Solutia to enhance nitric acid production

– Solutia, 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. 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 thermodynamic models, and the correlations for calculation of reaction, dimerization or equilibrium constants.
