I. Overview
1. The natural gas hydrate density testing system is used to simulate hydrates formed under various conditions, and the pressure drop method is used to measure the density of various hydrates and conduct kinetic studies.
2. The density testing and kinetic studies of natural gas hydrates require precise measurement of pressure, temperature, and volume data. The system should include a low-temperature thermostat bath (ethylene glycol aqueous solution), a natural gas constant pressure control module, a natural gas hydrate volume measurement module, a natural gas hydrate synthesis reactor swing system, a vacuum module, and a data acquisition system.
3. The applicable media for the equipment are seawater, marine sediments, natural gas hydrates, etc.
4. The equipment adopts a modular design, which is not only convenient for operation and maintenance, but also can increase the functions of the equipment through different combinations.
