Recently, Shandong Keshiman Environmental Technology Co., Ltd. launched an oil and gas recovery system for gas stations. This equipment, designed for fuel refueling scenarios, collects and treats oil and gas volatilized during operations, meeting the daily environmental protection and maintenance needs of gas stations.
I. Product Introduction
This oil and gas recovery equipment is a supporting device for volatile organic compound (VOC) treatment at gas stations, integrating an oil and gas collection unit, an adsorption treatment unit, and an automatic control system. The equipment can collect oil and gas volatilized during unloading, vehicle refueling, and storage tank stagnation in a closed system. The internal treatment unit separates the oil and gas components, and the treated gas is discharged externally. The collected fuel can be returned to the storage tank. The entire system can be installed with existing gas station pipelines and fuel dispenser systems and can be equipped with an online monitoring module to record relevant operational data.
II. Main Product Features
High degree of automation; it can automatically start and stop based on changes in internal tank pressure, requiring no continuous manual intervention.
Equipped with corresponding monitoring and alarm modules, the system can issue alert signals when abnormal equipment operation occurs, facilitating timely troubleshooting by maintenance personnel.
The structure is relatively compact, occupying minimal space and facilitating installation and subsequent maintenance.
It adopts a dual-adsorption tank alternating operation mode, with adsorption and desorption regeneration occurring synchronously, ensuring continuous operation of the device.
The electrical components of the equipment are explosion-proof, suitable for the flammable and explosive working environment of gas stations.
III. Equipment Usage
After completing the installation and connection with the gas station's oil tanks and oil and gas pipelines, professional personnel will perform commissioning, set pressure trigger parameters, and check the pipeline's airtightness.
The equipment is then connected to the station's power supply system, initiating the automatic control program and entering standby monitoring mode. When the pressure inside the storage tank reaches the set threshold, the device automatically starts, collecting volatile oil and gas from the tank.
The oil and gas enter the adsorption unit for enrichment. After saturation, the system automatically switches to the adsorption tank, performing vacuum desorption on the saturated tank. The desorbed oil and gas condenses and liquefies, flowing back to the storage tank.
During daily use, staff should regularly check the equipment's operating prompts and inspect the pipeline's sealing and the condition of the adsorption material according to the maintenance cycle. If an alarm is triggered, the machine should be shut down for maintenance.
IV. Scope of Application
This oil and gas recovery equipment is primarily suitable for gasoline refueling stations and can be used in conjunction with conventional underground oil storage tank sites, covering scenarios involving the collection and treatment of oil and gas generated during unloading operations, vehicle refueling, and tank breathing. The equipment can be used in conjunction with newly built gas stations or for upgrading existing gas station environmental protection facilities. Application scenarios must meet the requirements for basic site conditions, power supply, and pipeline layout.
Summary
This oil and gas recovery equipment relies on adsorption recovery technology and automated control to achieve closed-loop collection and treatment of oil and gas. It has a compact structure, a clear operating procedure, and is suitable for most gasoline refueling station scenarios. Proper installation and regular maintenance are essential for the equipment's operation. Provided that installation conditions and operation and maintenance management requirements are met, it can be used as a supporting facility for oil and gas treatment at gas stations.
