ABSTRACT:
This patent specification discloses a system for reducing pollution of soil, water and air due to spillage of liquid hydrocarbons. Such liquids are transferred by gravity flow from a tank truck compartment to a bulk storage tank through a flexible loading hole. The hose is connected to the bulk storage tank pumping system by a ground level connector which is enclosed within an open top box. The bottom plate of a box is tilted to horizontal and forms a cover for an unloading chamber or pot serving as a pump reservoir between the hose connector and the storage tank pump system. The sidewalls of the box extend above and around the hose connector to catch spills or leaks from the gravity fed loading hose when it is connected to, or disconnected from, the pumping system. A sump pot is arranged at the low end of the tilted bottom plate for recovery of any spilled liquid. The box may accommodate from one to several unloading headers with a single sump pot. Liquid in the sump pot is drained to a slop tank for recovery or disposal. A vapor recovery system is connected to the sump pot drain line and through a gas vent valve to the vapor space at the top of each unloading chamber to prevent air pollution also.
