<div class="aolmail_MsoNormal">Some questions for the group. We have been asked to comply to the following regulation regarding operation of our thermal oxidiser. My questions are:</div>

<div class="aolmail_MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo1"><span style="mso-list:Ignore">1.<span style="font:7.0pt "> </span></span>Can any technology anywhere in the world claim to comply to this regulation ? For example 99.99% destruction efficiency means that 100 ppmw of say formaldehyde in your process off-gas has to be reduced below 0.01 ppmw, which I am sure is well below the detection limit of available detection devices. How you demonstrate 99.9999% removal is another matter again.</div>

<div class="aolmail_MsoNormal">52 Destruction efficiency</div>
<div class="aolmail_MsoNormal">(1) Group 6 treatment plant (other than flares) must be operated in such a way that the destruction efficiency of the plant, in relation to an air impurity entering the plant, is:</div>
<div class="aolmail_MsoNormal">(a) if the air impurity originates from material containing any principal toxic air pollutant-more than 99.9999%, or</div>
<div class="aolmail_MsoNormal">(b) in any other case-more than 99.99%.</div>
<div class="aolmail_MsoNormal">(2) An enclosed ground-level flare for the treatment of landfill gas must be operated in such a way that the destruction efficiency of the flare, in relation to landfill gas entering the flare, is more than 98%.</div>
<div class="aolmail_MsoNormal">(3) A reference in this clause to the destruction efficiency of Group 6 treatment plant in relation to an air impurity (including landfill gas) is a reference to the destruction efficiency of the plant, in relation to the air impurity, calculated by using the following equation:</div>
<div class="aolmail_MsoNormal">DE = (1 - MWout / MWin ) x 100</div>
<div class="aolmail_MsoNormal"> </div>
<div class="aolmail_MsoNormal">"DE" is the destruction efficiency, expressed as a percentage. </div>
