Solutia Inc. selects ProSimPlus HNO3 for the optimization of its Pensacola Plant.

Solutia Inc., one of the world's few fully-integrated producers of nylon 6,6 from intermediates to polymers, plastics and fibers has selected the ProSimPlus HNO3 software to enhance the nitric acid production process in its Pensacola plant (Florida / USA).

Solutia operates a single Nitric Acid plant utilizing 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 Manufacturing Technology Department.

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 vapours absorption, the appropriate property models, and the correlations for calculation of reaction or equilibrium constants. These unique features, that enable the user to quickly build up an accurate simulation, have led Solutia to leave aside all other 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, Solutia’s 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.
