Equipment systems, principally installed at a terminal, designed to convert gasoline vapors into liquid. Generally, systems involve some combination of condensation, compression, refrigeration or incineration.
Gasoline vapors, collected at marketing facilities through use of Stage I vapor recovery equipment, are returned to terminals in tank trucks. There, as the tank truck is refilled, the vapors in the tank are directed through vapor processing systems. The liquid gasoline thus produced can then be added to the terminal’s gasoline stock.
