Chemical equilibrium of the CO2-carbonate system in a natural hypersaline environment
(Instituto Politécnico Nacional (IPN), Centro Interdisciplinario de Ciencias Marinas, 1994-07-01)
Samples of brines located at Isla San José, Baja California Sur, México, were collected in order to measure salinity, total alkalinity (TA), carbonate alkalinity (CA), total inorganic carbon (TCO2), and the first apparent ...
Modeling of syngas composition obtained from fluidized bed gasifiers using Kuhn–Tucker multipliers
This work aims to develop a modified chemical equilibrium model to accurately determine the syngas (synthesis gas) composition obtained from fluidized bed gasifiers. In order to do so, an optimization method was applied ...
Modeling of Phase and Chemical Equilibrium on the Quaternary System Acetic Acid, n-Butanol, Water and n-ButylAcetate
(The Berkeley Electronic Press, 2009-09)
The correlation of the data for phase and chemical equilibrium in acetic acid-n-butanol-watern- butylacetate is presented. The azeotropic properties, the topological structure and the existence of a reactive azeotrope are ...
Thermodynamic Assessment of Chemical Equilibrium for the Synthesis of Solketal in the Liquid Phase
(Wiley VCH Verlag, 2021-05-05)
The synthesis of solketal is one of the innovative routes of glycerol valorization to value-added products, and the simulation of the process requires the knowledge of thermodynamic properties that are not still available ...
Two dimensional numerical simulation for compressible flow in thermo-chemical equilibrium
In this paper, a finite difference scheme for the solution of the unsteady and steady, two dimensional Euler equations, considering working gas in thermo-chemical equilibrium, is presented. Three variations of the Total ...
A scheme for inviscid compressible flow, considering a gas in thermo-chemical equilibrium
(World Scientific, 2015-06)
A finite volume scheme for the solution of the unsteady 1D Euler equations, considering the working gas in thermo-chemical equilibrium, is presented. To achieve total variation diminishing (TVD) properties in the numerical ...
(Ediciones Universidad de América, 2018)
En este capítulo se definirá la espontaneidad pero en reacciones químicas. Se define entonces la energía libre de Gibbs para reacciones químicas como un criterio de espontaneidad cuando en un sistema reaccionante, los ...
Calculation of liquid-liquid equilibrium of aqueous two-phase systems using a chemical-theory-based excess Gibbs energy model
(Brazilian Society of Chemical Engineering, 2004)
