Vertical above ground tanks with a double bottom, fitted with installations vapor recovery oil from the coolant mixture

摘要

The utility model is as follows. After receiving petroleum pipe enters the tank. In this case the fuel level starts to increase, and correspondingly decrease the volume of the vapor space. excessive vapor pressure generated in the tank. In order to capture vapor at a "large" breaths called breathing valve, check valve and the steam line which is connected to an additional tank, equipped with a receiver pair receives a coil type 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 are absorbed by low-octane petroleum product. Undissolved portion of gaseous hydrocarbons at the outlet from the reservoir is collected filter-absorber.; When "small" breaths associated with changing temperatures, with increasing steam pressure reservoir space, also called breathing valve and oil vapors through the steam line through the receiver with baffles fed into the tank with low octane component.; During the period of "small" couple breaths turn into a liquid by cooling in the heat exchanger.; In the case of fuel leakage through the tank bottom, petroleum remains in the reservoir due to the second bottom. Control gassed space between the bottoms is carried by a device equipped with a valve.
