Abstract

The invention provides a self-suction dynamic visualization experiment device for determining hydrate phase equilibrium conditions. The experiment device comprises a reaction kettle with an observation window arranged at a constant-temperature water bath, the reaction kettle is connected with a gas cylinder group, a vacuum pump, a temperature sensor and a pressure sensor; the temperature sensor and the pressure sensor are connected to a data acquisition monitoring system; the reaction kettle is a high-pressure reaction kettle of which the pressure in the kettle is adjusted by a vacuum pump anda gas cylinder and the temperature in the kettle is adjusted by the constant-temperature water bath; when an experiment is carried out, the hydration state of a substance in the kettle can be observed at the observation window, and the data acquisition monitoring system records temperature data and pressure data corresponding to different hydration states of the substance in the kettle; the phaseequilibrium condition of the hydrate can be visually and conveniently tested.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a self-priming dynamic visualization experimental device for measuring hydrate phase equilibrium conditions. Background technique [0002] Gas hydrate is a solid cage crystal similar to ice formed by gas molecules and water at a certain temperature and pressure. The gas molecules generally include methane, carbon dioxide or other hydrocarbons. The 21st century is facing a huge energy problem. Gas hydrate, as an unconventional energy source, has attracted the attention of scientists all over the world because of its environmental protection and huge reserves. [0003] Taking natural gas hydrate as an example, when natural gas and water or solution are fully contacted under certain conditions, gas hydrates that can store a certain amount of natural gas can be formed, and the advantages of high gas storage density of natural gas hydrates can be used to make gas hydrat...
