【Abstract】 A new method was presented for mine gas separation based on hydration mechanism.Twelve reaction systems composed of four types of gas sample and three types of reagent were experimented on using self-developed visual experimental apparatus to investigate the following contents: ① variation rule of thermodynamic parameters in mine gas separation process based on hydration technology;② the separation and purification concentration of CH4.The following results were obtained: thermodynamic parameters of four kinds of different ratio gas sample in separation process and the chromatographic analysis results of gas components in the separation container before and after separation of three reaction systems.Major findings from the experiments are as follows: ① for type-I gas sample with concentration of 57.899% and type-IV gas sample with CH4 concentration of 34.130%,after the first separation stage,the purification concentration of CH4 can attain to 77.217%~88.133% and 66.385%,respectively;② THF has a notable effect on improving the thermodynamic conditions of gas hydration and the separation efficiency.更多还原
