Electron Beam Degradation of Chlorinated Hydrocarbons Air-stripped from Polluted Ground Water: a Laboratory and Field Study
-
Lutz Prager
Abstract
Pilot-plant studies with strip-gas from a ground water remediation site at Dusseldorf, Germany (gas throughput 1000 m3 h-1, generated from 100 m3 h-1 water), demonstrated that vapour-phase electron-beam treatment of chlorinated hydrocarbons (CHC) such as cis-1,2-di-, tri- and tetrachloroethene, vinyl chloride, 1,1,1-trichloro- ethane, tri- and tetrachloromethane, which are released into the gas phase by soil-vapour extraction or by airstripping of contaminated ground water, is a very cost-efficient pollution-abatement technique. Laboratory studies have shown that for the chloroethenes, an OH-radical-induced chain reaction constitutes the main degradation pathway. Even at a relatively low dose of 2.5 kGy, electron-beam irradiation of CHC-polluted strip-gas (CHC total 3 ppmv, mainly cis-1,2-di-, tri- and tetrachloroethenes) achieves a higher than 90% decomposition of CHC with more than 80 % mineralization.
