Abstract
A system for reducing hydrocarbon emissions from a high speed liquid reprography process. Hydrocarbon ladened vapors from the reprography process are directed through an activated charcoal bed. The bed is regenerated from time to time by a flow of controlled temperature regenerating air. Whereas the reprography process generates hydrocarbons at a highly fluctuating rate and mixed in large volumes of air, the carbon bed regeneration produces hydrocarbons at a controlled rate in a small volume of air. These hydrocarbons are removed by removal means which may be either a catalytic reactor or a condensation device.
