摘要
为探究温度对瓦斯水合物快速合成的影响,利用自主搭建的可视化瓦斯水合分离强化实验装置,针对不同初始温度的高浓度瓦斯混合气体开展TBAB和SDS协同作用下的瓦斯水合分离动力学研究。结果表明,瓦斯水合物合成由快速合成、缓慢合成、稳定阶段构成。2℃时水合速率、平均气体消耗量最高,分别达到0.056mol/min和0.668mol,最有利于加快水合物合成。随着温度升高,平均气体消耗量和水合生长速率均在5℃达到最低。TBAB-SDS协同作用对瓦斯水合物生长起促进作用,然而TBAB自身合成水合物时存在较大相变潜热,在一定程度上会抑制SDS对瓦斯水合物合成的促进作用。
This paper is focused on investigating the effect of temperature on gas hydrate rapid growth. The investigation entails using visual gas hydration separation and strengthening experimental device for an experimental study on gas hydrate separation kinetics for high concentration gas mixture under synergistic action of TBAB and SDS at different initial temperatures. The results show that the gas hydrate formation consists of the three stages, rapid, slow and stable one;the hydration rate and the average gas consumption at 2 ℃ is up to the peak value of 0.056 mol/min and 0.668 mol respectively, which is most favorable to the faster hydrate formation;along with the increase of temperature comes the lowest value in the average gas consumption and hydration growth rate at 5 ℃;and the synergism of TBAB-SDS could promote the growth of gas hydrate while a large latent heat of phase change during the formation of TBAB gas hydrate tends to inhibit the promoting effect of SDS on the formation of gas hydrate.
