Many nitric acid plants had been designed and erected by the Client based on its own technology. In order to complement the Client’s technological offer to its own clients, it was necessary to develop a dynamic model of the plant that would be used by the Client to show the plant operability to current customers as well as showing the plant and technology capabilities to future, potential customers.

A training tool for the operators of a chemical plant in Sweden was developed. An interesting technical challenge was solved by integrating the rigorous dynamic model in Aspen HYSYS with an emulation software of the Experion PKS from Proconex and an instructor station from Inprocess.
