A process for the containment and recycle of organic vapors from an open container or tank that utilizes a chilled gas blanket over the surface of the organic liquid, with a continuous recirculaton of the chilled gas through a condenser heat exchanger for cooling the gas flow and condensing and returning the condensed vapor to the tank or container. Included are the means of distribution of the recirculated chilled gas, the means of collecting the recirculated chilled gas, the means of providing an enclosed chilled gas recirculation system, the apparatus for condensing the vapor to liquid, the apparatus for collecting and recycling the condensed vapor, the apparatus for providing a full open access to the top of the tank or container and the apparatus for control of the flow of the recirculated chilled gas. |
