Abstract

The objective of this work is the investigation of tetrahydrofuran hydrate formation under atmospheric pressure in a static reactor without stirring. The growth rate of hydrate is mostly controlled by the conduction heat transfer phenomenon. An approximate method based on the improved quasi solution was utilized to estimate the interface position of THF hydrate layer around a planar probe. In said method, the polynomial (order 2) and exponential assumptions were introduced as temperature profile for solid and liquid phases in finite regions. A proper agreement was found between the results of mentioned solution and experimental data with average deviation about 3.5%. Also the parametric curves were presented to describe the effect of operating parameters on the interface motion between hydrate and liquid phases. The hydrate formation based on subcooling driving force is very effective to solve the separation difficulty between hydrate crystals and solution in water desalination procedure.
