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0.0224 mm/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.

Abstract: 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(w) SDS and 400′10-6(w) 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(w) SDS, up to 0.0224 mm/h. Compared with the system of pure water, surfactant can shorten the induction time of C3H8 hydrate formation process and enhance its formation rate.
