　　Solve the confusion! How long can the membrane structure of oil and gas recovery equipment last? Tested for over 8 years and still meeting standards, oil and gas recovery equipment is an indispensable environmental protection equipment in fields such as petroleum retail and oil storage. Its core function is to recover oil and gas, control volatile organic compound (VOCs) emissions, and comply with the strict requirements of the "Gas Station Air Pollutant Emission Standards" (GB20952-2020). Among them, membrane structure, as the mainstream configuration of current tertiary oil and gas recovery equipment, has always been the core concern of industry practitioners in terms of its service life - after all, the frequency of equipment consumables replacement directly affects operating costs and environmental compliance efficiency. According to industry research data, 75% of oil and gas recovery equipment users are most concerned about the durability of membrane structures when selecting, and the many drawbacks of previous carbon adsorption processes have also made membrane structures a better choice. Today, based on actual test data and industry experience, we will explain in detail the service life and core advantages of the membrane structure of oil and gas recovery equipment, helping practitioners to accurately avoid pitfalls and reduce operating costs.

　　在膜结构油气回收设备普及之前，行业内主流的三次油气回收设备多采用碳吸附工艺，这种工艺虽曾广泛应用，但存在难以规避的两大痛点，逐渐被市场淘汰。一方面，碳吸附工艺产生的废碳处理难度大，易造成二次污染，不符合绿色环保的行业发展趋势；另一方面，碳吸附设备的油气处理精度有限，排放气体经常达不到国家规定的10g/m?排放标准，导致企业面临环保处罚风险，据统计，采用碳吸附工艺的设备，环保达标率仅为72%，每年有近30%的企业因排放不达标被责令整改。

　　Before the popularization of membrane structure oil and gas recovery equipment, the mainstream tertiary oil and gas recovery equipment in the industry mostly used carbon adsorption technology. Although this technology was widely used, there were two major pain points that were difficult to avoid, and it was gradually eliminated by the market. On the one hand, the waste carbon generated by carbon adsorption technology is difficult to treat and can easily cause secondary pollution, which does not conform to the trend of green and environmentally friendly industry development; On the other hand, the oil and gas treatment accuracy of carbon adsorption equipment is limited, and the emission gas often does not reach the national standard of 10g/m? The emission standards pose a risk of environmental penalties for enterprises. According to statistics, the environmental compliance rate of equipment using carbon adsorption technology is only 72%, and nearly 30% of enterprises are ordered to rectify their emissions every year due to non-compliance.

　　正是基于碳吸附工艺的诸多弊端，膜结构油气回收设备逐渐成为行业主流，被广泛应用于加油站、储油库等场景。与碳吸附工艺不同，膜结构油气回收设备采用特殊高分子膜对油气分子进行选择性渗透分离，其核心优势之一就是膜结构的高耐用性——从理论实验来看，油气分子通过膜结构时，不会对膜的材质造成损伤或损坏，无需频繁更换，可实现长期稳定运行，这也是膜结构区别于碳吸附工艺的核心竞争力。

　　Due to the many drawbacks of carbon adsorption technology, membrane structure oil and gas recovery equipment has gradually become the mainstream of the industry and is widely used in scenarios such as gas stations and oil storage tanks. Unlike carbon adsorption processes, membrane structure oil and gas recovery equipment uses special polymer membranes for selective permeation and separation of oil and gas molecules. One of its core advantages is the high durability of the membrane structure. From theoretical experiments, when oil and gas molecules pass through the membrane structure, they will not cause damage or destruction to the membrane material, and do not need to be replaced frequently. It can achieve long-term stable operation, which is also the core competitiveness of the membrane structure compared to carbon adsorption processes.

　　膜结构的耐用性并非理论空谈，而是经过长期实际应用验证的。根据我们的实测数据，最早安装的一批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，其油气排放浓度仍远低于国家标准，回收效率保持在99%以上，膜结构无任何破损、老化现象，依然能正常发挥油气分离、回收作用。这一实测数据，也印证了膜结构的长期耐用性，远超行业内部分从业者的预期。

　　The durability of membrane structures is not just theoretical talk, but has been verified through long-term practical applications. According to our actual measurement data, the first batch of membrane structure tertiary oil and gas recovery equipment installed has been running stably for 8 and a half years. After professional testing, its oil and gas emission concentration is still far below the national standard, and the recovery efficiency remains above 99%. The membrane structure has no damage or aging, and can still function normally for oil and gas separation and recovery. This measured data also confirms the long-term durability of membrane structures, far exceeding the expectations of some practitioners in the industry.

　　从行业标准来看，《油气回收处理设施技术标准》（GB/T50759-2022）明确规定，分离膜组件的设计使用寿命不应低于8年，而优质膜结构通过科学维护，使用寿命可进一步延长至10年以上。这是因为膜结构采用耐油气、抗老化的专用高分子材料，经过特殊工艺处理，具备优异的稳定性，可耐受油气环境的长期侵蚀，不会因油气分子的渗透而出现破损、失效，从根本上解决了碳吸附工艺耗材频繁更换的痛点。

　　From the perspective of industry standards, the "Technical Standards for Oil and Gas Recovery and Treatment Facilities" (GB/T50759-2022) clearly stipulate that the design service life of separation membrane components should not be less than 8 years, while high-quality membrane structures can be further extended to a service life of more than 10 years through scientific maintenance. This is because the membrane structure uses special polymer materials that are resistant to oil and gas and aging. After special processing, it has excellent stability, can withstand the long-term erosion of oil and gas environment, and will not be damaged or invalid due to the penetration of oil and gas molecules. This fundamentally solves the problem of frequent replacement of carbon adsorption process consumables.

