从安全角度看,煤层气开采是为了提高煤矿井下安全,减少事故。从利用的角度看,是获得相当多的新能源;从环境保护的角度来看,有必要充分利用开采后的零排放,否则不仅会浪费资源,还会影响大气。然而,我国煤层气的利用率并不高。以2012年为例,煤层气产量为126.02亿立方米,开采率为41.72%,其中地下开采率为25.73亿立方米,开采率为78.4%,地下开采率为100.3亿立方米,开采率为32.3%。

  From the safety point of view, coalbed methane mining is to improve the safety of coal mines and reduce accidents. From the perspective of utilization, it is necessary to obtain quite a lot of new energy; from the perspective of environmental protection, it is necessary to make full use of the zero emission after mining, otherwise it will not only waste resources, but also affect the atmosphere. However, the utilization rate of coalbed methane in China is not high. Taking 2012 as an example, the output of coalbed methane is 12.602 billion cubic meters, with a mining rate of 41.72%. Among them, the underground mining rate is 2.573 billion cubic meters, with a mining rate of 78.4%, and the underground mining rate is 10.03 billion cubic meters, with a mining rate of 32.3%.

  显然,提高煤层气的利用率,关键在于地下开采与利用技术。

  Obviously, the key to improve the utilization rate of coalbed methane is the underground mining and utilization technology.

  因此,低浓度气体浓度净化技术、大功率高参数内燃机直接发电、变压吸附净化技术等应运而生。

 Therefore, low concentration gas purification technology, high power and high parameter internal combustion engine direct power generation, PSA purification technology and so on came into being。

  低浓度氧气分离甲烷生产CNG(压缩天然气)和LNG(液化天然气)技术和工业示范,主要用于提取氧气的气体,通过变压吸附技术结合爆炸抑制技术,实现低浓度气体净化,氧含量低于0。5%,完全满足压缩天然气的质量要求。

  The technology and industrial demonstration of CNG (compressed natural gas) and LNG (liquefied natural gas) production by separating methane with low concentration oxygen are mainly used to extract oxygen gas. Through pressure swing adsorption technology combined with explosion suppression technology, the purification of low concentration gas is realized. The oxygen content is less than 0.5%, fully meeting the quality requirements of compressed natural gas.

  产生的压缩天然气每标准平方消耗约1千瓦时。通过该工艺,将瓦斯浓度由5%净化至95%,压缩至20 mpa以上的合格CNG,每立方米电耗1.7 KWH,循环水消耗0.2立方米。如果甲烷是分为液化天然气生产成本每立方米(包括正常操作的水和电力消耗,设备折旧、运营管理费用,维护成本)是1.4 - -1.6元,气体源成本是0.4元,总成本大约是2元,和工厂批发价格可以达到4元,意义2元的利润。例如,该公司在重庆的项目总投资为2.5亿元人民币,预计将在三年内收回成本。用可回收的非常规天然气补充清洁能源,可以缓解当地对清洁能源的需求,创造当地就业机会,并提供税收收入。如果国家对含氧天然气非常规天然气装置的生产给予天然气和天然气发电同样的激励,经济效益会更好,对行业的发展会起到积极的作用。

  The compressed natural gas produced consumes about 1 kwh per standard square meter. Through this process, the gas concentration is purified from 5% to 95%, compressed to a qualified CNG of more than 20 MPa, the power consumption per cubic meter is 1.7 kwh, and the circulating water consumption is 0.2 cubic meter. If methane is divided into LNG production cost per cubic meter (including normal operation water and power consumption, equipment depreciation, operation and management costs, maintenance costs), it is 1.4-1.6 yuan, gas source cost is 0.4 yuan, total cost is about 2 yuan, and the factory wholesale price can reach 4 yuan, meaning 2 yuan of profit. For example, the company's total investment in Chongqing is 250 million yuan, and it is expected to recover costs within three years. Supplementing clean energy with recoverable unconventional natural gas can alleviate local demand for clean energy, create local employment opportunities and provide tax revenue. If the state gives the same incentives to the production of unconventional natural gas plants with oxygen, the economic benefits will be better and the development of the industry will play a positive role.

  天然气发电仍然存在瓶颈。如果煤矿内的小瓦斯量不够,发电就不经济;然而,煤矿大气量大,需要将煤矿运出矿区。此外,电网的协调也不是很顺畅。天然气发电也有季节性因素,夏季满负荷,冬季不足。

  There are still bottlenecks in natural gas power generation. If the small amount of gas in the coal mine is not enough, power generation will be uneconomical; however, due to the large amount of air in the coal mine, the coal mine needs to be transported out of the mining area. In addition, the grid coordination is not very smooth. Natural gas power generation also has seasonal factors, full load in summer and insufficient in winter.
