VOC waste gas treatment equipment, condensation and membrane separation and solvent recovery

Traditional VOCswaste gas treatmentway, either.activated charcoalAdsorption orRTOCombustion, all focus on "standard emission. The standards have been met, but operating costs continue to be incurred, and the solvents in the exhaust gases are also destroyed.

The combined process of condensation and membrane separation accomplishes two things at the same time: the solvent in the exhaust gas is recovered, and the exhaust gas is discharged to the standard.

The condensation unit has completed the main recovery process. The exhaust gas is first pressurized by the compressor and enters the multi-stage condensing unit. Through graded cooling, most of the organic solvent in the exhaust gas is directly liquefied from gaseous to liquid solvent, which flows out of the collection tank with a purity of more than 90% and can be directly recycled for production.

The membrane separation unit is responsible for gatekeeping and recycling. The condensed tail gas still contains a small amount of unliquefied organic compounds and enters the membrane separation unit.gas separation membraneTaking advantage of the difference in permeation rate between organic molecules and air molecules in the membrane material, VOCs preferentially permeate through the membrane layer to form concentrated gas, which is sent back to the front end of the condensation for circulation treatment. Air is discharged up to standard.

Through this closed-loop design, the capture efficiency of the system for organic matter is significantly improved, the total recovery rate can reach more than 95%, and the emission concentration is stable to meet the requirements of environmental protection.

The equipment is driven by electricity, no natural gas consumption, no activated carbon consumables, and no hazardous waste. The process is pure physical separation, no combustion, no open flame, suitable for chemical, pharmaceutical and other explosion-proof places.

A device that simultaneously addresses both standard emissions and solvent recovery. Environmental compliance is the bottom line, and the recovery of solvents is the benefit. Before selection, do working condition detection and talk with data.
