OR YEARS, PROCESS SIMULATION WAS limited to the petrochemical industry and other related chemistries. Today, several simulation packages include aqueous thermodynamic capabilities that open process simulation up to a wide range of additional applications. This article will look at the theory of aqueous chemical equilibrium, its application to process simulators, and the application of simulatio...

This paper describes analytical and experimental efforts leading to a complete thermodynamic simulation of refrigerant screw compressors with emphasis on methods for inspection of experimental compressors and assembly analysis to determine actual clearances for specific test compressor. This work led to a better understanding of leakage and improved analysis in the thermodynamic model. The need...

Discontinuous molecular dynamics simulation and thermodynamic perturbation theory have been used to study thermodynamic and transport properties for a large number of organic compounds. The fundamental basis of the approach relies on a stepwise characterization of the disperse interactions and blister potentials for the hydrogen bonding. It has been demonstrated that these types of attractive i...

Several numerical approaches have been proposed in the literature to simulate the behavior of modern blast furnaces: finite volume methods, data-mining models, heat and mass balance models, and classical thermodynamic simulations. Despite this, there is actually no efficient method for evaluating quickly optimal operating parameters of a blast furnace as a function of the iron ore composition, ...

The use of new and renewable energy for the application on gas burners is beneficial environment. This study aims to determine effect excess air during combustion producer from biomass gasification release heat used as a fuel burner. Simulations are carried out by applying mass balance, showing that an increase in will decrease non-adiabatic adiabatic flame temperature. result showed reduces am...
