The whole set of the experiment device is convenient to operate and low in operation cost; the requirements of hydrate slurry generation and flowing principle experiments are met.

Description

technical field [0001] The invention belongs to the technical field of gas hydrate application and storage and transportation, and relates to an experimental device, more precisely, a pipeline type gas hydrate generation experimental device. Background technique [0002] Gas hydrates refer to light gases such as: methane, ethane, propane, CO 2 、H 2 Non-stoichiometric solid crystalline substances generated by S, etc. and water at a certain temperature and pressure (generally low temperature and high pressure). With the deepening of gas hydrate research, especially the development of research on the promotion of gas hydrate formation, the application prospects of gas hydrate technology in natural gas storage and transportation, and mixed gas separation are increasingly emerging. However, the application of hydrates in these fields is closely related to the promotion of gas hydrates. Hindered by factors such as low gas storage density, slow formation rate, and long induction...

Problems solved by technology

Nowadays, how to carry out the technological design of the hydrate slurry transportation pipeline is still in the frontier research field in the world, and the research on the flow law of the hydrate slurry is the basis of the technological design of the transportation pipeline. At present, only a few scholars have carried out some quantitative experiments. However, due to the differences in the experimental equipment, media and conditions used, there is no consensus in theory, and there are fewer literatures on the two-phase flow of gas hydrate slurry, so the research work in this area needs to be deepened urgently
