Visual gas hydrate experimental device

Abstract

The invention discloses a visual gas hydrate experimental device. The visual gas hydrate experimental device comprises a reactor, a constant-current gas supply system, a constant-current liquid supply system, a temperature control system, a constant-pressure gas exhaust system, a sampling analysis system and a data acquisition and processing system, wherein the reactor is divided into a plurality of sections; each section is provided with a window; a water jacket is arranged on an external wall without the window; a feeding hole is formed at the bottom; the constant-current gas supply system and the constant-current liquid supply system supply gas and a solution to the reactor respectively at a constant speed; the temperature control system controls the gas and the solution which are to be supplied to the reactor and controls a temperature of each water jacket; the constant-pressure gas exhaust system is used for exhausting the gas from the reactor and controlling a pressure in the reactor to be constant; the sampling analysis system takes samples from the interior of the reactor and carries out component analysis; and the data acquisition and processing system acquires the data of the constant-current gas supply system, the constant-current liquid supply system, the reactor and the temperature control system and carries out analysis. By adoption of the scheme, fast and efficient generation of a gas hydrate can be realized, on-line real-time observation of the crystal structure and the appearance of the hydrate in the process of hydrate composition / decomposition can be also realized, and the crystal structure and the appearance of the hydrate are analyzed by image processing software.

Description

technical field [0001] The invention relates to a gas hydrate experimental device, in particular to an experimental device which can be used for multi-component mixed gas hydrate formation / decomposition kinetics, hydrate crystal structure and morphology determination. Background technique [0002] Gas hydrate (hereinafter referred to as hydrate) is composed of water and CH 4 、C 2 h 6 , CO 2 or H 2 The non-stoichiometric clathrate crystalline substance formed by small molecule gases such as S under high pressure and low temperature environment is also called clathrate hydrate. The host water molecules are connected by hydrogen bonds to form some polyhedral cages, and guest molecules of appropriate size can be filled in these cages to make them thermodynamically stable. Gas hydrate has a strong gas storage capacity, and can store 160-180m3 per cubic meter 3 Gas, and solid, easy to transport. Gas hydrate technology has broad application prospects. In addition to natural ...
