生物天然气是以农作物秸秆、畜禽粪污、餐厨垃圾、农副产品加工废水等各类城乡有机废弃物为原料，经厌氧发酵和净化提纯产生的绿色低碳清洁可再生的天然气，同时厌氧发酵过程中产生的沼渣沼液可生产有机肥。
Biological natural gas is a green, low-carbon, clean and renewable natural gas produced by anaerobic fermentation, purification and purification with various urban and rural organic wastes such as crop straw, livestock and poultry manure, kitchen waste and agricultural and sideline product processing wastewater as raw materials. At the same time, the biogas residue and biogas liquid produced in the process of anaerobic fermentation can produce organic fertilizer.
沼气的主要成分是CH4和CO2，将CO2从混合气中分离得到的高纯度甲烷气被称为生物天然气。生物天然气可以直接作为石化天然气的替代燃料，发展沼气已成为增加天然气供应量的一个重要方向。人类对天然气需求量的增加推动了生物天然气技术的发展。沼气提纯生物天然气可高值化利用沼气，有效减少沼气工程因沼气利用不充分而排空造成的温室效应，具有环保和能源双重效益。。
The main components of biogas are CH4 and CO2. The high-purity methane gas obtained by separating CO2 from the mixture is called biological natural gas. Biogas can be directly used as an alternative fuel for Petrochemical Natural gas. The development of biogas has become an important direction to increase the supply of natural gas. The increase of human demand for natural gas promotes the development of biological natural gas technology. Biogas purification of biological natural gas can make high-value use of biogas, effectively reduce the greenhouse effect caused by the emptying of biogas project due to insufficient utilization of biogas, and has the dual benefits of environmental protection and energy..

Four new anaerobic fermentation units, straw storage shed, pump house, double membrane gas storage tank, natural gas compression plant, CNG filling station building, organic fertilizer processing, biogas residue and biogas liquid temporary storage tank, wastewater treatment tank and other projects are to be built, and 92 sets of straw chopper, grass grabber, loader, solid feeding system, pneumatic conveying tank, biogas liquid circulating tank and other instruments and equipment are to be purchased.
规模化生物天然气试点项目充分利用了秸秆等农业生产剩余物，实现了废弃资源的多层次循环利用，对于发展生态循环农业有着重要的意义。项目有利于扩大农民就业、增加农民收入，而且还能保护生态环境、改善居民生活条件，经济效益、生态效益和社会效益十分明显。
The large-scale bio natural gas pilot project makes full use of agricultural production residues such as straw and realizes the multi-level recycling of waste resources, which is of great significance for the development of ecological circular agriculture. The project not only helps to expand farmers' employment and increase farmers' income, but also protects the ecological environment and improves residents' living conditions. The economic, ecological and social benefits are very obvious.
解决方案
Solution
该项目需要对天然气提纯前后的甲烷CH4、二氧化碳CO2、硫化氢H2S气体含量进行实时在线监测，从而调整相应的工艺，提高天然气提纯的纯度，增加产业效益。
The project requires real-time online monitoring of methane CH4, carbon dioxide CO2, hydrogen sulfide and H2S before and after natural gas purification, so as to adjust the corresponding process, improve the purity of natural gas purification and increase industrial benefits.
