硬核突破！沼气提纯“三脱”工艺显实力，中国制造护航中亚极寒能源安全

　　Hardcore breakthrough! The "three de" process of biogas purification demonstrates its strength, and Chinese manufacturing safeguards the energy security of extreme cold in Central Asia

　　沼气提纯作为生物质能源资源化利用的核心环节，直接决定沼气品质、利用效率及输送安全，而“三脱”（脱硫、脱水、脱烃）工艺更是沼气提纯的“生命线”，其技术水准直接关系到沼气能否实现规模化、安全化利用。随着全球沼气提纯市场的快速崛起，据行业数据显示，2024年全球沼气提纯净化设备市场规模达58.4亿元，预计2031年将突破146亿元，复合年增长率达14.1%，而“三脱”工艺的优化升级，正成为推动行业发展的核心动力。近日，发往哈萨克斯坦的天然气脱水脱氢装置顺利出征，在零下50℃极寒工况下实现稳定运行，彰显了中国制造在沼气提纯领域的硬核实力，也为中亚能源命脉注入新活力。

　　As the core link of biomass energy resource utilization, biogas purification directly determines the quality, utilization efficiency, and transportation safety of biogas. The "three de" (desulfurization, dehydration, and dehydrocarbon) process is the "lifeline" of biogas purification, and its technical level directly affects whether biogas can be used on a large scale and safely. With the rapid rise of the global biogas purification market, according to industry data, the market size of biogas purification equipment will reach 5.84 billion yuan in 2024, and is expected to exceed 14.6 billion yuan by 2031, with a compound annual growth rate of 14.1%. The optimization and upgrading of the "three de" process is becoming the core driving force for the development of the industry. Recently, the natural gas dehydration and dehydrogenation unit sent to Kazakhstan has been successfully deployed, achieving stable operation under extreme cold conditions of minus 50 ℃, demonstrating China's hard core strength in biogas purification and injecting new vitality into the energy lifeline of Central Asia.

　　沼气提纯的核心核心在于“三脱”工艺，三者各司其职、协同发力，缺一不可，共同守护沼气利用的安全与高效，这也是行业内公认的提纯核心标准。脱硫工艺作为第一道防线，核心作用是去除沼气中硫化氢等酸性气体，这类气体不仅具有强腐蚀性，会严重损耗提纯设备与输送管道，还会造成环境污染，甚至危害人体健康。正规沼气提纯项目中，脱硫工艺可将硫化氢含量降至10ppm以下，彻底杜绝腐蚀隐患，为后续提纯环节筑牢基础，这也是沼气提纯不可或缺的前置步骤。

　　The core of biogas purification lies in the "three de" process, where each plays its own role and works together to ensure the safety and efficiency of biogas utilization. This is also a recognized purification core standard in the industry. The desulfurization process, as the first line of defense, plays a core role in removing acidic gases such as hydrogen sulfide from biogas. These gases not only have strong corrosiveness and can seriously damage purification equipment and transmission pipelines, but also cause environmental pollution and even harm human health. In formal biogas purification projects, the desulfurization process can reduce the hydrogen sulfide content to below 10ppm, completely eliminating corrosion hazards and laying a solid foundation for subsequent purification processes. This is also an indispensable prerequisite for biogas purification.

　　脱水工艺是沼气提纯的关键环节，核心目标是降低沼气中的水含量，避免后续利用过程中出现水合物堵塞管道、设备腐蚀等问题。沼气中若含水量过高，在低温环境下易形成水合物，堵塞输送管道，导致系统停机，造成经济损失；同时，水分会加剧管道与设备的腐蚀，缩短使用寿命。优质脱水工艺可将沼气水含量降至10g/m?以下，即便在零下50℃极寒工况下，也能有效避免水合物生成，此次发往哈萨克斯坦的脱水脱氢装置，就凭借先进的脱水工艺，在极寒环境中实现稳定运行，印证了中国制造的可靠性。

　　Dehydration process is a key link in biogas purification, with the core goal of reducing the water content in biogas and avoiding problems such as hydrate blockage of pipelines and equipment corrosion during subsequent utilization. If the moisture content in biogas is too high, it is easy to form hydrates in low-temperature environments, which can block the transmission pipeline and cause system shutdown, resulting in economic losses; At the same time, moisture can exacerbate corrosion of pipelines and equipment, shortening their service life. Can high-quality dehydration technology reduce the water content of biogas to 10g/m? Even in extremely cold conditions of minus 50 ℃, the formation of hydrates can be effectively avoided. The dehydration and dehydrogenation unit sent to Kazakhstan has achieved stable operation in extremely cold environments with advanced dehydration technology, confirming the reliability of Chinese manufacturing.

