Research system for utilizing CO2 gas to displace methane hydrate

Abstract

The invention relates to a research system for utilizing CO2 gas to displace methane hydrate, comprising a high-pressure reaction kettle, a gas supply system, a temperature control system, a gas-phase component detection system and a data acquisition system; the side wall of the reaction kettle is provided with two pieces of symmetrical pressure-resistant optical glass in which a window is provided with a visualization function; the reaction kettle is wrapped by a cooling water jacket which controls the constant temperature by the temperature control system; an inlet of the high-pressure reaction kettle is externally connected with a gas inlet system; a gas collecting port is connected with the gas-phase component detection system; and a temperature sensor and a pressure sensor on the high-pressure reaction kettle are externally connected with a data acquisition system. The research system has pressure resistance and convenient operation and is convenient to monitor; a magnetic coupling stirring system adopted not only solves the problem that sealability of high-pressure rotation is poor, but also has reliable operation and no noise; and the design of the visualized structure is convenient for observing experimental phenomenon in real time.

Description

Technical field [0001] The invention relates to a research device for the preparation and replacement of gas hydrates, in particular to a method for utilizing CO 2 Research system for gas replacement of methane hydrate. Background technique [0002] The use of hydrates to deal with greenhouse gases such as carbon dioxide is currently one of the hotspots in the international hydrate community. The carbon dioxide gas emitted by the combustion of the power plant is injected into the seabed under certain conditions and made into a gas hydrate state for isolation. Because carbon dioxide hydrate is denser than sea water, it can be permanently stored on the seabed, and this method has a great impact on the marine ecological environment. small. [0003] On the other hand, with the gradual decrease in the supply of traditional energy, the demand for non-traditional energy is increasing, and the natural gas in hydrate will become an important and clean potential energy. It has been found t...
