化学添加剂对水合物生成和储气的影响
Influence of chemical additives on hydrate formation and gas storage
摘要
Abstract
In order to study effects of promoters on hydrate formation ,adopting a self-de-signed hydrate reaction system ,influences of the tetrahydrofuran (T HF ) and sodium dodecyl sulfate (SDS) on carbon dioxide hydrate formation were studied through experiments with con-stant temperature and volume .Hydrate formation rate ,gas storage capacity and the apparent hy-dration number were calculated on the basis of real-time measurements of system temperature and pressure in the process of hydrate formation .The result showed that the suitable concentra-tion of SDS can promote the dissolution of gas in the liquid phase ,and improve the grow th rate and gas storage density of hydrate . T HF only had little effect on hydrate generation process . Compound additives SDS and THF working together could promote the hydrate formation impor-tantly .关键词
