近年来,呈现了较多高产量沼气工程,远远大于企业自用所需的气量,多余沼气常常通入锅炉不完整熄灭以至直接排放,形成环境污染和资源糜费。在当前节能减排严峻趋向下,沼气提纯生物天然气是必然的开展趋向。
In recent years, there have been many high-yield biogas projects, which are far larger than the amount of gas needed for self-use. The excess biogas often goes into the boiler and is not completely extinguished or even directly discharged, resulting in environmental pollution and resource waste. At present, energy saving and emission reduction are getting worse, biogas purification is an inevitable trend.
1.契合国度产业政策,是开展可再生能源、改善能源构造的需求
1. It is the demand of developing renewable energy and improving energy structure that conforms to the national industrial policy.
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惹起严重的温室效应、酸雨、毁坏臭氧层等环境问题。《国民经济和社会开展第十二个五年规划纲要》提出,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。继《天然气应用政策》施行后,相关部门出台了《关于开展天然气散布式能源的指导意见》等一系列政策,标明了政府开展“气体能源”,鼎力推进节能减排和积极开展低碳经济的决计和意志。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、本钱低廉、技术成熟易推行等特性,在补充我国气体能源缺乏方面大有作为。
At present, China has become the second largest energy consumer. The consumption and use of fossil fuels cause serious environmental problems such as greenhouse effect, acid rain and ozone layer destruction. The Outline of the Twelfth Five-Year Plan for National Economic and Social Development put forward that we should promote the innovation of energy consumption structure and application mode, and promote energy diversification and clean development. Following the implementation of the Natural Gas Application Policy, the relevant departments issued a series of policies, such as the Guiding Opinions on the Development of Natural Gas Disseminated Energy, indicating the Chinese Government's determination and will to develop "Gas Energy", vigorously promote energy conservation and emission reduction, and actively develop a low-carbon economy. As a kind of clean gas energy, bio-natural gas, with its characteristics of recycling environmental protection, turning waste into treasure, by-products can be applied, low cost, mature technology and easy implementation, has made great achievements in supplementing the lack of gas energy in China.
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
由于世界经济增速放缓、国内外产品市场低迷、市场竞争不时加剧,加之受政策调整、补贴规范降落等要素,企业利润空间遭到挤压。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效手腕之一。
Due to the slowdown of world economic growth, the downturn of domestic and foreign product markets, the intensification of market competition from time to time, as well as the factors of policy adjustment and the fall of subsidies, the profit margin of enterprises has been squeezed. The purification of bio-natural gas can prolong the company's product industry chain and enhance the added value of products, which is one of the effective ways to enhance the competitiveness of enterprises.
3.减少温室气体排放的需求
3. Demand for reducing 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。2007年在印尼巴厘岛召开的结合国气候变化大会和2009年的G20峰会都把减少化石能源耗费、开展可再生能源作为首要任务。CH4的温室气体效应可达CO2气体的21倍,全球温室气体效应20%来自甲烷。假如沼气得不到有效应用,就会成为形成温室效应的元凶。以每日应用沼气提纯制取6万规范立方米生物天然气为例,每年减排温室气体排放量相当于约45.8万tCO2,可见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 trend of global warming has attracted worldwide attention, greenhouse gas emission reduction is becoming more and more urgent. Both the 2007 United Nations Climate Change Conference in Bali, Indonesia, and the 2009 G20 Summit have made reducing fossil energy consumption and developing renewable energy as their top priorities. The greenhouse gas effect of CH4 is 21 times that of CO2, and 20% of the global greenhouse gas effect comes from methane. If biogas is not effectively applied, it will become the main culprit of greenhouse effect. Taking the daily application of biogas purification to produce 60,000 cubic meters of biogas as an example, the annual emission reduction of greenhouse gases is equivalent to about 458,000 tCO2, which shows that biogas purification is of great significance to achieve the goal of energy saving and emission reduction in China.
