VOCWaste gas treatment equipmentSuitable for ketone ester hydrocarbon halogenated hydrocarbon
The composition of VOCs waste gas is complex, and the types of solvents emitted by different industries are quite different. The Wo Hong compression condensation membrane separation equipment has a good recovery effect on common organic solvents such as ketones, esters, hydrocarbons, halogenated hydrocarbons, etc.
Applicable main solvent type
The range of organic matter that can be recovered by the equipment covers several common categories:
Ketones: acetone, butanone, cyclohexanone, etc
Esters: ethyl acetate, butyl acetate, etc. (common in printing and coating industries)
Hydrocarbons: n-hexane, cyclohexane, toluene, xylene, etc.
Halogenated hydrocarbons: dichloromethane, chloroform, chlorobenzene, etc. (common in pharmaceutical and chemical industries)
Alcohols: methanol, ethanol, isopropanol, etc
Ethers: tetrahydrofuran, ether, etc
Process principle: combination of condensation and membrane separation
The process adopts the combined route of "compression condensation + membrane separation. The exhaust gas first enters the condensing unit through compression and pressurization, and most of the organic solvents are liquefied from gaseous to liquid through graded cooling, which can be directly used. After condensation, the tail gas enters the membrane separation unit, and by using the difference in permeation rate between organic molecules and air molecules in the membrane material, the organic matter preferentially permeates to form concentrated gas, which is sent back to the front end for circulation treatment, and the air meets the discharge standard. The entire system operates in a closed loop, with a recovery rate exceeding 95%.
Applicable operating conditions
The equipment is suitable for VOCs waste gas with medium and high concentration (above 1000 mg/m) and recovery value. Before selecting equipment, it is recommended to first conduct exhaust gas testing to determine the composition and concentration of the gases. Luoyang Wo Hong can match membrane module specifications according to specific solvent types and provide full-process services from working condition detection to equipment configuration.
