<p num="1"><br/><br/><br/><br/>Steam stripper off gas from chemical pulp mills, for example kraft or sulphite <br/><br/>pulp mills is rich in methanol and totally reduced sulphur (TRS) compounds. <br/>This gaseous stream is usually burned to avoid further handling of this TRS-<br/>rich, odorous stream. We found that once this gaseous stream is condensed, it <br/>can be used as a reducing agent in the chlorine dioxide generator, in place of <br/><br/>purchased methanol. Surprisingly, we found that, in addition to the methanol <br/>component, the TRS components act as reducing agents during the production <br/>of chlorine dioxide or, at the very least, do not consume chlorine dioxide. <br/>The <br/>use of this stream in the ClO2 generator will allow pulp mills to reduce or <br/>eliminate the consumption of purchased methanol while providing a new <br/>approach to deal with TRS compounds in the chlorine dioxide generator rather <br/>than employing a dedicated TRS incinerator or any other combustion device.<br/>
