四丁基溴化铵水合物的生成-分解特性
Formation-dissociation characteristics of TBAB hydrate
摘要
Abstract
Based on die investigation of hydrate suspension multiphase transportation technology, experiments on TBAB hy-dtate formation-dissociation characteristics in invert emulsions formed by TBAB solution and diesel were carried out. The following results were obtained; The formation of TBAB hydrate in invert emulsions requires lower temperature and longer induction time compared with that in TBAB aqueous solutions. The apparent viscosity of TBAB hydrate suspension is higher than that of corresponding invert emulsion signifieantly at the same shear rate. The non-Newtonian phenomenon of TBAB hydrate suspension is more obvious and the apparent viscosity of TBAB hydrate suspension increases with the rise of TBAB hydrate particle volume fraction. When the temperature increases, TBAB hydrate dissociates rapidly in invert emulsions, transforming from solid particles to liquid. This phenomenon has obvious demulsificatkm effect as invert emulsions, which induces instability of the complex system containing TBAB hydrate suspension and water/diead e-riaion关键词
