环戊烷水合物生长过程实验研究

Experimental Study on the Formation Process of Cyclopentane Hydrate

实验研究了环戊烷水合物形成过程,实验结果表明水合物相变过程包含降温、晶核诱导、水合物快速生长和水合物缓慢生长几个过程,其中晶核形成诱导期和生长期呈现出随机性的特点。水合物的形成首先出现水-环戊烷的的界面处,并向下生长。在水合物形成的最后阶段,水合物沿着铜管爬升生长,充满整个蓄冷器。

The formation process of cyclopetane hydrate is investigated experimentally. The process of hydrate phase change includes temperature drop, crystal nucleus inducement, hydrate growing quickly and hydrate growing slowly. Crystal nucleus inducement and hydrate growing show its randomness characteristics. Hydrate appears the interface of water and cyclopentane firstly, and grows downward. Hydrate climbs and grows alone copper tube at last and is full of the cold regenerator.
