外部扰动促进气体水合物生成方法的研究进展

Research progress on methods for promoting gas hydrate formation through external disturbances

从气体水合物的形成条件和生成机制出发,阐述了外部扰动(温度、压力、机械等)在其生成过程中的影响,并分析了各自的优缺点。分析结果表明,温度、压力扰动在一定程度上能明显缩短诱导时间,但其促进机理还在摸索阶段;传统的机械扰动技术较成熟但大多存在结构和能耗问题;新型外场强化能够明显加快晶核形成。为进一步寻找更佳水合物生成促进方法提供了依据。

Starting from the formation conditions and generation mechanism of gas hydrates,the influence of external disturbances(temperature,pressure,mechanical,etc.)on their formation process is elaborated,and their respective advantages and disadvantages are analyzed.After analysis,it is found that temperature and pressure disturbances can significantly shorten the induction time to a certain extent,but their promotion mechanism is still in the exploratory stage.Traditional mechanical disturbance techniques are relatively mature,but most of them have structural and energy consumption issues.The new type of external field strengthening can significantly accelerate the formation of crystal nuclei.This provides a basis for further searching for better methods to promote hydrate formation.
