Gasoline vapor recovery system and method
A gasoline vapor recovery system is described which is particularly adapted for bulk flow plants. The system includes an absorber into which raw gasoline vapor is introduced, as by a connection from a tank truck while the tank truck is loaded with gasoline. Light oil, such as kerosine, is pumped into the absorber and acts as a carrier, carrying the gasoline vapor through a heat exchanger and trim heater to adjust the temperature and then through a stripper, from which the gasoline is stripped from the kerosine as a vapor. The gasoline vapor is drawn from the stripper to a gas cooler by a vacuum pump and then compressed and condensed in the form of a liquid blendable into a desired grade of gasoline. The lean oil from the system may be pumped back to the absorber and reused.
