ABSTRACT:
A system for controlling the emission of solvents from a printing press having a plurality of printing stations characterized by the solvents being evaporated from the ink solution in a drying hood or section of each of the printing presses and the volatile organic compound of the solvents being converted into harmless gases by heating in an oxidation chamber. The exhaust from the oxidation chamber is recirculated back to the drying hoods so that the amount of fresh air being brought into the system is minimized to reduce the amount of exhaust gases being discharged back to the atmosphere to minimize the amount of the volatile organic compounds being discharged to the atmosphere.
