Correlation for estimating the effects of temperature on the viscosity of light hydrocarbon solvents

Correlation for estimating the effects of temperature on the viscosity of light hydrocarbon solvents Viscosity-temperature correlation has been developed for light hydrocarbon solvents. The correlation is based on one-parameter viscosity model developed by Puttagunta et al. (Chem. Eng. Res. Des., Vol 70, 1992, p 627–631) for conventional crude oils, which has been modified by incorporating a solvent viscosity reduction factor, Ф. The correlation was compared with the model of Puttagunta et al. on 22 light hydrocarbon solvents for a total of 318 data points. The average absolute deviation improves to 1.9%, compared with 2.2% obtained with the model over a temperature range from −54.41 to 160 °C. The correlation can accurately predict the viscosity of any light hydrocarbon solvent without the need to determine multiple characteristic parameters. This eliminates the consumption of time, energy, and money by costly and cumbersome calculations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Engineering and Performance Springer Journals

Abstract

Viscosity-temperature correlation has been developed for light hydrocarbon solvents. The correlation is based on one-parameter viscosity model developed by Puttagunta et al. (Chem. Eng. Res. Des., Vol 70, 1992, p 627–631) for conventional crude oils, which has been modified by incorporating a solvent viscosity reduction factor, Ф. The correlation was compared with the model of Puttagunta et al. on 22 light hydrocarbon solvents for a total of 318 data points. The average absolute deviation improves to 1.9%, compared with 2.2% obtained with the model over a temperature range from −54.41 to 160 °C. The correlation can accurately predict the viscosity of any light hydrocarbon solvent without the need to determine multiple characteristic parameters. This eliminates the consumption of time, energy, and money by costly and cumbersome calculations.
