　　Unveiling the lifespan of the membrane in the three oil and gas recovery equipment! 8 and a half years of actual testing to meet standards, bidding farewell to carbon adsorption secondary pollution and frequent pit replacement

　　三次油气回收设备作为加油站、储油库等油气储运场景的核心环保装备，其性能稳定性与使用寿命直接关系到VOCs排放达标、环保合规及运营成本控制。而膜组件作为膜结构三次油气回收设备的核心部件，“使用寿命多久、是否易损坏、后期维护成本高不高”，成为众多企业采购与使用中的核心疑问。据油气环保行业调研数据显示，69%的企业在选购三次油气回收设备时，最关注膜组件寿命，其中52%因担心膜组件易损坏、频繁更换，仍在犹豫是否放弃传统碳吸附设备。今天，结合行业实践与实测数据，全面解析三次油气回收设备膜组件的使用寿命、核心优势，对比碳吸附与膜结构设备的差异，帮企业避开选型误区，读懂膜结构设备的长效价值。

　　As the core environmental protection equipment for oil and gas storage and transportation scenarios such as gas stations and oil depots, the performance stability and service life of the tertiary oil and gas recovery equipment are directly related to the compliance of VOCs emissions, environmental protection, and operational cost control. As the core component of the membrane structure tertiary oil and gas recovery equipment, membrane components have become the core questions for many enterprises in procurement and use, such as their service life, susceptibility to damage, and high maintenance costs in the later stage. According to research data from the oil and gas environmental protection industry, 69% of companies are most concerned about the lifespan of membrane components when purchasing tertiary oil and gas recovery equipment. Among them, 52% are still hesitating whether to give up traditional carbon adsorption equipment due to concerns about membrane component damage and frequent replacement. Today, based on industry practice and measured data, we will comprehensively analyze the service life and core advantages of membrane components in tertiary oil and gas recovery equipment, compare the differences between carbon adsorption and membrane structure equipment, help enterprises avoid selection errors, and understand the long-term value of membrane structure equipment.

　　在三次油气回收技术发展过程中，碳吸附工艺曾是主流选择，但随着环保标准日趋严格，其固有的弊端逐渐凸显，也推动了膜结构三次油气回收设备的广泛应用。根据《加油站大气污染物排放标准》（GB20952—2020）要求，新建加油站三次油气回收设备排放浓度需≤10g/m?，现有加油站也需在2026年11月前达到该标准，而传统碳吸附三次油气回收设备，不仅存在废碳处理难题，还常出现排放不达标、维护繁琐等问题，已难以适配当前环保要求。

　　In the development process of tertiary oil and gas recovery technology, carbon adsorption process was once the mainstream choice. However, with the increasingly strict environmental standards, its inherent drawbacks have gradually become prominent, which has also promoted the widespread application of membrane structure tertiary oil and gas recovery equipment. According to the "Emission Standards for Air Pollutants from Gas Stations" (GB20952-2020), the emission concentration of the tertiary oil and gas recovery equipment at newly built gas stations must be ≤ 10g/m? Existing gas stations also need to meet this standard by November 2026, and traditional carbon adsorption tertiary oil and gas recovery equipment not only faces the problem of waste carbon treatment, but also often encounters issues such as emissions not meeting standards and complicated maintenance, making it difficult to adapt to current environmental requirements.

　　传统碳吸附三次油气回收设备的核心痛点，集中在环保性与维护成本上。碳吸附工艺依靠活性炭吸附油气中的烃类物质，吸附饱和后需定期更换活性炭，更换周期一般不超过1年，而更换下来的废碳属于危险废物，处置流程复杂、成本高昂，给企业带来额外的环保压力与经济负担；更关键的是，碳吸附设备的净化效率有限，长期使用后易出现吸附饱和不彻底的情况，导致排放气体不达标，企业可能面临环保处罚，同时也无法有效控制油气损耗。

　　The core pain points of traditional carbon adsorption tertiary oil and gas recovery equipment are focused on environmental friendliness and maintenance costs. The carbon adsorption process relies on activated carbon to adsorb hydrocarbon substances in oil and gas. After adsorption saturation, the activated carbon needs to be replaced regularly, with a replacement cycle generally not exceeding one year. The replaced waste carbon belongs to hazardous waste, and the disposal process is complex and costly, bringing additional environmental pressure and economic burden to enterprises; More importantly, the purification efficiency of carbon adsorption equipment is limited, and after long-term use, it is prone to incomplete adsorption saturation, resulting in emissions that do not meet standards. Enterprises may face environmental penalties and cannot effectively control oil and gas losses.

