Abstract: A method of recovering vapors from exhausts or vents of containers of volatile substances comprising the steps of: providing a scrubber for connection to the vapor space of the container to receive a flow of vapors therefrom; providing a reservoir of absorber fluid; cooling the absorber fluid; introducing the cooled absorber fluid into the scrubber for intimate contact with the flow of vapors therethrough; and returning the vapors absorbed by the cooled absorber fluid to the container. The scrubber may include a spray nozzle adapted to spray cooled absorber fluid in a direction generally concurrent with the flow of vapors. Alternate methods of returning absorbed vapors to the container are disclosed.
