Description:
This document reviews the state of the art of air emissions from polychloroprene manufacture. The composition, quality, and rate of emissions, and their environmental effects are described. Polychloroprene is produced by the emulsion polymerization of 2-chloro-1,3-butadiene (chloroprene). Emissions include hydrocarbons, particulate, hydrogen chloride, and nitrogen oxides. To assess the severity of emissions from this industry, a representative plant was defined based on mean values for plant parameters. Source severity was defined as the ratio of the time-averaged maximum ground level concentration of an emission to the primary AAQS for criteria pollutants or to a reduced TLV for noncriteria pollutants. For a representative plant, source severities for particulate, hydrocarbons, nitrogen oxides, chloroprene, toluene, hydrogen chloride, and talc are 0.03, 23, 0.1, 4.3, 0.4, 0.9, and 3.4, respectively. Hydrocarbon emissions are controlled through a combination of process modifications. Particulates are controlled by exhaust systems in conjunction with wet scrubbers or fabric filters. Hydrogen chloride emissions are reduced by falling film absorbers and packed scrubbers.