　　正是基于碳吸附设备的诸多弊端，膜结构三次油气回收设备逐渐成为行业主流，其核心优势在于环保、高效、长效，尤其膜组件的使用寿命远超传统吸附剂，彻底解决了频繁更换、维护繁琐的痛点。膜结构三次油气回收设备采用高分子膜分离技术，利用特殊高分子膜对油气分子与空气分子的选择性渗透性，实现油气与空气的高效分离，高浓度油气可回收至储油罐循环利用，净化后的空气则达标排放，整个过程无废水废渣产生，无二次污染隐患，完美契合绿色环保发展理念。

　　It is precisely based on the many drawbacks of carbon adsorption equipment that membrane structure tertiary oil and gas recovery equipment has gradually become the mainstream of the industry. Its core advantages lie in environmental protection, high efficiency, and long-term effectiveness, especially the service life of membrane components far exceeds that of traditional adsorbents, completely solving the pain points of frequent replacement and tedious maintenance. The membrane structure tertiary oil and gas recovery equipment adopts polymer membrane separation technology, which utilizes the selective permeability of special polymer membranes for oil and gas molecules and air molecules to achieve efficient separation of oil and gas from air. High concentration oil and gas can be recovered and reused in oil storage tanks, and purified air can be discharged in compliance with standards. The entire process produces no wastewater or waste residue, and there is no hidden danger of secondary pollution, perfectly in line with the concept of green environmental protection development.

　　关于企业最关心的“三次油气回收设备膜组件能用多久”这一核心问题，从技术原理与实际实测数据两方面，可给出明确答案。从理论层面来看，膜组件的分离过程基于溶解扩散机理，油气分子通过膜组件时，仅发生物理分离，不会与膜材质发生化学反应，也不会对膜结构造成损伤或损坏，理论上可实现长期稳定使用，无需频繁更换。

　　Regarding the core question that enterprises are most concerned about, 'How long can the membrane components of the tertiary oil and gas recovery equipment last?', a clear answer can be given from both technical principles and actual measured data. From a theoretical perspective, the separation process of membrane components is based on the dissolution diffusion mechanism. When oil and gas molecules pass through the membrane components, they only undergo physical separation and do not react chemically with the membrane material, nor do they cause damage or destruction to the membrane structure. In theory, it can achieve long-term stable use without frequent replacement.

　　从实际应用实测来看，我们最早安装的膜结构三次油气回收设备，至今已稳定运行8年半，经专业检测，其排放的油气浓度始终控制在10g/m?以下，完全符合国家环保标准，膜组件无破损、无衰减，依然保持良好的分离性能。结合行业数据来看，优质膜结构三次油气回收设备的膜组件，正常运行情况下使用寿命可达8-10年，部分优质进口膜材甚至可达到更长使用年限，远超传统碳吸附设备活性炭1年左右的更换周期，大幅降低企业后期维护与更换成本。

　　From actual application tests, it can be seen that our earliest installed membrane structure tertiary oil and gas recovery equipment has been running stably for 8 and a half years. After professional testing, its discharged oil and gas concentration has always been controlled at 10g/m? The following fully complies with national environmental standards, with no damage or attenuation to the membrane components, and still maintains good separation performance. Based on industry data, the membrane components of high-quality membrane structure tertiary oil and gas recovery equipment can have a service life of 8-10 years under normal operation, and some high-quality imported membrane materials can even have a longer service life, far exceeding the traditional carbon adsorption equipment's activated carbon replacement cycle of about 1 year, significantly reducing the maintenance and replacement costs of enterprises in the later stage.

