Biogas series technology is a type of green ecological technology that transforms decay into magic. The current important trend of this type of technology is "resource utilization", and it naturally relies on strong support from new technologies. Today, the editor of Chain Technology will focus on introducing a chain technology achievement library project called "High performance hollow fiber biogas separation membrane".

我们知道，沼气是有机物质在厌氧条件下，经过微生物的发酵作用而生成的一种可燃气体。沼气是多种气体的混合物，一般含甲烷50～70%，其余为二氧化碳和少量的氮、氢和硫化氢等。其特性与天然气相似。空气中如含有8.6～20.8%体积的沼气，就可能形成燃气爆炸。就用途而言，沼气主要用作燃料，近年来沼气发电、沼气电池的研究也被推上前台。

We know that biogas is a combustible gas generated by the fermentation of organic matter under anaerobic conditions by microorganisms. Biogas is a mixture of various gases, generally containing 50-70% methane, while the rest is carbon dioxide and a small amount of nitrogen, hydrogen, and hydrogen sulfide. Its characteristics are similar to natural gas. If the air contains 8.6 to 20.8% volume of biogas, it may form a gas explosion. In terms of usage, biogas is mainly used as fuel, and in recent years, research on biogas power generation and biogas batteries has also been promoted to the forefront.

再介绍一点有关沼气技术的有趣故事，那就是沼气技术的发展历程。沼气的历史毋庸多言，它应该比人类还早，但沼气的定义及技术却出现很晚。沼气现代意义上的明确定义由意大利物理学家A.沃尔塔于1776年在沼泽地发现并完成。

Another interesting story about biogas technology is the development process of biogas technology. The history of biogas goes without saying, it should have been earlier than humans, but the definition and technology of biogas emerged very late. The clear definition of biogas in the modern sense was discovered and completed by Italian physicist A. Wardha in the marsh in 1776.

链科技成果库项目：高性能中空纤维沼气分离膜。高性能中空纤维沼气分离膜及膜法沼气提纯制压缩天然气。与传统分离方法相比，膜分离过程具有设备体积小、能耗低、投资低、操作维修便捷等优点，更为重要的是膜分离技术也更加安全， 容易规模化放大，不添加额外的有害化学物质，再处理规模不太大，而且二氧化碳含量较高的yl6809永利过程中更具优势。

Chain Technology Achievement Library Project: High performance hollow fiber biogas separation membrane. High performance hollow fiber biogas separation membrane and membrane biogas purification to produce Compressed natural gas. Compared with traditional separation methods, membrane separation process has advantages such as small equipment volume, low energy consumption, low investment, and convenient operation and maintenance. More importantly, membrane separation technology is also safer, easy to scale up, does not add additional harmful chemicals, and does not have a large reprocessing scale. Moreover, biogas purification processes with high carbon dioxide content have more advantages.

膜分离法提纯沼气可以使产品气甲烷浓度达到 95%以上，回收率高于92%。而且与水洗、吸收等方法相比，无需大量水或化学吸收剂，操作压力低，对外部环境要求低，并且为模块化系统，在气源枯竭或需要另外选址时，容易搬迁移动。

The membrane separation method for purifying biogas can achieve a methane concentration of over 95% in the product gas and a recovery rate of over 92%. Moreover, compared to methods such as water washing and absorption, it does not require a large amount of water or chemical absorbents, has low operating pressure, low requirements for the external environment, and is a modular system, making it easy to relocate and move when the gas source is depleted or another location needs to be selected.
