Can VOC tail gas treatment manufacturers handle dichloromethane? It is important to choose the right process.

Dichloromethane is a common solvent in the chemical and pharmaceutical industries, but itswaste gas treatmentIt's really difficult. It has a low boiling point and evaporates rapidly at room temperature; being chlorine-containing, it readily forms byproducts via combustion and poses a corrosion risk to equipment.activated charcoalAdsorption can adsorb part of it, but dichloromethane volatilizes quickly, carbon layer saturation is also fast, carbon exchange is frequent, saturated carbon as a hazardous waste disposal cost is not low.

According to the characteristics of dichloromethane, compression condensation membrane separation is a more suitable process route. The membrane module first concentrates the dichloromethane in the waste gas, and then enters the condensation unit to be recovered as a liquid state. Because the membrane separation reduces the processing load of the condensation unit, the condensation temperature does not need to be too low, and the operation energy consumption is relatively controllable. The whole process is mainly physical separation, does not involve combustion, and avoids the by-product problem of halogen-containing waste gas incineration.

Looking for a VOC tail gas treatment manufacturer to treat dichloromethane can focus on whether the other party has experience in treating halogen-containing waste gas by membrane method and the operating parameters of the recovery system. Whether the process selection is reasonable depends on the matching degree of exhaust gas concentration, air volume, components and process configuration.

LuoyangWohong PetrochemicalEquipment Co., Ltd. has practical project experience in the field of compression condensation membrane separation, and can match the process plan according to the specific parameters of dichloromethane waste gas. Enterprises in need can complete the exhaust gas detection first and then communicate the technical details.
