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

The solvent in organic tail gas, to put it bluntly, is a raw material bought with money, and it is wasted when discharged. Condensed membrane recovery process is to separate the solvent that was originally to be discharged from the exhaust gas and turn it into a reusable liquid.

Condensation first, put most of it away

After the exhaust gas enters the system, it first passes through the condensation unit. Through the step-by-step cooling, the temperature is gradually reduced from normal temperature, and the organic matter with different boiling points is liquefied in turn. The condensed solvent flows out of the collection tank with high purity and can be directly returned to the production line. This step solves the subject recycling problem.

Separate the membrane again and remove the residue.

There is a small amount of organic matter in the condensed tail gas that is not liquefied, and this part enters the membrane separation unit. Membrane materials have different permeation rates for different molecules-organic matter preferentially permeates to form concentrated gas, which is sent back to the front end of condensation for reprocessing. Air is trapped and discharged up to standard. This step sends back the part of the condensate that has been confiscated, forming a closed loop.

Condensation is responsible for turning most of it into liquid, and the membrane is responsible for getting the residue back. With the combination of the two, the recovery rate can reach more than 95% and the emission concentration can reach the standard stably.

Equipment operation is not complicated

powered by electricity, no need for natural gas, noactivated charcoalConsumables do not generate hazardous waste. The whole room temperature to low temperature operation, no burning, no open flame. It is suitable for organic exhaust gases with medium to high concentrations that have recycling value, covering common solvents such as hydrocarbons, halogenated hydrocarbons, alcohols, esters, and ketones.

The process runs with pure physical separation, does not rely on consumables, and the emission is stable. Before selecting equipment, it is recommended to first conduct a process condition assessment and match the equipment specifications based on concentration, composition, and airflow rate.
