Compression condensation membrane separation process: physical separation, no secondary pollution
The compression condensation membrane separation process is a kind of VOCs with pure physical separation as the core.waste gas treatmentMethod. withactivated charcoalUnlike adsorption or high-temperature incineration, the process does not involve chemical reactions, does not consume adsorption materials, and does not produce hazardous waste.
Physical separation, no phase change contamination
Activated carbon adsorption transfers organic matter from the gas phase to the solid phase, and saturated carbon becomes hazardous waste;RTOCombustion burns organic matter into carbon dioxide and water, producing combustion by-products. Compressed condensation membrane separation relies on the difference in the permeation rate of gas molecules in the membrane material-VOCs molecules are preferentially permeated and air is trapped. The whole process is physical separation, the organic matter is not destroyed, nor is it transferred to the solid phase or liquid phase to become secondary pollutants.
Avoid hazardous waste at source
There are no consumables such as activated carbon in operation, no frequent replacement is required, and no hazardous waste such as saturated carbon is generated. The VOCs recovery technology achievements of Nanjing University of Technology and Nanjing University have clearly listed "no secondary pollution" as one of the core advantages of the process.
Closed cycle, near zero emissions
The condensed non-condensable gas is separated and enriched by membrane and then sent back to the front end for circulating treatment, and only clean air is allowed to be discharged from the system. Through this design of physical separation and circulation enrichment, a closed loop is formed inside the system, and organic matter is repeatedly captured in pipelines and components until liquefaction, and there is no new discharge point.
Pure physical separation, does not produce hazardous waste, does not produce combustion by-products, does not produce waste water waste residue. This is the essential difference between compressed condensing membrane separation and activated carbon and RTO at the level of environmental compliance.