　　膜组件之所以能实现长期稳定使用，核心在于其材质特性与工艺优势。优质膜组件采用专用高分子材料制成，具备优异的耐油气腐蚀、抗老化性能，可适应油气储运场景的复杂工况，同时膜结构三次油气回收设备采用撬装式设计，结构紧凑、操作便捷，系统可实现自动启停控制，当储油罐压力达到设定值时自动启动，压力降至合理范围后自动停止，减少膜组件的无效损耗，进一步延长其使用寿命。此外，膜结构设备的油气回收率可达99%以上，单位能耗低，不仅能实现环保达标，还能有效回收油气资源，为企业降低能源损耗。

　　The reason why membrane components can achieve long-term stable use lies in their material characteristics and process advantages. High quality membrane components are made of special polymer materials, which have excellent oil and gas corrosion resistance and aging resistance, and can adapt to the complex working conditions of oil and gas storage and transportation scenarios. At the same time, the membrane structure tertiary oil and gas recovery equipment is skid mounted, which is compact in structure and easy to operate. The system can realize automatic start and stop control. When the pressure of the oil tank reaches the set value, it will automatically start, and when the pressure drops to a reasonable range, it will automatically stop, so as to reduce the invalid loss of the membrane components and further extend their service life. In addition, the oil and gas recovery rate of membrane structure equipment can reach over 99%, with low unit energy consumption. It not only meets environmental standards but also effectively recovers oil and gas resources, reducing energy consumption for enterprises.

　　需要特别说明的是，膜组件的使用寿命也与设备的日常维护、预处理工艺密切相关。膜结构三次油气回收设备对油气的预处理（除液、除尘）要求严格，若预处理不到位，油气中的杂质可能附着在膜表面，影响分离效果与膜组件寿命。因此，企业在使用过程中，只需按照规范做好日常维护，每周检查设备密封性，每月对排气口进行采样监测，每季度校准控制系统，即可确保膜组件长期稳定运行，无需额外投入大量维护成本。

　　It should be noted that the service life of membrane components is closely related to the daily maintenance and pretreatment processes of the equipment. The membrane structure tertiary oil and gas recovery equipment has strict requirements for the pre-treatment of oil and gas (liquid removal, dust removal). If the pre-treatment is not in place, impurities in the oil and gas may adhere to the membrane surface, affecting the separation effect and membrane component life. Therefore, in the process of use, enterprises only need to carry out daily maintenance according to the specifications, check the sealing of equipment every week, sample and monitor the exhaust port every month, and calibrate the control system every quarter to ensure the long-term stable operation of membrane components without the need for additional maintenance costs.

　　对比传统碳吸附设备与膜结构设备，两者的差距十分明显：碳吸附设备需每年更换活性炭，废碳处置成本高，排放易不达标，维护繁琐；而膜结构设备膜组件使用寿命可达8-10年，无二次污染，排放稳定达标，维护简单，长期使用下来，可为企业节省大量的维护与更换成本，同时规避环保处罚风险。尤其在当前环保监管日趋严格的背景下，膜结构三次油气回收设备已成为企业实现环保合规、降本增效的最优选择。

　　Compared with traditional carbon adsorption equipment and membrane structure equipment, the difference between the two is very obvious: carbon adsorption equipment requires annual replacement of activated carbon, high cost of waste carbon disposal, easy non-compliance with emissions standards, and tedious maintenance; The service life of membrane components in membrane structure equipment can reach 8-10 years, with no secondary pollution, stable emission standards, simple maintenance, and long-term use, which can save enterprises a lot of maintenance and replacement costs while avoiding environmental penalties. Especially in the context of increasingly strict environmental regulations, membrane structured tertiary oil and gas recovery equipment has become the optimal choice for enterprises to achieve environmental compliance, cost reduction, and efficiency improvement.

　　很多企业在选购三次油气回收设备时，仍会被“膜组件寿命短、易损坏”的不实传言误导，迟迟不敢更换膜结构设备。事实上，经过多年行业实践验证，膜结构三次油气回收设备的膜组件具有长效耐用、稳定可靠的特点，8年半的实测数据也充分证明了其使用寿命与性能稳定性。选择优质膜结构三次油气回收设备，不仅能满足环保排放要求，还能减少后期维护麻烦，降低运营成本，实现环保与效益的双赢。

　　Many companies are still misled by false rumors of "short lifespan and easy damage of membrane components" when purchasing tertiary oil and gas recovery equipment, and hesitate to replace membrane structure equipment. In fact, after years of industry practice verification, the membrane components of the membrane structure tertiary oil and gas recovery equipment have the characteristics of long-term durability, stability and reliability. The 8-and-a-half-year measured data also fully proves their service life and performance stability. Choosing high-quality membrane structure tertiary oil and gas recovery equipment can not only meet environmental emission requirements, but also reduce maintenance troubles in the later stage, lower operating costs, and achieve a win-win situation of environmental protection and benefits.
