NOVEL PLASMA CHEMICAL TECHNOLOGIES - PPCP AND SPCP FOR CONTROL OF GASEOUS-POLLUTANTS AND AIR TOXICS

The pulse corona induced plasma chemical process (PPCP) and the surfac e discharge induced plasma chemical process (SPCP) represent novel tec hnologies for generating copious active radicals under ordinary temper ature and pressure for control of gaseous pollutants (NO(x), SO(x), VO Cs) and air toxics (Hg and other readily vaporized metals, trichloroet hane, trichloroethylene, freons, toluene, dioxines, etc.) as well as o dors. PPCP and SPCP are completely dry processes having a simple const ruction, and their overall cost (both initial and running) is one of t he lowest among the processes for control of gaseous pollutants. They can be combined with a wet ESP, a bag-filter with absorbent powder coa t, a catalyst bed, or an active charcoal bed for the final removal of the reaction products.
