Abstract
An apparatus for recovering vapors expelled from a tank during filling. The apparatus includes a conduit arrangement for selectively conducting vapor to one of a storage tank or a vapor liquefying means. Vapor conducted to the liquefying means is contacted with refrigerated liquid for liquefaction by condensation and/or absorption. Periodically, liquid and liquefied condensable portions of the vapor are discharged from the liquefying means and are replaced with fresh liquid. A pressure controller determines the flow path of the vapor to the storage tank or the vapor liquefying means wherein only a portion of the vapor is conducted to the vapor liquefying means.
