Supercritical water oxidation (SCWO) has the potential to be considered a clean energy generation process, as the process effluent is a high temperature, high pressure stream with a high enthalpy content that can be converted to heat and shaft work. In this work the state of the art of SCWO has been reviewed, focusing on energy production. For the description of thermodynamic and transport properties, there are some methods recommended for pure substances, but the applicability of those methods for mixtures at supercritical state is yet not clear. Most of the work found in literature use cubic equations of state and linear mixing rules. The design of reactors has evolved in order to reduce the drawbacks of corrosion and salt deposition, in general, through the dilution of reaction products. In order to make the process profitable energetically different strategies must be used to keep the products at the highest temperature without compromising the safety, and the hydrothermal flames if correctly stabilized are a good choice. Reactors and reaction systems able to process feeds consisting of suspension with high inorganic contents without diluting the effluent reducing its temperature must be developed. On the other hand, the systems of energy recovery must be improved, especially the expanders, in order to recover the pressure work as well as the thermal energy. Modeling tools can help in both aspects. But for developing good models a good comprehension of thermal and transport properties of mixtures at supercritical state, as well as oxidation kinetics under that condition are essential data that must be further investigated in order to find energetically efficient processes.

Isothermal vapor-liquid equilibrium was measured at 298.15 K for the systems methyl acetate + methanol and methyl acetate + methanol + CH3COOK, + LiCl, + CaCl2, and + Ca(NO3)2, by a saturation method. The results have been fitted by using the van Laar, Wilson, NRTL, and NRTL-m (a modified NRTL equation) activity coefficient models.

Isothermal vapor-liquid equilibria were measured at 298.15 K for the systems containing methyl acetate or methanol with the three nitrogen compounds acetonitrile, nitromethane and nitroethane, The experimental data satisfy the Redlich-Kister thermodynamic consistency test. The liquid-phase activity coefficients were fitted by using the van Laar, Mato, NRTL, Wilson and UNIQUAC equations. The systems with methyl acetate present slight positive deviations from ideality while the systems containing methanol exhibit strong positive deviations.

Vapor-liquid equilibrium data at 1 atm pressure for the systems n-Heptane-Isobutyl Acetate, Toluene-Isobutyl Acetate and Toluene-n-Butyl Acetate are reported. The data were well correlated by different thermodynamic equations. The behaviour of the systems Toluene-Isobutyl Acetate and Toluene-n. Butyl Acetate is close to the ideality.

Isothermal vapor-liquid equilibrium (VLE) data, at 25° C were determined by a saturation method for each of the six methanol or methyl acetate binary systems with dichloromethane, chloroform, and 1,2-trans-dichloroethylene. The experimental data satisfy the Redlich-Kister consistency test, and were correlated with five Gibbs free energy models. All the binary mixtures of methanol with the chlorinated compounds exhibit strong positive deviations from ideality while the mixtures of methyl acetate with the chlorinated compounds present negative deviations from ideal behavior.

Isothermal vapor-liquid equilibria (VLE) at 313.15 K and excess volumes at 298.15 K were measured for the binary mixtures of methyl tert-butyl ether (MTBE) with trans-1,2-dichloroethylene and acetonitrile. The liquid-phase activity coefficients were fitted by using the van Laar, Wilson, NRTL, and UNIQUAC equations. A minimum-pressure azeotrope was observed for MTBE + trans-1,2-dichloroethylene, while MTBE + acetonitrile exhibits a maximum-pressure one.

The local effective mole fraction (LEMF) equation shows abnormally poor performance in correlating and predicting vapor-liquid equilibrium data of binary and ternary systems when a binary pair exhibits negative deviations from ideality. This abnormal performance becomes progressively worse as the negative deviations from ideality increase, and it is a mathematical consequence of the negative value used in the LEMF equation for the non-randomness parameter alpha-ij.

A general method is proposed for formulating equations with which vapour pressures can be reproduced in wide reduced temperature ranges. The problem of low and high pressure extrapolation is discussed. The method is applied to vapour pressures of hydrocarbons and illustrated by results obtained with 160 compounds.

Isothermal P-x-y and excess volume data for methyl tert-butyl ether (MTBE) + dichloromethane, MTBE + chloroform, and MTBE + tetrachloromethane are measured. The vapor-liquid equilibrium data were reduced according to the maximum-likelihood principle. The system MTBE + tetrachloromethane shows an almost ideal behavior, while MTBE + chloroform shows strong negative deviations from ideality and exhibits a maximum-boiling azeotrope. The system MTBE + dichloromethane presents an intermediate behavior, with moderate negative deviations.
