Measurement of Chlorobenzenes and Chlorophenols from a Small-Scale Fluidized Bed Type Incinerator for Municipal Solid Waste

Abstract

The sampling and analysis method is proposed for the measurement of chlorobenzenes and chlorophenols in emission gas of a municipal solid waste incinerator, based on results of recovery tests. The sampling method was evaluated by varying the sampling gas temperature and flow rate. According to the results of recovery tests, the lower temperature of sampling gas attained a higher absorption efficiency of diethylene glycol, and the low flow rate of sampling gas was beneficial to the activated carbon chip trap. In the analysis of sampled gas, the clean-up method was elaborated based on standard compounds. The amount of loss for each standard compound during clean-up procedure was less than 20%. Finally, two types of gas, one from the upper part of the fluidized bed and the other taken from the outlet of the secondary combustion chamber, were sampled and analyzed by the method proposed in this paper.

Methods for Measuring Total Organic Chloride Concentrations in Soil as Inorganic Chloride Concentrations Using UV Irradiation and Ion Chromatography

“…Chlorinated benzenes (M 1 CBz-H 6 CBz) and phenols (M 1 CP-P 5 CP) were used for the recovery test. Details of the analytical methods used for chlorinated benzenes and phenols are described elsewhere (1). According to the results of the recovery test, the monitored ion concentrations were below the detection limit.…”
