General oil and gas recovery is divided into five related steps:
The first stage is the recovery. In this stage, when the tanker is unloading oil to the underground storage tank, the oil and gas with the same volume as the discharged oil are replaced, so oil and gas recovery is needed. The second stage of recovery is that when the tanker sends oil, the oil and gas generated in the oil tank device of the automobile can be collected into the underground oil storage tank through the oil and gas recovery hose by using the oil and gas recovery double pump as the power.
The next step is to carry out a post-treatment of oil and gas recovery. At this time, the oil and gas pressure in the underground oil storage tank of the oil station should be controlled, and the oil and gas can be converted into gasoline with very high concentration of oil and gas and liquid for recycling by using compression condensation and membrane separation technology. In this process, clean air can be released at the same time, and the loss of oil and gas breathing can be ensured to be almost zero.
Finally, we should pay attention to improving the safety level of oil and gas recovery, controlling the volatilization of gasoline well, reducing the potential safety hazards of gas stations, and protecting the ecological environment. Oil and gas recovery can reduce the release of some harmful gases burning gasoline to pollute the air and ensure human health and environmental protection. We know that the efficiency of oil and gas recovery is very high, above 95%, so it can still reduce the loss of gasoline to a great extent.
