INVESTIGATION ON A NOVEL REACTOR FOR GAS HYDRATE PRODUCTION
Gas hydrates have a large capacity for the storage of gases and are an attractive method for gas filtration and transportation. However, hydrate formation is usually controlled by the rate of crystallization and thus it can be a slow process. A technology that will rapidly and continuously form hydr...
