Abstract
An apparatus for recovery of condensible vapors as components in waste gases which are to be flared, comprising a flare system, including a flare gas line leading to a flare stack. Inserted in the flare gas line is a gas-to-liquid heat exchanger, to cool the flare gases prior to passage to the stack. The cooling is to be selected temperature, where condensible vapors in the waste gases, the dew points of which are above the selected temperature, will condense. Means are provided for separating the condensed vapors from the remaining flare gases. Thermostatic means are provided for stopping the circulation of said cooling liquid whenever the ambient temperature drops below the selected temperature.
