Pattern was confirmed by the increase of petrol remainder in the tank, the 
losses from the «big breath» when pumping increased. For tank of RGS-25 at 
increasing the residue was from 4 to 14 m

at losses from evaporation was studied 
with the aid of a double- reservoir system of AR-2 (Table 8). 
Fuel saving is higher, the smaller the ratio of the volume of received petrol to 
volume of intermediate reservoir GS: should be taken up petrol in small portions. 
Vapor emission into the atmosphere was reduced by 25-50%, depending on the 
occupancy of the intermediate tank with diesel fuel.

field of «Kokdumalak» under the «Mubarekneftegas» LLC since 25.04.2006, when 
a pilot plant was made on a scale of 1: 1000 to volume of industrial tank with 
filling the fuel surface sphere floats. Loss monitoring of gas condensate in 
industrial tank without pontoon and with pontoon depending on the temperature 
was carried out (Table. 9).
