Challenges with Chlorinated Hydrocarbon VOCs
Chlorinated hydrocarbons such as dichloromethane, dichloroethane, and chloroform are commonly used as solvents or raw materials in industries like pharmaceuticals, pesticides, and fine chemicals. Due to their low boiling points, these substances are prone to volatilization during production, resulting in:
- Economic Loss: Material loss from volatilization.
- Environmental Pressure: Challenges in meeting exhaust treatment and emission standards.
Traditional treatment methods, such as activated carbon (or carbon fiber) adsorption, are not ideal due to their:
- Low Selectivity: Ineffective adsorption of chlorinated hydrocarbons.
- Variable Performance: Inconsistent removal and recovery rates.
- High Maintenance: Frequent replacement generating hazardous waste, increasing operational burdens.
Additionally, regenerative thermal oxidizers (RTOs), widely used for VOCs treatment, are limited in handling chlorinated hydrocarbons. Combustion of these compounds often produces corrosive hydrogen chloride gas and carcinogenic dioxins, restricting the application of RTOs to waste gases with chlorinated hydrocarbon concentrations below 200 mg/m³.
