INSTALLATION vapor recovery TRANSPORT OIL railway tanks

摘要

Estimated useful model relates to devices for trapping vapors and draining oil from railway tanks and can be used in the petrochemical and other petroleum products industries. The solution of this object is achieved in that the housing safety suction tank valve installed total pipe line for discharging vapors with a check valve connected with double-walled tank, partially filled with low-octane component that is equipped with a receiving device for the fuel vapor and the safety valve with filter absorber, with this tank is mounted on a trolley with wheels, it is filled with air space between the walls and partitions mounted inside the tank of rigidity minute holes to move low octane components throughout the volume of the tank during movement of the tank with a view to absorption of oil vapor. The utility model is as follows. When "small" breaths associated with changes in temperature and an increase in the vapor space pressure slam-open valve inlet and a pair of oil based on the total piping line through the receiver with grids having holes of different diameters are supplied to a double-walled tank with low octane component. Thus most of the vapor into a liquid by cooling a double-walled tank. Another part of the oil vapor by the displacement openings nizkooktanovogo component partitions stiffness over the entire volume of the tank during movement of the railway cistern absorbed nizkooktanovoj component. Undissolved part oil vapors at the outlet of the tank at the opening of the safety valve is collected filter-absorber. Upon arrival at the point of the tank rail reception level of the mixture of low octane components with the petroleum product is checked through the measuring tank hatch and if necessary, the mixture is drained through the drain pipe. Utility model allows catching pair oil from railway tanks, but also significantly reduces emissions of fuel vapors into the atmosphere. When the mixture of oil vapor from the low-octane component blends of double-walled container in a separate container and is dealt a refinery to produce commodity petroleum products.
