Primary oil and gas recovery

Primary oil and gas recovery is mainly to recover the oil and gas generated by the oil tank truck during oil unloading. A large amount of oil and gas will be generated during oil unloading. The primary oil and gas recovery device will install an additional recovery pipe in the underground oil storage tank of the gas station, and the oil and gas generated during oil unloading will be pumped back to the oil tank truck through this pipe for further centralized treatment.

Secondary oil and gas recovery

Secondary oil and gas recovery is mainly to recover the oil and gas generated by the fuel dispenser during refueling. The secondary oil and gas recovery device will install a sealing cover at the muzzle of the fuel dispenser. During refueling, the sealing cover will block the inlet of the fuel tank of the vehicle, and the true air recovery pump inside the fuel dispenser will suck the oil and gas in the fuel tank of the vehicle, Then it returns to the oil storage tank through the recovery pipe built in the refueling gun for further treatment.

Tertiary oil and gas recovery

The third oil and gas recovery is to change the secondary recovered oil and gas into liquid gasoline through technical means, and reuse it to improve the profit of the gas station.

At present, the liquefaction technologies of the three oil and gas recovery equipment mainly include: condensation, membrane adsorption and membrane separation. Condensation is the mainstream at present. Membrane separation is the most advanced, with high efficiency and low maintenance cost.
