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. In order to understand the formation characteristics of C3H8 hydrate and accelerate the formation process of C3H8 hydrate, a series of experiments were carried out on pure water, sodium dodecyl sulfate (SDS, concentration of 1950 × 10-6) and dodecylbenzenesulfonic acid The induction time and the formation rate of C3H8 hydrate in sodium (SDBS) (concentration 400 × 10-6) were studied.The results showed that the induction time of C3H8 hydrate in pure water system was the longest in the temperature range of 0.8 ~ 1.2 ℃, The formation rate of C3H8 hydrate was the fastest, reaching 0.0224 mm / h. Compared with the pure water system, the surfactant significantly shortened the induction time of C3H8 hydrate and increased the formation rate of C3H8 hydrate.
