Description

technical field [0001] The present invention relates to a hydrate simulated synthesis and decomposition complete equipment system device, more specifically to a seabed natural gas hydrate simulated synthesis and decomposition complete equipment system device, and also relates to the seabed natural gas hydrate simulated synthesis and decomposition complete equipment A reactor in a system device belongs to the field of mechanical engineering. Background technique [0002] Natural gas hydrate is a strategic and environmentally friendly energy with huge reserves after coal and oil. It is known as the crown of new energy in the 21st century. This shows that governments and scientific and technological experts of various countries attach importance to it. Although the survey and research on gas hydrate in my country started relatively late, the research on marine gas hydrate conducted by the China Geological Survey has made remarkable progress in recent years. Gas hydrate simulat...

AI Technical Summary

Problems solved by technology

[0003] 1) Limited by the cost, manufacturing process, etc., the volume is too small, so it is difficult to apply in the research of gas storage capacity and thermal stability of natural gas hydrate;

[0004] 2) It is impossible to simulate the formation and decomposition of natural gas hydrate in real seabed sediment, so it cannot play a guiding role in the storage and exploration of seabed natural gas hydrate;

[0005] 3) Due to the use of naked eye observation when judging the formation / decomposition of hydrates, the judgment of the critical point of the reaction is uncertain, and at the same time, it is impossible to carry out simultaneous research and analysis of the binding reaction parameters after the experiment on the image;

[0006] 4) Insufficient real-time monitoring means, lack of support for the repeatability of simulation results, determination and verification of reaction conditions;

[0007] 5) The reactor cannot be quickly opened, and the synthesized hydrate cannot be quickly taken out for combustion, analysis or further research;

[0008] 6) Lack of real-time data and image analysis software support, limited experimental operation and analysis of experimental results