　　很多从业者会担心，长期使用后膜结构的分离效率会下降、排放会不达标，但实际应用数据表明，这种顾虑大可不必。优质膜结构油气回收设备，通过定期简单维护（如清洁膜表面杂质），可始终保持稳定的分离性能，其油气处理回收率长期维持在95%以上，排放浓度严格符合国家及地方环保限值。相较于碳吸附设备每2年左右就需更换一次活性炭，膜结构8-10年无需更换，可大幅降低企业的耗材更换成本与人工维护成本。

　　Many practitioners may worry that the separation efficiency of membrane structures will decrease and emissions will not meet standards after long-term use, but actual application data shows that such concerns are unnecessary. High quality membrane structure oil and gas recovery equipment can maintain stable separation performance through regular simple maintenance (such as cleaning membrane surface impurities). Its oil and gas treatment recovery rate remains above 95% for a long time, and the emission concentration strictly meets national and local environmental protection limits. Compared to carbon adsorption equipment that needs to replace activated carbon every 2 years, membrane structures do not need to be replaced for 8-10 years, which can significantly reduce the cost of consumable replacement and manual maintenance for enterprises.

　　据行业成本测算，一台膜结构三次油气回收设备，膜组件的一次性投入虽比碳吸附耗材略高，但长期来看，8年周期内的综合维护成本比碳吸附设备低60%以上，且可避免因排放不达标造成的环保处罚，间接为企业节省大量开支。此外，膜结构油气回收设备还具备能耗低、无二次污染的优势，单位能耗远低于0.2kW?h/m?，契合绿色低碳的发展理念，成为当前油气回收领域的优选方案。

　　According to industry cost estimates, for a membrane structure tertiary oil and gas recovery equipment, although the one-time investment in membrane components is slightly higher than that of carbon adsorption consumables, in the long run, the comprehensive maintenance cost within an 8-year cycle is more than 60% lower than that of carbon adsorption equipment, and it can avoid environmental penalties caused by non compliant emissions, indirectly saving a lot of expenses for the enterprise. In addition, membrane structure oil and gas recovery equipment also has the advantages of low energy consumption and no secondary pollution, with a unit energy consumption far below 0.2 kW · h/m? In line with the development concept of green and low-carbon, it has become the preferred solution in the current field of oil and gas recovery.

　　需要注意的是，膜结构的使用寿命也与设备选型、日常维护密切相关。优质的膜组件采用进口或国内知名品牌的高分子材料，经严格检测合格后投入使用，耐用性更有保障；而劣质膜组件材质不佳，不仅使用寿命会缩短至3-5年，还可能出现分离效率下降、排放超标等问题。因此，从业者在选型油气回收设备时，不仅要关注膜结构的使用寿命，更要选择正规厂家生产的优质膜组件，同时做好日常维护，才能充分发挥膜结构的优势。

　　It should be noted that the service life of membrane structures is also closely related to equipment selection and daily maintenance. High quality membrane components are made of imported or well-known domestic brands of polymer materials, which are rigorously tested and qualified before being put into use, ensuring greater durability; Poor quality membrane module materials not only shorten the service life to 3-5 years, but also may cause problems such as decreased separation efficiency and excessive emissions. Therefore, when selecting oil and gas recovery equipment, practitioners should not only pay attention to the service life of the membrane structure, but also choose high-quality membrane components produced by regular manufacturers, and do a good job in daily maintenance, in order to fully utilize the advantages of the membrane structure.

　　综上，油气回收设备膜结构的使用寿命远超行业预期，理论上可长期稳定运行，实测数据显示其使用寿命可达8年以上，且经科学维护可延长至10年+，排放始终符合国家标准。膜结构的普及，不仅解决了碳吸附工艺的环保与达标痛点，更帮助企业降低了运营成本，实现了环保与效益的双赢。对于仍在纠结膜结构使用寿命、担心频繁更换耗材的从业者而言，选择优质膜结构油气回收设备，无疑是省心、 经济的选择，既能满足环保要求，又能减少后期维护麻烦，助力企业合规、高效运营。

　　In summary, the service life of the membrane structure of oil and gas recovery equipment far exceeds industry expectations. Theoretically, it can operate stably for a long time. Actual test data shows that its service life can reach more than 8 years, and after scientific maintenance, it can be extended to more than 10 years. The emissions always meet national standards. The popularization of membrane structures not only solves the environmental and compliance pain points of carbon adsorption processes, but also helps enterprises reduce operating costs and achieve a win-win situation of environmental protection and benefits. For practitioners who are still struggling with the service life of membrane structures and worried about frequent replacement of consumables, choosing high-quality membrane structure oil and gas recovery equipment is undoubtedly a worry free and economical choice. It can meet environmental requirements, reduce maintenance troubles in the later stage, and help enterprises operate in compliance and efficiently.
