摘要：In India nearly 40% of paper production is by big mills using sulfate process of cooking with emission of malodorous Non- Condensable gases such as methyl mercaptan, dimethyl sulphide, dimethyl disulphide and methanol. Most of the mills are in the vicinity of residential areas, so this odour source is a matter of great nuisance and no mentioned work has been done for the quantification, reduction and control of these gases. As per the literature these gases are highly toxic and affect the central nervous system. Though till date we don't have any limits on these malodorous gases, there will be growing resistance from public and NGO's in future for which industry will have to take appropriate steps. In this paper an attempt has been made for the quantification of these Non-Condasable gases from a mill based on hardwood and reduction in the malodorous gases due to the use of wet scrubber. The main aim of this study was to quantify amount of TRS gases so they can be completely reduced either by incineration or by other means.
