Wohong separation membrane, non adsorption and non combustion, pure physical separation

Traditional VOCswaste gas treatment, the idea is no more than two kinds:activated charcoaladsorption, orRTOBurning.

Adsorption transfers organic compounds from the gas phase to the solid phase; once the carbon becomes saturated, it is classified as hazardous waste, and its disposal costs are substantial. The combustion method is more direct. Organic matter is burned into carbon dioxide and water, which meets the standard. The solvent is also burned out, and the gas fee is still paid.

Wo Honggas separation membraneIt's the other way-pure physical separation.

How do you divide it?

Different gas molecules diffuse at different rates through polymeric membrane materials. Organic solvent molecules preferentially penetrate the membrane layer, and nitrogen and oxygen are blocked outside. Exhaust gas into the membrane module, one side of the high concentration of organic gas, the other side of the purified air.

This is the "dissolution-diffusion" mechanism: VOCs molecules first dissolve into the membrane material, and then diffuse through, the rate is much higher than the air molecules. The permeation rate of the polymer film for VOC is 10 to 100 times higher than that of air.

non-adsorption

No activated carbon, no spent carbon, no hazardous waste disposal, and no hassle with record-keeping or transfer manifests.

Does not burn

The whole room temperature to low temperature operation, no fire, no high temperature, from the source to avoid the risk of dioxin. In chemical, pharmaceutical, gas station these explosion-proof places, safety is the essential difference.

Good recovery after concentration

Membrane separation itself does not directly recover the solvent, its task is to concentrate-to increase the concentration of exhaust gas 5 to 10 times. The concentrated high-concentration gas is condensed again, and the solvent is liquefied into a liquid and flows out, which is directly returned to the production line. Membrane is responsible for fishing, condensation is responsible for collection, two sets are matched, the recovery rate is above 90%
