Abstract: Organic vapors emitted from a fryer containing a fatty substance heated to its vaporization temperature are condensed from a stream of exhaust air by a venturi-type scrubber. The scrubber condenses organic vapors into a liquid bath from which floatable by-products are removed and subjected to a further separation or clarification process. Air containing organic vapors is initially collected by a hood structure which defines a substantially confined emissions region above the fatty substance. In a preferred embodiment, the hood structure is configured to restrict the flow of ambient air into the emissions region, preferably causing air to enter the emissions region at a velocity of at least approximately 100 feet per minute.
