In recent years, with the increasing pressure of global resource storage and environmental governance, more and more biogas purification projects have been constructed, which is in line with the current situation of new energy development and utilization of new resources, and is the inevitable direction of future energy development. Why is that?

　　1、符合全球环境而可持续发展政策，是开展可再生能源、改善能源构造的需求。

　　1. The sustainable development policy in line with the global environment is the demand of developing renewable energy and improving energy structure.

　　目前，我国已成为第二大能源消费国，化石燃料的消费和运用引起重的温室效应、酸雨、毁坏臭氧层等环境问题。沼气提纯推进能源消费构造和应用方式革新，推进能源多元清洁开展。生物天然气作为一种清洁的气体能源，以其循环环保、变“废”为“宝”、副产品可应用、技术成熟易推行等特性，在新能源利用方面大有作为。

　　At present, China has become the second largest energy consumption country. The consumption and utilization of fossil fuels cause serious environmental problems such as greenhouse effect, acid rain, and destruction of ozone layer. Biogas purification promotes the innovation of energy consumption structure and application mode, and promotes the diversified and clean development of energy. As a kind of clean gas energy, bio natural gas has great potential in the utilization of new energy due to its characteristics of recycling environmental protection, changing "waste" into "treasure", by-product application, mature technology and easy implementation.
                 

　　2、延长产业链，提升附加值，进步企业竞争力。

　　2. To extend the industrial chain, enhance the added value and improve the competitiveness of enterprises.

　　能源企业竞争激烈，经过提纯制取生物天然气，能够延长企业产品产业链，提升产品附加值，是企业提升竞争力的有效手段之一。

　　The competition of energy companies is fierce. After purification and preparation of bio natural gas, the industrial chain of products can be extended and the added value of products can be enhanced. It is one of the effective means for enterprises to enhance competitiveness.

　　3、减少温室气体排放的需求。

　　3. The need to reduce greenhouse gas emissions.

　　由于日益严重的全球变暖趋向遭到世界各国的注重，温室气体减排越来越紧迫。发展可再生能源成为紧急任务。通过沼气提纯对完成我国节能减排目的具有重要意义。

　　Due to the increasingly serious trend of global warming, it is more and more urgent to reduce greenhouse gas emissions. Developing renewable energy has become an urgent task. The purification of biogas is of great significance for energy conservation and emission reduction in China.
