Vapor Recovery for Gas Station

1. What is Vapor Recovery?

Refers to the collection of volatilized oil vapor through vapor recovery technology during the storage, transportation,

loading and unloading, and retailing of oil products, and the conversion of oil vapor from the gaseous state to a liquid state through absorption, adsorption, or condensation, and then into gasoline again.

2. Classification

① Primary Vapor Recovery

<yoastmark class=

refers to the process in which the tanker unloads oil, the oil vapor in the oil tank of the gas station is recycled into the tanker, and the tanker recycles the oil vapor into the oil depot.

This process means that when the gas station unloads oil, in addition to connecting the oil unloading pipeline,

it also needs to connect an oil vapor recovery pipeline. The purpose is to collect the oil vapor in the oil tank into the tanker when unloading oil. In a nutshell, it is unloading oil vapor recovery.

② Secondary Vapor Recovery

Secondary Vapor Recovery

It refers to the use of special devices on the vapor recovery nozzle to recover the oil vapor that originally escaped from the car tank in the air into the oil tank through the recovery nozzle and vacuum pump.

Corresponding to the scene, that is, during the refueling process, the oil vapor is recovered through the vapor collecting hood,

and recovered into the oil tank through the vacuum pump. In a nutshell, it is refueling vapor recovery.

③ Tertiary Vapor Recovery

Tertiary Vapor Recovery

It refers to the treatment of the exhaled oil vapor in the oil storage tank during the storage of oil products.

The tertiary vapor recovery system needs to be installed in the gas station that has completed the transformation of the secondary vapor recovery system.

As the amount of oil increases, the oil storage tank pressure will continue to rise. When the pressure of the oil storage tank rises to a certain value,

the tertiary vapor recovery equipment starts to extract oil vapor from the oil storage tank at a certain flow rate,

transforms it into a liquid state, and returns to the oil storage tank while reducing the pressure in the oil storage tank.

3. The Importance and Benefits of Vapor Recovery

Environmental protection: Helps prevent waste oil from being disposed of improperly,

thereby avoiding pollution of soil, water sources, and ecosystems, and reducing adverse impacts on the environment.

Resource reuse: Waste oil can be converted into useful renewable resources, improve energy utilization, reduce the demand for raw resources, and reduce carbon emissions.

Cost savings: Companies can reduce waste disposal costs. At the same time, the utilization of renewable resources can also create added value for enterprises.

Sustainable development: Choosing vapor recovery is the embodiment of corporate social responsibility and environmental awareness. It helps to enhance the corporate image and win the support of consumers and partners.

In conclusion, vapor recovery is an important practice that benefits the environment and sustainable development, making an important contribution to creating a cleaner and healthier future.
