Introduction of Compression Condensation Membrane Separation Process

The compression condensation membrane separation process is a combined technology for the recovery and treatment of medium and high concentration organic waste gas, which combines compression condensationgas separation membraneThe two physical separation methods are organically combined to realize the efficient recovery and resource utilization of VOCs.

The process is divided into three steps. The first step is compression pretreatment. The exhaust gas is first pressurized by the compressor to increase the partial pressure of organic matter and create favorable conditions for subsequent condensation. The second step, cascade condensation. The compressed exhaust gas enters the three-stage condensation unit, and the temperature gradually drops from normal temperature to minus 15 to minus 25 degrees Celsius. Most of the organic matter is liquefied into solvent and flows out from the bottom for recovery. The third step is membrane separation. A small amount of uncondensed tail gas enters the gas separation membrane module, and the membrane material has selective permeability to organic molecules. After being enriched, the organic matter is recycled back to the condensation inlet for further treatment, and the clean air is directly discharged.

The core of this process is that compression improves the condensation efficiency, membrane separation captures the residual organic matter not caught by condensation, and the three-stage coupling enables the overall recovery rate to reach more than 95%. withRTOCompared with other combustion processes, it only uses electricity without burning gas, significantly reduces energy consumption, and there is no secondary pollution such as nitrogen oxides and dioxins. withactivated charcoalCompared with adsorption, there is no frequent replacement of consumables and the trouble of hazardous waste disposal.

The compression condensation membrane separation process is suitable for medium and high concentration in chemical, pharmaceutical, printing, coating, electronics, gas station and other industries.waste gas treatmentScenarios, especially suitable for solvents with recycling value, enterprises want to waste to raise waste conditions. The equipment adopts the skid-mounted integrated design, the assembly test is completed before leaving the factory, the on-site installation cycle is short, the floor area is small, the PLC automatic control is equipped, and the operation is simple.
