Guidelines for Selection and Operational Benefit Analysis of Three stage Oil and Gas Recovery Equipment and VOCs Exhaust Gas Treatment Device at Gas Stations

With the continuous tightening of environmental regulations, gas station oil and gas recovery has become a standard in the industry. Especially the three stage oil and gas recovery equipment and the supporting VOCs tail gas treatment device are not only key links to meet policy requirements, but also important means to achieve resource recovery and reduce operating costs. This article will provide a clear and practical reference for gas station owners and maintenance personnel from technical principles, core component selection to actual operational benefits, helping you make scientific decisions and enhance your comprehensive competitiveness.

The tertiary oil and gas recovery system is the end guarantee of the oil and gas recovery system. Its core task is to pump back the oil and gas generated by pressure changes in the storage tank through a closed pipeline after the refueling machine completes the refueling action, avoiding direct discharge into the atmosphere. The system usually consists of a vacuum pump, return oil pipeline, oil and gas separator, and control unit. The key is to achieve high-precision oil and gas concentration detection and closed-loop control, ensuring stable operation under various working conditions and achieving emission targets.

However, there may still be trace amounts of oil and gas residue left after only one or two cycles of recovery. At this point, the supporting VOCs exhaust treatment device plays an important role. The device adopts a multi-stage collaborative purification process, with typical configurations including air cooling membrane components andactivated charcoalAdsorption unit. Firstly, the exhaust gas is pre cooled using air cooling membrane components to condense and precipitate some high boiling point hydrocarbons; Subsequently, it enters the activated carbon adsorption layer to efficiently capture the remaining low concentration volatile organic compounds. The entire process has no chemical reactions, does not produce secondary pollution, and operates safely and reliably.

In the selection of core technologies, emphasis should be placed on equipment integration and maintenance convenience. It is recommended to choose a combined device with a two-stage compression condensation+activated carbon adsorption dual purification path, which can achieve a processing efficiency of ≥ 95% and a recovery rate of>99%. Compared to a single adsorption or condensation method, this solution has strong adaptability, especially suitable for gas station scenarios with large temperature differences between day and night and frequent fluctuations in refueling loads. At the same time, modular design facilitates on-site installation and later replacement of filter materials, reducing downtime.

From the perspective of operational efficiency, an efficient tertiary oil and gas recovery system combined with a professional exhaust gas treatment device can not only completely solve the environmental risks caused by oil volatilization, but also significantly reduce oil loss. Taking a station with an average daily refueling volume of 3000 liters as an example, through system recycling, the annual average value of fuel saved can exceed 10000 yuan. In addition, the system automatically records operational data, supports remote monitoring and fault warning, greatly reduces the burden of manual inspection, and improves the level of intelligent operation and maintenance.

It is worth noting that equipment selection needs to be comprehensively evaluated based on the actual conditions of the site. For example, the volume of underground storage tanks, the number of refueling guns, geographical location and climate characteristics can all affect the system's compatibility. It is recommended to prioritize suppliers with local service support capabilities to ensure timely installation, debugging, regular maintenance, and emergency response.

Currently, an increasing number of gas stations have included upgrading their oil and gas recovery systems in their annual environmental renovation plans. This is not only a necessary measure to comply with regulatory trends, but also an opportunity to optimize asset structure and create long-term returns. Through scientific selection and standardized operation and maintenance, your site can not only achieve compliance and worry free, but also gain additional points in energy conservation, emission reduction, and brand reputation enhancement.
