Progress of rapid formation of gas hydrate by mechanical disturbance
摘要
Abstract
There is a vast application prospect about gas hydrate technology in solid natural gas storage and transportation,carbon dioxide capture and storage,and other areas. High efficiency and rapid formation of gas hydrate is the key of application technology industrialization. The formation mechanism of gas hydrate is introduced from the view of nucleation mechanism,phase equilibrium, and heat and mass transfer. The basic principles and characteristics of the common methods for rapid formation of gas hydrate by mechanical disturbance are introduced,including stir,spray and bubble. Moreover,on the basis of the new progress in the field of heat and mass transfer,the basic principles and characteristics of the new methods are described. The progresses of the methods including fluidized bed,ultrasonic,high gravity and impinging stream are mainly reviewed. The advantages and disadvantages of different methods of mechanical disturbances are analyzed and evaluated from the view of the rate of gas consumption,the formation rate of hydrate,total energy consumption and rate of gas conversion. Overall,various technologies for rapid formation of gas hydrate by mechanical disturbance are still in the laboratory stage. The formation rate of traditional technologies including stir,spray and bubble is low. The new technologies including fluidized bed,ultrasonic,high gravity and impinging stream also have various shortcomings,and needs further optimization and improvement. At last,all problems including exploring the microscopic nucleation mechanism,developing a new gas hydrate formation system with easy separation of solid and liquid,and constructing comprehensive evaluation system for gas hydrate reactor need to be solved further in the future research of gas hydrate formation.关键词
