Progress in developing an innovative lean burn catalytic turbine technology for fugitive methane mitigation

Shi SU, Xinxiang YU

《能源前沿（英文）》 2011年第5卷第2期页码 229-235 doi: 10.1007/s11708-011-0147-9

摘要： Approximately 2.8 × 10 m of methane is emitted per year to the atmosphere from coal mining activities around the world. Mitigation and utilization of the fugitive coal mine methane is very difficult because its concentration is very low and varies from 0.1% to1%, and the methane is contained in a large air flow rate of 150–400 m /s. This paper overviews existing and developing technologies for the mitigation and utilization of the fugitive mine methane, and then presents research progress in developing an innovative lean burn catalytic turbine technology for fugitive methane mitigation and utilization. This turbine system can be powered with about 1% methane in air.

关键词： coal mine methane mitigation and utilization lean burn gas turbine catalytic combustion

《化学科学与工程前沿（英文）》 2011年第5卷第2期页码 139-161 doi: 10.1007/s11705-010-0527-4

摘要： This paper presents a summary review on mass transport of coal seam gas (CSG) in coal associated with the coalbed methane (CBM) and CO geo-sequestration enhanced CBM (CO -ECBM) recovery and current research advances in order to provide general knowledge and fundamental understanding of the CBM/ECBM processes for improved CBM recovery. It will discuss the major aspects of theory and technology for evaluation and development of CBM resources, including the gas storage and flow mechanism in CBM reservoirs in terms of their differences with conventional natural gas reservoirs, and their impact on CBM production behavior. The paper summarizes the evaluation procedure and methodologies used for CBM exploration and exploitation with some recommendations.

山西沁水煤层气压裂施工的横向效应

李梦溪,张聪

《中国工程科学》 2012年第14卷第4期页码 16-19

摘要：

介绍了在山西沁水盆地煤层气压裂时监测到的压裂施工的横向效应，监测使用微地震方法。发现沿人工裂缝法向方向的邻井在施工时出现气量减少、枯竭、出水等反应，沿人工裂缝走向方向的邻井反应滞后。这一发现使笔者注意到煤层气压裂施工的横向挤压作用可能即时影响邻井产量，压裂设计时应该注意到这一反应的不良影响。

Technology Development and Engineering Practice for Protection and Utilization of Water Resources in Coal

Da-zhao Gu

《工程管理前沿（英文）》 2016年第3卷第1期页码 59-66 doi: 10.15302/J-FEM-2016010

摘要： Shanxi, Shaanxi, Inner Mongolia, Ningxia, and Gansu (hereafter generally referred as “the Western Area”) are major coal-producing areas in China due to rich coal resources and good mining conditions. However, the Western Area has a serious water shortage. The surface evaporation is huge and a great amount of mine water generated in coal mining is evaporated and lost after discharging to surface. In order to protect and utilize the water resources during large-scale coal mining in the Western Area, Shenhua Group has put forward a technological idea to store mine water in underground mined areas and successfully researched and developed the coal mine underground reservoir technology by solving the technical difficulties of water source prediction, reservoir site selection, reservoir capacity design, dam construction, safety guarantee, water quality control and so on through 20 years of exploration. Now Shenhua Group has successfully established a batch of reservoir in the Shendong Mining Area, obtaining great economic and social benefits. The technology is also extended to other western mining areas, providing an effective path for harmonic mining of coal and water resources in western China.

Liquefaction and impurity separation of oxygen-bearing coal-bed methane

Qiuying LI, Yonglin JU, Li WANG,

《能源前沿（英文）》 2010年第4卷第3期页码 319-325 doi: 10.1007/s11708-010-0115-9

摘要： Coal-bed methane (CBM) is a type of clean energy. However, most oxygen-bearing CBM have not yet to be utilized due to limited techniques, and when utilized, the discharged gas leads to resource wastage and environment pollution. In this paper, a liquefaction process is proposed and designed for the specified oxygen-bearing CBM obtained from the Daqing Qingshen gas field. The distillation column is employed to separate the oxygen and nitrogen components present in the CBM. HYSYS software is adopted to simulate the process, and the results reveal that the energy consumption of the whole liquefaction process is low. Moreover, oxygen and nitrogen are nearly removed completely, achieving a high-purity liquefied natural gas product with a high methane recovery rate. The applicability and safety of the liquefaction process are also analyzed. The simulation results can offer references for the separation of the oxygen component from CBM.

《中国工程科学》 2001年第3卷第2期页码 39-46

摘要：

煤矿的生产和实践证明，发生在矿井中的动力现象具有分区和成带的特点。文章探讨了把煤、岩和瓦斯作为一个体系，采用力学方法的划分问题。根据对煤岩复合样及含瓦斯煤样在复杂应力状态下力学性质的分析，基于对Drucker-prager理论的修正和完善，建立了它们的断裂判据，并给出了计算稳定性系数和潜在弹性应变能密度的公式，提出了按这两个指标划分煤与瓦斯突出潜在危险区（带）的基本方法。

Dissolved methane in anaerobic effluent: Emission or recovery?

《环境科学与工程前沿（英文）》 2022年第16卷第4期 doi: 10.1007/s11783-022-1537-4

摘要： Various anaerobic processes have been explored for the energy-efficient treatment of municipal wastewater. However, dissolved methane in anaerobic effluent appears to be a barrier towards the energy and carbon neutrality of wastewater treatment. Although several dissolved methane recovery methods have been developed, their engineering feasibility and economic viability have not yet been assessed in a holistic manner. In this perspective, we thus intend to offer additional insights into the cost-benefit of dissolved methane recovery against its emission.
