生物天然氣在國內(nèi)已發(fā)展十多年，但為何一直“叫好不叫座”，那么沼氣生物脫硫發(fā)展還存在哪些問題待解決？其實這與原料供應、技術(shù)裝備、運行管理等一系列環(huán)節(jié)都不無關系。
Biological natural gas has been developing for more than ten years in China, but why has it always been so popular? What problems still exist in the development of biogas desulfurization? In fact, it has nothing to do with a series of links, such as raw material supply, technical equipment, operation and management.
首要難題就是原料收儲運困難。生物天然氣原料分布分散，收儲運面臨較大挑戰(zhàn)。要實現(xiàn)規(guī)模效益，必須依靠大農(nóng)場及團隊。
The first difficulty is the difficulty of material storage and transportation. Biological natural gas (BNG) raw materials are dispersed, and its storage and transportation are facing great challenges. To achieve scale efficiency, we must rely on large farms and professional teams.
除此之外，生物天然氣配套設施包括了原料的收儲運、預處理、發(fā)酵轉(zhuǎn)化、凈化提純、燃氣及肥料輸運等環(huán)節(jié)，相關的國產(chǎn)、進口配套設備都較齊全，但仍然存在匹配性的問題。
In addition, the supporting facilities of bio-natural gas include the storage and transportation of raw materials, pretreatment, fermentation and transformation, purification and purification, gas and fertilizer transportation, and the related domestic and imported supporting equipment are relatively complete, but there are still matching problems.
在工程建設初期運行效果較好，隨著工程運行時間的延長，部分工程會出現(xiàn)運行效率降低甚至停滯、設施設備銹蝕、管道堵塞、罐體淤泥多、浮渣難處理等問題。
In the initial stage of construction, the operation effect is better. With the extension of the operation time, some projects will have problems such as lower or even stagnant operation efficiency, corrosion of facilities and equipment, blockage of pipelines, more silt in tanks, and difficult treatment of scum.
由于生物燃氣轉(zhuǎn)化成本高，設備運行條件惡劣，日常運行維護管理經(jīng)費沒有保障，造成出現(xiàn)故障后不能及時得到正常的維修，使得整個產(chǎn)業(yè)再次陷入困境。“生物天然氣‘三分建設，七分管理’，當前需要加強的就是項目實施完成后的運行與管理。同時，在項目規(guī)劃初期既要考慮建設投資，也要配備運行管理費用。
Due to the high cost of biogas conversion, the poor operating conditions of equipment and the lack of guarantees for daily operation and maintenance management expenses, the whole industry is once again in a dilemma because of the failure of biogas conversion, which results in the failure of normal maintenance in time. "Biogas's three-part construction and seven-part management" needs to be strengthened after the completion of the project operation and management. At the same time, in the initial stage of project planning, we should consider both construction investment and operation and management costs.
目前，我國的生物天然氣產(chǎn)業(yè)還處在發(fā)展初期，在提高工程規(guī)模化水平和效率，實現(xiàn)氣、液、固等產(chǎn)品的高值、高效綜合利用，提高工程的環(huán)保、生態(tài)、經(jīng)濟和社會效益上都應該多下功夫。要把影響工程商業(yè)運行的原料收集難、原料成本高、產(chǎn)品價格低、扶持政策不到位等問題予以解決。
At present, China's bio-natural gas industry is still in its early stage of development. More efforts should be made to improve the scale and efficiency of the project, realize high-value and efficient comprehensive utilization of gas, liquid and solid products, and improve the environmental protection, ecological, economic and social benefits of the project. The problems affecting the commercial operation of the project, such as difficult collection of raw materials, high cost of raw materials, low price of products and inadequate support policies, should be solved.
不僅如此，生物天然氣產(chǎn)業(yè)的上游原料供應和下游產(chǎn)品方面都缺乏專門的標準和技術(shù)規(guī)范，只能使用少數(shù)燃氣產(chǎn)業(yè)現(xiàn)有的標準規(guī)范。為此，馬隆龍建議，加快生物天然氣進入車用燃氣、工業(yè)用氣、城市燃氣管網(wǎng)、合同能源管理等多種清潔燃氣利用領域的標準體系，從生產(chǎn)與凈化、儲存、輸配、應用等環(huán)節(jié)進行標準制定，建立與現(xiàn)有長輸管道天然氣、城鎮(zhèn)燃氣標準體系相協(xié)調(diào)的通用和專用標準。
Moreover, there are no special standards and technical specifications for the upstream raw material supply and downstream products of the biogas industry, and only a few existing standards and specifications for the gas industry can be used. For this reason, Malonglong suggested that the standard system of bio-natural gas should be accelerated to enter the fields of vehicle gas, industrial gas, urban gas pipeline network, contract energy management and other clean gas utilization. Standards should be formulated from the aspects of production and purification, storage, transmission and distribution, application, and a general and special standard should be established to coordinate with the existing standard system of long-distance pipeline natural gas and urban gas.
