Energy Calculation and Analysis on Laboratory Freezing Experiment of Freezing Sampler for Gas Hydrate

Abstract:

According to freezing sampling method of gas hydrate with dry ice as refrigerant and alcohol as cooling agent, calculation was given for dry ice and alcohol consumption, and the consumption of dry ice and alcohol with the double-layer insulation were calculated out. The feasibility of the calculation method was verified through experiments and computer simulations. Considering the problems in the experiment, some improvement was suggested to the experimental device to provide a reference to sampler design.
