Condensed membrane recovery process to recover the solvent from the organic tail gas.

Organic waste gas treatment should not rely on “burning” or “adsorption” to eliminate solvents. If it can be turned into a liquid and directly recycled to the production line, it is the most effective way to use resources.

The condensed film recovery process does a simple thing: take back the solvent in the organic tail gas one by one.

The first step: condensation, the solvent into a liquid

The exhaust gas enters the condensing system after compression. The temperature is gradually reduced, and the organic compounds with different boiling points are liquefied in turn. Out of the liquid, directly is the solvent, the composition is clean, can be used back to the production line. No need to buy new ones, the cost will naturally come down.

The second step: membrane separation, the residual fishing again

In the condensed tail gas, there is still a small amount of organic matter that is not liquefied. This part enters the membrane separation device.gas separation membranePermeability is selective-organic gases are easier to pass through. The passing gas is sent back to the front end to condense again; the air is intercepted, purified and discharged. In this way, the condensation is confiscated and the film is sent back to the system for recycling.

The system is closed, and the recovery rate is stable above 95%

The two-stage process is closely connected to form a closed loop. Organic matter circulates in the system until it is liquefied and recovered; the concentration of the discharged gas is stable and meets the environmental protection requirements. No adsorption material is required, no hazardous waste is generated, and no gas combustion is required. The equipment is operated by electric power, and the operation and management are simple.

What kind of working condition is suitable?

Suitable for medium and high concentration of organic tail gas, the solvent has recovery value, and the component is relatively clear. The industry covers chemical, pharmaceutical, printing, storage and transportation, etc. Before selection, it is recommended to test the working conditions first, and then match the equipment specifications after determining the components and concentrations.
