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

1、符合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. Environmental and sustainable development policy is the demand for developing renewable energy and improving energy structure.

目前，我国已成为二大能源消费国，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 consumer. The consumption and application 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 development of diversified and clean energy. As a clean gas energy, biological natural gas has great potential in the utilization of new energy because of its characteristics of recycling and environmental protection, changing "waste" into "treasure", applicable by-products, mature technology and easy implementation.

2、延长产业链，提升附加值，进步企业竞争力。

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

能源公司竞争激烈，经过提纯制取生物天然气，能够延长公司产品产业链，提升产品附加值，是企业提升竞争力的有用手段之一。

Energy companies are highly competitive. The production of biological natural gas through purification can prolong the industrial chain of the company's products and enhance the added value of products. It is one of the useful means for enterprises to enhance their 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。

As the increasingly serious warming trend has attracted the attention of countries all over the world, greenhouse gas emission reduction is becoming more and more urgent. Developing renewable energy has become an urgent task. Biogas purification is of great significance to achieve the purpose of energy conservation and emission reduction in China.
