天然气水合物诱导时间影响因素的试验研究

以气体水合物形成过程中的诱导现象为基础,通过对喷雾强化方式制取天然气水合物的诱导时间进行试验研究,考察分析了系统进气方式、温度、压力、水源及喷嘴等因素对诱导时间的影响规律.试验表明,喷雾方式制取天然气水合物时,诱导时间普遍较短,诱导现象不明显;反应釜设定初始温度和压力对诱导时间有一定影响,但不是很明显;水源和雾化喷嘴对诱导时间的影响较大.因此,喷雾强化方式可以大大缩短水合物形成的诱导时间,是一种行之有效的促进水合物形成的技术.

Experimental Study on Influential Factors of Induction Time of Natural Gas Hydrate

Based on the induction phenomenon caused in gas hydrate formation,the influential rules of its gas entrance mode,temperature,pressure,water resources and nozzle on the induction time are analyzed by means of experimental study on the induction time of gas hydrate formation obtained by water spray and enhancement.Experiment shows that when the gas hydrate is obtained by spray,its induction time is generally shorter,its phenomenon is not obvious,setting of initial temperature and pressure with an autoclave has certain influence on induction time,but not obvious,water resources and spray nozzle have bigger influence on the induction time.Therefore the mode of spray and enhancement can greatly reduce the induction time of forming the hydrate,it is an effective technique for promoting the hydrate.
