A method and apparatus for recovering a contaminant solvent from a gas such as air or the like. Contaminated air or gas to be treated is initially directed through a first absorber containing an oil which absorbs the solvent to cleanse the gas. The air or gas may then be returned to the environment. The oil is transferred to a stripper, where inert gas passing therethrough absorbs the solvent to cleanse the oil. Condenser means adapted to receive inert gas outputted from the stripper facilitates recovery of the solvent. The inert gas is further cleansed in an auxiliary oil absorber and from thence passes to an activated charcoal filter which removes remaining traces of solvent from the inert gas through the process of adsorption. Cleansed inert gas is then recycled by returning it to the stripper for repetition of the process. Absorbent oil is also recycled by continuously pumping it between the stripper and the absorbers.

Method and apparatus for solvent recovery

In carrying out the method of sampling gas with our novel apparatus, a user will blow air into an elastic fluid impervious diaphragm which extends into the mouth of a rigid container. As the elastic diaphragm expands inwardly it forces air or gas outwardly of the container through a valve-controlled port, the diaphragm will eventually engage and adhere to substantially the entire inner surface of the container and the valve-controlled port will then be closed. The container will then be placed in a sampling zone and the valve-controlled port will again be opened to communicate with the sampling zone to thereby permit gas to enter and fill the container. The valve-controlled port will then be closed.
