Reduction of chlorinated and halogenated solvents using thermal oxidizers

The purpose of this article is to reduce chlorinated and halogenated solvents from dichloroethane and methyl chloride production processes in petrochemicals. For this purpose, a thermal oxidizer was used along with a scrubber. The Thermal Oxidizer operates with a maximum air flow of ۳۶۰۰۰ Nm۳/h, Installed electrical power of ۱۰۰ kW and a gas burner capacity of ۱۰۰۰ kW. Its dimensions are ۵ * ۵ * ۱۲ m۳ and its chimney height is ۱۰ meters. The results indicated that all monitored pollutants were maintained well below their respective regulatory limits. Hydrochloric acid, vinyl chloride and ۱,۲- dichloroethane, chlorine, volatile organic compounds, methane, carbon monoxide, sulfur oxides, total dust, dioxins (PCDD), and ethyl chloride were either not detected or measured at trace levels significantly lower than permitted values. Nitrogen oxides were the only component detected at a comparatively higher concentration, yet still remained below the allowable limit (۶۶ mg/Nm³ measured vs. ۱۰۰ mg/Nm³ permitted). Overall, the test-run confirmed effective emissions control and compliance with environmental standards across all evaluated parameters.
