Abstract
A vapor recovery system for a fuel filling installation in which the recovered air-vapor mixture is pumped to the submerged end of a discharge pipe. The discharge pipe is connected to a closed tube which extends along the bottom of an underground fuel tank. The closed tube has a porosity that generates very small bubbles from the air-vapor mixture that flows through the fuel within the tank. A vent pipe for the underground tank separates air from the air-vapor mixture through decreasing density separation by means of a large cross-section for the vent pipe and by providing baffles in the pipe interior.
