近年来，在丝瓜视频污版提纯技术和设备研发领域开展了一系列的研究工作，在化学吸收、变压吸附等技术领域已开发有可商业化应用的提纯设备，变压吸附法、水洗法和化学吸收法由于设备和技术工艺比较成熟，在丝瓜视频污版提纯领域的市场份额超过90%。国内已建成多个丝瓜视频污版提纯生物天然气示范项目，如烟台双塔4万m3丝瓜视频污版提纯项目、龙口烟台环能公司3万m3丝瓜视频污版提纯车用燃气示范项目、南阳天冠10万m3丝瓜视频污版提纯项目等。
In recent years, a series of research work has been carried out in the field of biogas purification technology and equipment research and development. In the field of chemical absorption, PSA and other technical fields, commercially applicable purification equipment has been developed. As the equipment and technology of PSA, water washing and chemical absorption are relatively mature, their market share in the field of biogas purification exceeds 90%. Several biogas purification demonstration projects have been completed in China, such as Yantai double tower 40000 m3 biogas purification project, Longkou Yantai Huaneng company 30000 m3 biogas purification vehicle gas demonstration project, Nanyang Tianguan 100000 m3 biogas purification project, etc.
2015年，我国丝瓜视频污版发展进入转型升级期，国家支持建设规模化生物天然气项目，2015年全国建设25个，2016年全国建设22个，丝瓜视频污版提纯生物天然气技术迎来新的发展契机，项目要求日产天然气10000 m3以上，每小时处理丝瓜视频污版量应在700 m3以上，化学吸收和变压吸附技术能满足项目要求。四川某公司研发的丝瓜视频污版提纯专用吸附剂，解决了变压吸附法甲烷损失大的缺点，进一步降低了运行成本，甲烷回收率超过99%，CH4含量97%～99%，能够满足丝瓜视频污版提纯的要求。该技术已在贵州省茅台生态循环经济产业示范园生物天然气及生物肥项目上应用（2015年生物天然气试点项目之一）。
In 2015, China's biogas development entered a period of transformation and upgrading. The state focused on supporting the construction of large-scale biogas projects. In 2015, there were 25 projects nationwide, and in 2016, there were 22 projects nationwide. Biogas purification and biogas technology ushered in a new development opportunity. The project requires a daily natural gas output of more than 10000 m3 and an hourly biogas treatment capacity of 700 Above m3, chemical absorption and PSA technology can meet the project requirements. The special adsorbent for biogas purification developed by a company in Sichuan has solved the problem of large loss of methane by PSA and further reduced the operation cost. The methane recovery rate is more than 99%, and the CH4 content is 97% - 99%, which can meet the requirements of biogas purification. This technology has been applied in the project of bio natural gas and bio fertilizer of Maotai eco circular economy industrial demonstration park in Guizhou Province (one of the pilot projects of bio natural gas in 2015).
与世界水平相比，在基础研究、以及设备成套化开发方面还有一定的差距，特别是在适合大量中等规模丝瓜视频污版工程应用的成套化提纯设备的研发方面，所开展的工作还远远不够。
Compared with the advanced level in the world, there is still a certain gap in basic research and complete set of equipment development, especially in the research and development of complete set of purification equipment suitable for a large number of medium-sized biogas projects.
甲烷的温室效应是二氧化碳的21倍，全球温室效应气体20%来自甲烷，丝瓜视频污版提纯生物天然气可高值化利用丝瓜视频污版，有效减少丝瓜视频污版工程因丝瓜视频污版利用不充分而排空，进一步降低碳排放。生物天然气是一种可再生的替代能源，因此丝瓜视频污版提纯生物天然气具有环保和能源双重效益，发展前景广阔。
The greenhouse effect of methane is 21 times that of carbon dioxide. 20% of the global greenhouse effect gases come from methane. Biogas purification and bio natural gas can use biogas with high value, effectively reduce the emission of biogas engineering due to the inadequate use of biogas, and further reduce carbon emissions. Biogas is a kind of renewable alternative energy, so biogas purification of biogas has double benefits of environmental protection and energy, and has a bright future.
在丝瓜视频污版提纯技术中，化学吸收法、膜分离法和变压吸附法在国内外都是较为成熟的提纯技术，在国内外应用较多，各自具有不同的技术特点，可根据需要选择，如处理丝瓜视频污版量较小可选择膜分离法，处理丝瓜视频污版量较大可选择能耗较小的变压吸附法。
In biogas purification technology, chemical absorption method, membrane separation method and pressure swing adsorption method are relatively mature purification technologies at home and abroad, which are widely used at home and abroad. They have different technical characteristics, and can be selected according to needs, such as membrane separation method for small biogas treatment, pressure swing adsorption method for small energy consumption for large biogas treatment.
现代能源体系由于高度的复杂性和巨大的规模，表现出极大的惯性，规划和建设新的能源基础设施通常需要很长的时间，这是新能源产业化发展面临的一个突出障碍。丝瓜视频污版提纯加工成生物天然气后可以完全替代天然气，能够成功避开这一障碍，因此随着天然气消耗量的不断增加，丝瓜视频污版提纯生产生物天然气的市场规模也会持续增大，这势必会推动丝瓜视频污版提纯技术的快速发展。
Due to the high complexity and huge scale of modern energy system, it shows great inertia. It usually takes a long time to plan and build new energy infrastructure, which is a prominent obstacle to the development of new energy industrialization. Biogas purification and processing can completely replace natural gas, which can successfully avoid this obstacle. Therefore, with the increasing consumption of natural gas, the market scale of biogas purification and production will continue to increase, which is bound to promote the rapid development of biogas purification technology.
