Title:
APPARATUS AND METHOD FOR RAPID PREPARATION OF GAS HYDRATE COLUMN
Document Type and Number:
WIPO Patent Application WO/2021/208509
Kind Code:
A1
Abstract:
An apparatus and a method for rapid preparation of a gas hydrate column, comprising a high-pressure-resistant kettle, a pressure control apparatus, a liquid compensation apparatus, a liquid discharge apparatus, a temperature measurement and control apparatus, a liquid pressure control apparatus, and an electric heating apparatus. In a hydrate generation process, a piston at the top of the high-pressure-resistant kettle creates shocks in the pressure of a gas phase in the high-pressure-resistant kettle by means of small-amplitude reciprocating motion, thereby causing a dissolved gas to form a large amount of bubbles in a liquid phase, so as to increase the surface area of gas/liquid contact in the high-pressure-resistant kettle, and accelerating hydrate generation. After the solution in the high-pressure-resistant kettle is transformed into a solid-state hydrate, by means of the piston at the top of the high-pressure-resistant kettle compressing the resulting hydrate powder, a block-shaped hydrate is obtained. The present invention is able to provide a hydrate product having a regular geometric shape, and the apparatus features a simple structure, stable operation, and relatively low energy consumption.
