Pulsed Corona Plasma Technology for Treating VOC Emissions from Pulp Mills

摘要

Under the DOE Office of Industrial Technologies Forest Products program various plasma technologies werernevaluated under project FWP 49885 "Experimental Assessment of Low-Temperature Plasma Technologies forrnTreating Volatile Organic Compound Emissions from Pulp Mills and Wood Products Plants". Thernheterogeneous pulsed corona discharge was chosen as the best non-equilibrium plasma technology for controlrnof the vent emissions from HVLC Brownstock Washers. The technology for removal of Volatile OrganicrnCompounds (VOCs) from gas emissions with conditions typical of the exhausts of the paper industry by meansrnof pulsed corona plasma techniques presented in this work. For the compounds of interest in this studyrn(methanol, acetone, dimethyl sulfide and α -pinene), high removal efficiencies were obtained with power levelsrncompetitive with the present technologies for the VOCs removal. Laboratory experiments were made usingrninstallation with the average power up to 20 W. Pilot plant prepared for on-site test has average plasma powerrnup to 6.4 kW. The model of the Pilot Plant operation is presented.
