蒙脱石对低浓度瓦斯水合分离效率的影响
Effect of montmorillonite on low-concentration mine gas hydration separation
摘要
Abstract
This paper aims to explore the method of improving the separation rate of hydrate by investigating the effect of montmorillonite（MMT） on CH4 separation.The investigation consists of studying the process of hydration curing using the two types of gas samples（A and B） with CH4 concentration of 24.9% and 40.4% and the system of（THF）-MMT,（SDS）-MMT and THF-SDS-MMT,and analyzing CH4 concentration in separation residues using gas chromatography.The results show that the use of MMT allows an increase in the hydrate separation efficiency,producing 3.02%,3.64% and 13.59% higher concentration of CH4 in sample A hydration phase than otherwise would occur,with the highest separation concentration of CH4 increasing up to 14.24%,while sample B is found to have 19.53%,14.48% and 22.41% higher concentration of CH4,with the highest separation concentration of CH4 increasing up to 30.36%.MMT addition,capable of improving the mole fraction of CH4 in the hydrate phase and increasing in the enrichment capability of CH4 in the hydrate,enables the separation and purification of low-concentration gas.关键词
