GAS HYDRATE FORMATION BY WATER SPRAYING
An experimental study of gas hydrate formation has been performed using natural gas. The experiments were conducted in a water-spraying reactor. The initial pressure in the reactor was maintained at a desired level by supplying natural gas through a port at the top of the test cell. Water was continuously sprayed into the high-pressure reactor and drained from the bottom of the reactor and circulated back through the spray nozzle. The inter space of the test cell is cooled by the circulated water through an external cooling jacket. The process of hydrate formation was observed visually through a pair of glass windows in the reactor wall, as well as using a digital video camera to record it. The characteristic of gas hydrate formation by water spraying under different temperature and pressure conditions was discussed in this paper. It was found that the morphology of the hydrate formed by water spraying looks like ice-slurry, which depends on the initial pressure and temperature. At a certain reaction pressure, the rate of hydrate formation was determined increasing with lower temperature. And also, water spraying can shorten the induction time much effectively compared to a quiescent system.
