INSTALLATION vapor recovery of petroleum products from road tankers and storage tanks OF COOLING MIXTURE

摘要

The utility model is as follows. Before filling a tanker oil product offers cover car tank cap. On the neck of the tank device is set on a flexible removable sleeve. Through the receiving line automotive tank petroleum enters the tank truck. In this case the fuel level starts to increase, and correspondingly decrease the volume of the vapor space. The tank is pressurized vapors. In this case, a pair of flexible sleeve portion received in the steam line and pumped by the compressor through the open pressure compressor check valve in the main steam pipe connected to an additional tank, equipped with a receiving device. Vapors pass heat exchanger with the pumped fluid that is supplied from the vessel via conduit a cooling system with a pump. Cooling the mixture in the heat exchanger creates a temperature at 7-9 degrees Celsius below the earth's surface temperature. The main part of the gaseous hydrocarbons as a result of cooling in the heat exchanger passes into the liquid state, and the pairs are not passed into the liquid, stratified two partitions with holes of different diameters and absorbed low-octane petroleum product. Undissolved portion of gaseous hydrocarbons at the outlet from the reservoir is collected filter-absorber. After pouring closure oil tank in an automobile compressor and cooling system pump shut off. Ingress of vapor in the tank with a check valve prevents the oil product. By "large" and "small" breaths with increasing pressure tank vapor space, which is equipped with the working and pressure-vented with metering and light hatches ventilation pipe, the hatch-manhole, the pipeline for the reception and delivery of petroleum products with valves, called breathing valve operating pressure, and a pair of oil fed through the steam line to the heat exchanger with the pumped fluid that is supplied from the vessel via conduit a cooling system with a pump. After the heat exchanger the vapor mixture with the liquid petroleum product is supplied to the receiving device with baffles and a reservoir of low-octane component. Incoming oil vapors in the vapor line from the tank portion to trap fuel vapors from the automobile tank prevents return valve.