　　脱烃工艺则聚焦沼气热值稳定与输送安全，核心是分离沼气中的重烃类物质。重烃类物质的存在会导致沼气热值波动，影响其作为清洁能源的利用效率，同时重烃易在管道内凝结，堵塞管道、引发安全隐患。脱烃工艺可精准分离重烃，将沼气热值稳定在35MJ/m?以上，确保沼气燃烧效率稳定，同时保障管道输送安全，为沼气规模化应用提供保障。值得一提的是，脱烃与脱水工艺协同配合，可进一步提升沼气提纯品质，满足工业、民用等多场景利用需求。

　　The dehydrogenation process focuses on the stability of biogas calorific value and transportation safety, with the core being the separation of heavy hydrocarbon substances in biogas. The presence of heavy hydrocarbons can cause fluctuations in the calorific value of biogas, affecting its efficiency as a clean energy source. At the same time, heavy hydrocarbons are prone to condense in pipelines, causing blockages and safety hazards. The dehydrogenation process can accurately separate heavy hydrocarbons and stabilize the calorific value of biogas at 35MJ/m? The above ensures stable combustion efficiency of biogas and guarantees safe pipeline transportation, providing assurance for the large-scale application of biogas. It is worth mentioning that the coordinated use of hydrocarbon and dehydration processes can further improve the quality of biogas purification and meet the needs of various industrial and civilian applications.

　　此次发往哈萨克斯坦的天然气脱水脱氢装置，是中国制造在沼气提纯领域的重要突破，其适配零下50℃极寒工况的核心能力，打破了国外技术垄断，彰显了我国沼气提纯设备的技术优势。该装置集成了先进的脱水、脱烃工艺，可应对中亚地区极端低温环境，确保沼气提纯过程稳定高效，不仅为哈萨克斯坦提供了可靠的能源提纯解决方案，也再次点亮了中亚能源命脉，推动我国沼气提纯技术与设备走向国际市场。

　　The natural gas dehydration and dehydrogenation unit sent to Kazakhstan this time is an important breakthrough in the field of biogas purification made in China. Its core ability to adapt to extremely cold working conditions of minus 50 ℃ breaks the monopoly of foreign technology and demonstrates the technological advantages of China's biogas purification equipment. This device integrates advanced dehydration and dehydrogenation processes, which can cope with extreme low temperature environments in Central Asia, ensuring stable and efficient biogas purification processes. It not only provides a reliable energy purification solution for Kazakhstan, but also once again illuminates the energy lifeline of Central Asia, promoting China's biogas purification technology and equipment to enter the international market.

　　当前，我国沼气提纯技术已日趋成熟，“三脱”工艺不断优化，结合变压吸附、膜分离等先进技术，提纯效率可达98%以上，提纯后的沼气可直接作为生物天然气投入使用，广泛应用于农业、工业、市政等领域。例如，黑龙江大庆寒地多物料连续干发酵项目，就通过完善的“三脱”提纯工艺，将沼气提纯为生物天然气，年生产377×10?Nm?，减排CO?1.28万吨，实现了环保与效益的双赢。

　　At present, China's biogas purification technology has become increasingly mature, and the "three de" process is continuously optimized. Combined with advanced technologies such as pressure swing adsorption and membrane separation, the purification efficiency can reach over 98%. The purified biogas can be directly used as bio natural gas and widely applied in agriculture, industry, municipal and other fields. For example, the multi material continuous dry fermentation project in the cold region of Daqing, Heilongjiang Province, uses a sophisticated "three de" purification process to purify biogas into bio natural gas, with an annual production of 377 × 10? Nm?， Reducing CO emissions by 12800 tons has achieved a win-win situation for environmental protection and benefits.

　　综上，沼气提纯的核心竞争力在于“三脱”工艺的成熟度与稳定性，脱硫防腐蚀、脱水防堵塞、脱烃保安全，三者协同发力，才能实现沼气的高效、安全、规模化利用。随着中国制造在沼气提纯领域的不断突破，不仅打破了国外技术壁垒，更推动我国生物质能源产业高质量发展，未来，凭借先进的“三脱”工艺与极寒适配能力，我国沼气提纯设备将在全球市场占据更重要的地位，为全球能源转型与环保事业贡献中国力量。

　　In summary, the core competitiveness of biogas purification lies in the maturity and stability of the "three de" process, which includes desulfurization, corrosion prevention, dehydration, blockage prevention, and hydrocarbon removal to ensure safety. Only by working together can efficient, safe, and large-scale utilization of biogas be achieved. With the continuous breakthroughs of Chinese manufacturing in the field of biogas purification, it not only breaks through foreign technological barriers, but also promotes the high-quality development of China's biomass energy industry. In the future, with advanced "three de" processes and extreme cold adaptation capabilities, China's biogas purification equipment will occupy a more important position in the global market, contributing Chinese strength to the global energy transformation and environmental protection cause.
