Abstract
Gas hydrate slurry formation systems are provided. The gas hydrate slurry formation system includes a cavitation chamber configured to receive a fluid and a cavitation device placed within the cavitation chamber. The cavitation device is configured to form a plurality of bubbles within the fluid in the cavitation chamber. The gas hydrate slurry formation system also includes a gas inlet configured to introduce a gas within the cavitation chamber such that the gas is entrained in the plurality of bubbles to form a plurality of gas-entrained bubbles. The plurality of gas-entrained bubbles implode within the cavitation chamber to form a gas hydrate slurry.
Claims12
A method of forming a gas hydrate slurry, the method comprising:
- introducing a fluid within a cavitation chamber;
- introducing one or more thermodynamic and kinetic promoters within the cavitation chamber to facilitate formation of the gas hydrate slurry, wherein the one or more thermodynamic and kinetic promoters include at least one member selected from the group consisting of tetra-n-butylammonium bromide (TBAB), tetra-n-butylammonium chloride (TBAC), tetra-n-butylammonium fluoride (TBAF), tetrahydrofuran (THF), sodium dodecyl sulphate (SDS), and combinations thereof;
- forming a plurality of bubbles within the fluid in the cavitation chamber by a cavitation device, wherein forming the plurality of bubbles comprises forming the plurality of bubbles in-situ, by a hydrodynamic cavitation, an acoustic cavitation, or a combination thereof, wherein the hydrodynamic cavitation involves a turbine to reduce pressure of the fluid below a vapor pressure of the fluid to facilitate formation of the plurality of bubbles, wherein a rotation speed of the turbine ranges between 50 rpm to 1010 rpm;
- entraining a gas in the plurality of bubbles to form a plurality of gas-entrained bubbles;
- and
- converting the plurality of gas-entrained bubbles to the gas hydrate slurry.
