A solvent recovery system is an industrial process technology designed to capture and reclaim volatile organic solvents from exhaust gas streams. Instead of destroying these valuable compounds through combustion, a recovery system physically separates the solvents from the air, purifies them, and allows them to be reused directly in the production process.

Excessive natural gas consumption of RTO waste gas treatment equipment is mainly caused by conservative manual temperature control, poor matching of waste gas concentration, redundant equipment energy consumption and poor system linkage.
