leland we are working from a source separated feedstock ... but of course no <br>
separation method is every perfect. As far as air toxics I think I will start <br>
with the argument that if we get below the detection limit for a given species <br>
when using good quality industrial analysers (not research lab instruments) then <br>
our job is done. <br>
<br>
On a related note we normally use CO as an operational performance indicator for <br>
all hydrocarbon derived compounds... in our systems it is by far the most <br>
prevalent residual gas species and in my experience is that is the last compound <br>
(apart from soot) to be oxidised completely in a biomass flue gas ... is that <br>
the experience shared by others ? <br>
<br>
One aspect we may have to face is questions about dioxins. We do all the right <br>
things to avoid formation in terms of feedstock selection and operating <br>
temperatures/residence times ... however we have not done actual measurements. I <br>
am told that Dioxin measurements are around $3000/analysis in Australia ... is <br>
that the case elsewhere ? That makes performance data collection <br>
prohibitively expensive. What are others doing for Dioxin analysis ? <br>
<br>
Artem, bag filtering at 600 deg C is interesting ... it keeps you well above the <br>
Dioxin formation temperature range ... I could not see much detail on your site. <br>
Can you provide any more information on this ? Are you referring to Cerafume <br>
bags like those described here: <a target="_blank" href="http://www.albkleinco.com/cerafume-high-temperature-gas-filters/">http://www.albkleinco.com/cerafume-high-temperature-gas-filters/</a> <br>

Dear Sirs, <br>
<br>
It is a really interesting discussion. I haven?t written yet. But I want to <br>
share with all of you information regarding a fumes treatment part. As you can <br>
see in signature the company name we deal with fumes treatment units. We work <br>
mainly in renewable energy field such as gasification offering our systems to <br>
clean the fumes. This is our main archived goals: <br>
<br>
- Bag filtering systems, emissions < 1mg/Nmc, flue gas flow temperature 600 <br>
?C; <br>
- A unique filtering system to DeDust ? DeNOx ? DeSOx, direct dedusting <br>
at temperature 350 - 400 Celsius degree; <br>
- Heat recovery systems. <br>
<br>
Please be free to contact me for any issue, <br>
<br>
<br>
Best regards, <br>

<br>
This standard is not uncommon and most of it is just verbiage to <br>
cover as many sources as possible. If below detection limit, or not in the input <br>
gas, then it complies. The measurement is very expensive using standard US EPA <br>
<br>
methodologies, but there is equipment that can be used to detect below the <br>
standard methods of analysis and costs around the same cost as one comprehensive <br>
gas analysis, which could be <br>
<br>
$35-60k in US terms. <br>
<br>
The best way to comply is to remove as many of the contaminants as <br>
possible before the fume incinerator or flare. I can go into more detail, and <br>
indeed there may be a very inexpensive way of complying <br>
<br>
if they would accept it, but I don't do it for free. <br>
<br>

<br>
Some questions for the group. We have been asked to comply to the following <br>
regulation regarding operation of our thermal oxidiser. My questions are: <br>
<br>
1. Can any technology anywhere in the world claim to comply to this <br>
regulation ? For example 99.99% destruction efficiency means that 100 ppmw of <br>
say formaldehyde in your process off-gas has to be reduced below 0.01 ppmw, <br>
which I am sure is well below the detection limit of available detection <br>
devices. How you demonstrate 99.9999% removal is another matter again. <br>
<br>
2. How many pyrolysis plants are using the nuclear fission reactions that <br>
would be necessary to destroy the metals in their list ! <br>
<br>
3. What work around are people using to deal with emissions regulations <br>
that appear impossible to comply with ? <br>
