介绍了我国低浓度煤层气的利用现状,对当前几种浓缩技术进行了对比和分析,认为水合物浓缩低浓度煤层气法具有更广阔的前景。介绍了水合物基本理论,包括其晶体结构、相平衡热力学及生成动力学,阐述了通过强化气体水合物生成来浓缩低浓度煤层气的研究进展,并对水合物法浓缩低浓度煤层气技术进行了总结和展望。
The progress of utilization of low-concentration coal-bed methane is introduced. Several kinds of the current condensation technologies are compared and analyzed. The results show that the hydrate condensation of low concentration coal-bed methane has more broad prospects. Subsequently, the basic theories of hydrate, including crystal structure, phase equilibrium thermodynamics and kinetics are introduced. The progress of condensation of low- concentration coal-bed methane through enhancing the gas hydrate formation is expounded. Finally, the technology of hydrate concentrating low-concentration coal-bed methane is summarized and prospected.
