VOCs recovery system by compression condensation film method

The compressed condensed membrane VOCs recovery system is a physical separation as the core.waste gas treatmentDevice. The system will be compression, condensation and membrane separation three technical gradient coupling, through the coordinated operation of each unit, to achieve efficient recovery of organic solvents and exhaust emissions standards.

After the exhaust gas enters the system, it is first pressurized by the compressor to increase the partial pressure of organic matter in the gas and create conditions for subsequent condensation. The pressurized gas enters the multi-stage condensation unit, and most of the organic matter in the exhaust gas is changed from gaseous to liquid by gradual cooling, and the liquefied solvent is separated by the collection tank and can be directly recycled for production. The condensed tail gas still contains a small amount of organic matter that has not been liquefied, and this part of the gas enters the membrane separation unit.gas separation membraneBy leveraging the difference in permeation rates between organic molecules and air molecules through the membrane material, organic compounds preferentially pass through the membrane to form a concentrated gas stream, which is then returned to the compressor inlet, mixed with fresh waste gas, and reintroduced into the condensation process; the retained air is discharged after meeting emission standards. The whole system forms a closed loop.

The system is driven by electricity, does not consume natural gas, and is not in operation.activated charcoalWait for consumables to be replaced; no hazardous waste is generated. The process is normal temperature to low temperature operation, does not involve combustion, no open flame, and has good applicability in explosion-proof places. The equipment adopts skid-mounted design, each unit is integrated on the steel base, and the assembly and debugging are completed before leaving the factory. The site can be put into operation only by connecting the power supply and gas circuit. The installation period is short and the floor area is small. Equipped with PLC automatic control system, no special person on duty.

The system is suitable for VOCs waste gas with medium and high concentration and solvent recovery value. Common recyclable solvents include ketones, esters, hydrocarbons, halogenated hydrocarbons, alcohols, ethers, etc. Before selection, the exhaust gas working condition detection shall be completed to obtain basic parameters such as concentration, component and air volume. LuoyangWohong PetrochemicalEquipment Co., Ltd. can provide system design and manufacturing services according to customer working condition parameters.
