摘要

煤层气（CBM）分离提纯对保障矿井安全生产、实现双碳目标等具有重要意义。基于水合物法分离技术，在十二烷基硫酸钠（SDS）、油水乳液和纯水体系中施加4种驱动压力（1 MPa、2 MPa、3 MPa和4 MPa），开展了高浓度煤层气（甲烷体积分数60%）水合分离实验。结果表明，3种体系中煤层气水合物的生长速率均随驱动压力的增大而持续增大，添加SDS和油水乳液能进一步增大水合物生长速率。不同驱动压力下，煤层气经纯水体系、SDS体系和油水体系分离后，甲烷回收率分别为10.02%~11.75%、31.00%~43.36%和21.68%~24.36%，其中SDS体系较纯水体系甲烷回收率增大了3~4倍，油水体系则增大了约2倍。3种体系中甲烷回收率均随驱动压力增大而增大，但驱动压力为3~4 MPa时，SDS和油水乳液体系的分离因子呈下降趋势，分离难度变大，可见3 MPa为最佳驱动压力，此时煤层气经SDS和油水乳液体系提纯后，甲烷体积分数分别达到81.13%和82.32%。

Abstract

The separation and purification of coalbed methane (CBM) are crucial for ensuring safe production in mines and achieving carbon neutrality goals. Using hydrate separation technology

experiments were conducted to separate high-concentration CBM (with methane volume fraction of 60%) in sodium dodecyl sulfate (SDS)

oil-water emulsion and pure water systems under four different driving pressures (1 MPa

2 MPa

3 MPa and 4 MPa). The results indicate that the growth rate of CBM hydrate increases continuously with the driving pressure in all three systems. The addition of SDS and oil-water emulsion further increases the hydrate growth rate. Under different driving pressures

the methane recovery rates after separation in pure water

SDS and oil-water systems are 10.02% to 11.75%

31.00% to 43.36% and 21.68% to 24.36%

respectively. Compared to the pure water system

the methane recovery rate is 3 to 4 times higher in the SDS system and approximately 2 times higher in the oil-water emulsion system. The methane recovery rate increase with the driving pressure in all three systems. However

the separation factors of SDS and oil-water emulsion systems decrease at driving pressures of 3 to 4 MPa

indicating increased separation difficulty. Therefore

3 MPa is identified as the optimal driving pressure. At this pressure

the methane volume fraction after purification in the SDS and oil-water emulsion systems reach 81.13% and 82.32%

respectively.
