The concentrated oil and gas released by the vacuum pump enters into the absorption tower and contacts with the gasoline from the tank area against the current. Based on the principle of similar phase dissolution, the concentrated oil and gas is absorbed by the gasoline and then returns to the tank area through the pipeline pump.

Loading loss includes oil and gas loss at automobile gas stations and oil and gas loss during loading and unloading of trains, cars, ships and other means of transport.This part of the loss is much greater than the breathing loss of the tank.According to foreign studies for many years, in the loading process, the hydrocarbons discharged into the atmosphere is 1.3kg/m3, and the oil and gas wasted in a loading and unloading operation accounts for about 0.17% of the whole loading amount.
