近年來,呈現(xiàn)了較多高產(chǎn)量沼氣工程,遠(yuǎn)遠(yuǎn)大于企業(yè)自用所需的氣量,多余沼氣常常通入鍋爐不完整熄滅以至直接排放,形成環(huán)境污染和資源糜費。在當(dāng)前節(jié)能減排嚴(yán)峻趨向下,沼氣提純生物天然氣是必然的開展趨向。
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.契合國度產(chǎn)業(yè)政策,是開展可再生能源、改善能源構(gòu)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,我國已成為第二大能源消費國,化石燃料的消費和運用惹起嚴(yán)重的溫室效應(yīng)、酸雨、毀壞臭氧層等環(huán)境問題。《國民經(jīng)濟和社會開展第十二個五年規(guī)劃綱要》提出,推進能源消費構(gòu)造和應(yīng)用方式革新,推進能源多元清潔開展。繼《天然氣應(yīng)用政策》施行后,相關(guān)部門出臺了《關(guān)于開展天然氣散布式能源的指導(dǎo)意見》等一系列政策,標(biāo)明了政府開展“氣體能源”,鼎力推進節(jié)能減排和積極開展低碳經(jīng)濟的決計和意志。生物天然氣作為一種清潔的氣體能源,以其循環(huán)環(huán)保、變“廢”為“寶”、副產(chǎn)品可應(yīng)用、本錢低廉、技術(shù)成熟易推行等特性,在補充我國氣體能源缺乏方面大有作為。
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.延長產(chǎn)業(yè)鏈,提升附加值,進步企業(yè)競爭力
2. Extend the industrial chain, enhance added value and improve the competitiveness of enterprises
由于世界經(jīng)濟增速放緩、國內(nèi)外產(chǎn)品市場低迷、市場競爭不時加劇,加之受政策調(diào)整、補貼規(guī)范降落等要素,企業(yè)利潤空間遭到擠壓。經(jīng)過提純制取生物天然氣,能夠延長公司產(chǎn)品產(chǎn)業(yè)鏈,提升產(chǎn)品附加值,是企業(yè)提升競爭力的有效手腕之一。
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.減少溫室氣體排放的需求
3. Demand for reducing greenhouse gas emissions
由于日益嚴(yán)重的全球變暖趨向遭到世界各國的注重,溫室氣體減排越來越緊迫。2007年在印尼巴厘島召開的結(jié)合國氣候變化大會和2009年的G20峰會都把減少化石能源耗費、開展可再生能源作為首要任務(wù)。CH4的溫室氣體效應(yīng)可達CO2氣體的21倍,全球溫室氣體效應(yīng)20%來自甲烷。假如沼氣得不到有效應(yīng)用,就會成為形成溫室效應(yīng)的元兇。以每日應(yīng)用沼氣提純制取6萬規(guī)范立方米生物天然氣為例,每年減排溫室氣體排放量相當(dāng)于約45.8萬tCO2,可見沼氣提純對完成我國節(jié)能減排目的具有重要意義。
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.
