Abstract

The invention relates to a low temperature high pressure gas hydrate replacement reaction kettle and a system used for replacement reaction of gas hydrate. The whole reaction kettle is soaked in a constant low temperature water bath to keep the low temperature, and a vacuum system performs vacuum pump in the low temperature high pressure reaction kettle through a gas inlet, a gas phase component detection system performs gas collection and analysis through a gas collection opening, a pressure control system is connected with the gas inlet of the low temperature high pressure reaction kettle to ensure the pressure required by the low temperature high pressure reaction kettle, a data acquisition system is connected with a temperature detection opening and a pressure detection opening of the low temperature high pressure reaction kettle to acquire system data. In the invention, static sealing replaces dynamic sealing, thus solving the problem of poor performance of high pressure rotary sealing, and having the advantages of reliable running and no noise. The phenomenon occurring in the reaction kettle can also be observed by a visible window in real time, and the gas component alteration in the gas hydrate solid phase can be measured by a Raman spectrometer in real time.

Description

technical field [0001] The invention relates to the field of gas hydrate replacement, in particular to a low-temperature and high-pressure gas hydrate replacement reactor. Background technique [0002] Human society in the 21st century is not only facing energy problems, but also shoulders the huge pressure of environmental protection, among which the problem of greenhouse effect is particularly prominent. As the most important greenhouse gas, carbon dioxide emission reduction, capture and sequestration have become the focus of attention of all countries. On February 16, 2005, the "Kyoto Protocol" came into effect, marking the beginning of the global response to greenhouse gas emissions to the concrete implementation stage. Treatment of CO using hydrate technology 2 Greenhouse gases such as GHGs have become a research hotspot in the international hydrate field. 2 The gas is injected into the seabed, and gas hydrates are formed under high pressure conditions for isolation....
