VERFAHREN UND VORRICHTUNG ZUR RUECKGEWINNUNG VON KOHLENWASSERSTOFFEN AUS EINEM GAS-LUFT-GEMISCH

摘要

A process and a device for recovering hydrocarbons from a gas-air mixture operates in the following manner: first the gas-air mixture is cooled and caused to condense. The hydrocarbons still remaining in the gas-air mixture after condensation are burned in an internal combustion engine. The power thus generated by the engine is used to operate the cooling installation used for the cooling and condensation processes. The cooling installation is so designed and run that the gas-air mixture is cleansed as far as possible of hydrocarbons and impurities on passing through the installation. Fuel is metered into the gas-air mixture downstream of the cooling installation and upstream of the internal combustion engine.
