CO2 hydrate formation and cold thermal energy transportation evaluation.

Summary

The reduction of greenhouse gases emission is vital for preventing global warming. Among the low global warming potential (GWP) refrigerants, CO2 hydrate slurry can be an appropriate solution that can be both environmentally friendly and an effective secondary refrigerant. CO2 hydrate is composed of water and carbon dioxide where CO2 is entrapped in the hydrogen bonded water cages. The formation conditions such as high pressure and low temperature make its direct application challenging as a secondary refrigerant in the actual industrial fields. Therefore, thermodynamic promoters must be present to ease the equilibrium conditions. Tetrahydrofuran (THF) allows the CO2 hydrate to be formed in a relatively lower pressure and higher temperature. The objective of this study is to analyze the THF+CO2 hydrate formation performance and cold thermal energy transportation application under the specified experimental conditions. The selected absorbents are applied in a refrigerating system to evaluate the thermal energy transportation performance during the hydrate dissociation process.
