Simulation of Sulfur Dioxide and Ethane Hydrate Systems at Different Temperatures
Molecular dynamics simulations were used to study the variation of sulfur dioxide and ethane hydrate systems at different temperatures of 275,285,295 and 305 K under the pressure condition of 10 MPa.The diffusion coefficients of sul-fur dioxide,ethane,and water were predicted,and structural properties such as density,hydrogen bonding number,and co-ordination number were explored.The results showed that water was more influenced by temperature,and sulfur dioxide was more easily combined with water,while ethane was crowded out by water and sulfur dioxide and accumulates in large quantities to achieve the purpose of collecting and displacing ethane.
