摘要
为了解C3H8水合物的生成特性，加快其生成过程，在可视化实验装置上分别研究了在纯水、十二烷基硫酸钠（SDS，浓度1950×10^-6）和十二烷基苯磺酸钠（SDBS，浓度400×10^-6）中c3H8水合物的诱导时间、生成速率等．结果表明，在0．8-1．2℃温度范围内，纯水体系中C3H8水合物的诱导时间最长，SDS体系中C3H8水合物的生成速率最快，达0．0224mm／h．与纯水体系相比，表面活性剂明显缩短了C3H8水合物的诱导时间，提高了其生成速率．
In order to understand the formation characteristics of C3H8 gas hydrate and accelerate the formation process, the formation experiments of C3H8 are carried out with a visualization installation in the systems of pure water, 1950×10^-6（ω） SDS and 400×10^-6（ω） SDBS, respectively. And the induction time and formation rate of C3H8 in three different systems examined. The results show that in the temperature range between 0.8 and 1.2 ℃, the induction time of propane hydrate is the longest in pure water among three different systems, and the average formation rate is fastest in 1950×10^-6（ω） SDS, up to 0.0224 mm/h. Compared with the system of pure water, surfactant can shorten the induction time of C3Hs hydrate formation process and enhance its formation rate.
