1. Overview
Gas hydrate is a cage-like ice crystal compound composed of different gases as carrier molecules filled into the cage space formed by the main water molecules at a specific temperature and pressure, also known as cage-like hydrate. Among them, natural gas hydrate is widely distributed in the soil layer of the permafrost zone or the deep seabed of the continental margin. With the world's energy consumption and the crisis, the research on the exploitation of natural gas hydrate is imminent. At the same time to solve the gas pipeline transportation in the formation of hydrate blocking pipeline, the use of hydrate method to solve the gas storage and transportation, air conditioning in the new efficient cold storage medium development and hydrate method separation of gas mixture technology are to be the gas hydrate system research.
In order to carry out the research on the synthesis, decomposition, thermodynamics and mining methods of gas hydrate, and to find a better use of the development of gas hydrate technology, the design and processing of the special hydrate dynamics experimental device is urgent.
