The reaction process and the reaction kinetics of forming a hydrate from natural gas and ice are studied on a small sized industrial unit. The experimental results show that the formation conditions of the hydrate are independent on induction time. It is also found that the greater degrees of supersaturation and supercooling are favorable to the formation of the hydrate, and the effect of disturbance on the similar crystallization processes to the formation of hydrate is investigated by using superpressure. The optimal reaction time is obtained finally.
