Measurement and Computation of Physico-Chemical Properties of Sugar Solutions

Reduction of process steam demand and water-usage through heat integration in sugar and ethanol production from sugarcane – Evaluation of different plant configurations

“…It was done because the default parameters of the simulator do not represent appropriately the behaviour of sucrosewater solution at equilibrium. Moreover it was necessary to create a subroutine in Fortran from empirical correlations [36] and link it to the simulator in order to calculate specific enthalpies for these solutions. It was performed because the sugarcane juice is a complex mixture of water, sucrose and impurities [33].…”

“…Mass Density of the Mother Liquor. A correlation obtained by Kadlec and co-workers , is used to calculate the mass density ρ sol of the mother liquor (an impure sucrose solution), as a function of the temperature T , dry substance content B sol , and purity P sol . In that correlation, ρ sol is written in terms of the mass density ρ sol,p of a pure sucrose solution (with the same dry substance content as the impure solution), as follows: where For the present work, the following correlation, which was obtained by Emmerich, is used to calculate the mass density ρ sol,p of the pure sucrose solution: where is the mass density of liquid water and with and Values of the coefficients in eqs A10−A14 are given in Table A1.…”

“…A correlation obtained by Kadlec and co-workers 51,52 is used to calculate the mass density F sol of the mother liquor (an impure sucrose solution), as a function of the temperature T, dry substance content B sol , and purity P sol . In that correlation, F sol is written in terms of the mass density F sol,p of a pure sucrose solution (with the same dry substance content as the impure solution), as follows:…”

“…If the massecuite is regarded as a suspension of crystals in the mother liquor, the ideal solution approximation may be used for writing its mass density F mc , as follows: 49,51,52 where F c is given by eq A1 and F sol is calculated from eqs A2-A16.…”
