High concentration VOCs waste gas recovery equipment compression condensation membrane separation process, the higher the concentration, the more cost-effective

For high-concentration VOCs waste gas, destruction is the cost and recovery is the benefit.

The compression condensation membrane separation process is not a combustion route, but a physical separation. The waste gas is compressed first, then condensed, and most of the organic matter is directly converted into liquid for recovery. The uncondensed tail gas passes through the membrane module, is further enriched and then sent back to the front end for circulation treatment. The entire process uses only electricity; no gas is burned, and there is no...activated charcoalConsumables do not generate hazardous waste.

Why is the higher the concentration, the more cost-effective?

The efficiency of the condensation recovery depends on the partial pressure of the organics in the off-gas. The higher the concentration, the greater the amount of solvent contained in the unit exhaust gas, and the greater the absolute amount of condensation recovery. With the same equipment and the same power consumption, treating 5000 mg per cubic meter of waste gas can recover more than twice as much solvent than treating 2000 mg per cubic meter of waste gas. The recovery of high concentration waste gas is higher and the payback period is shorter.

The technology is suitable for a wide range of concentrations, not only for medium and high concentrations of VOCs, but also for low concentration exhaust gas. Through membrane separation pre-concentration, the load and energy consumption of the condensation unit can be reduced. The recovery rate of common solvents (ketones, esters, hydrocarbons, halogenated hydrocarbons, etc.) can reach more than 90%.

The equipment adopts skid-mounted design, 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, no special duty.

Before selection, it is recommended to test the working conditions first, get the concentration, composition and air volume data, and then judge the recovery value. Luoyang Wohong offers free operating condition testing to help you calculate the costs accurately. The higher the concentration, the more the recovery.
