Acid dew-point (ADP) is the temperature at which the acid vapor, normally means sulfuric
acid (H 2 SO 4), in flue gas begins to condense. Acid condensation can result in low …

A comprehensive model has been developed for the calculation of speciation, phase
equilibria, enthalpies, heat capacities and densities in mixed-solvent electrolyte systems …

When cooling combustion flue gas for heat recovery and efficiency gain, the temperature
must not be allowed to drop below the sulfur trioxide dew point. Below the SO3 dew point …

The influence of simplifying assumptions of the electrolyte‐nonrandom two‐liquid (NRTL)
model in the derivation of activity coefficient expressions as applied to multi‐electrolyte …

Acidic combustion gases can cause rapid corrosion when they condense on pollution
control or energy recovery equipments. Since the potential of sulfuric acid condensation …

In this work, a thermodynamic-based model of an industrial phosphoric acid process is
developed. It consists of mass and charge balance equations along with equilibria and …

The electrolyte–NRTL model used in a previous work (B. Messnaoui, T. Bounahmidi, Fluid
Phase Equilibr. 237 (1–2)(2005) 77–85), was extended for modeling of α-hemihydrate and …

The wet-process phosphoric acid (WPPA) production is generally based on the use of
sulfuric acid (H2SO4) for phosphate ore attack. One of the main issues encountered in this …

The oxidation of ferrous ions in acidic sulfate solutions at elevated air pressures was
investigated. The effect of the Fe2+ concentration, initial H2SO4 concentration and partial …

This paper deals with the development of a thermodynamic-based model for the prediction
of fouling phenomena in a wet phosphoric acid process. The developed model is based on …
