Solutia selects ProSimPlus for HNO3
optimisation
Solutia has selected the ProSimPlus HNO3 software to enhance and optimise the nitric acid production process in its Pensacola nylon plant in Florida
Solutia, one of the world's few fully-integrated producers of nylon 6,6 from intermediates to polymers, plastics and fibres, operates a single nitric acid plant at their Pensacola plant in Florida, that uses selective catalytic reduction (SCR) for NOx abatement "We wanted to find a simulation software that was tailored specifically for nitric acid plants," explains James Daniels, Team Leader of the Solutia Manufacturing Technology Department

ProSim releases a new version of Ariane, its unique software dedicated to the design and optimisation of energy power plants: it can be used both for offline studies, and online for optimisation
Braskem chooses Ariane to improve power plants
Braskem, the South American leader of the petrochemical industry, recently acquired Ariane to optimise its utility production, where it generates power and steam for the entire petrochemical complex
ProSimPlus HNO3 was specifically designed to address these types of processes.
The software provides a specific thermodynamic package that includes a complete database of the pure components involved in nitric acid production and in nitrous vapour absorption, the appropriate thermodynamic models, and the correlations for calculation of reaction, dimerisation or equilibrium constants.
These unique features, that enable the user to quickly build up an accurate simulation, have led Solutia to leave aside most of the general simulation packages available on the market.
As the objective was to be operational as quickly as possible and there was no time to be spent on the modelling of the complex chemistry and thermodynamics that occurs in the nitric acid manufacturing process, the choice was quickly made.
When evaluating the software, the Solutia process engineer responsible for nitric acid technology modelled the existing process in order to validate the simulation results.
"The comprehensive chemistry, the ease of use and the flexibility to model many different design scenarios convinced us of the capabilities of the software" adds Daniels.
The choice was also supported by the proven track record and reputation of ProSim, in particular in the nitric acid industry.
