Abstract: A temperature testing system for hydrate nucleation and phase transition based on infrared imaging is provided and includes a gas-liquid supplying device, a refrigeration device, an infrared imaging device, a hydrate generation device, and a data acquisition device. The gas-liquid supplying device is configured to provide a gas and a liquid required for synthetizing a hydrate. The refrigeration device is configured to provide a temperature environment required for synthetizing the hydrate. The infrared imaging device is configured to in-situ measure temperature changes caused during a formation of the hydrate. The hydrate generation device is configured to provide a visual growth environment for nucleation and phase transition of the hydrate. The data acquisition device is configured to collect a temperature, a system pressure, and infrared imaging data from the hydrate generation device. The temperature testing system can accurately determine the temperature evolution during the nucleation, formation, and decomposition of the hydrate.
