Inprocess was asked to develop the Espindesa Nitric Acid Digital Twin (ENADT) due to its experience in building dynamic simulation models with commercially available technology, as well as its proven skills in the development of software extensions to be run from inside such commercial process simulators, and also because of its long list of successfully deployed operator training systems (OTS).
Espindesa’s requirements for ENADT were established during the project definition stages. ENADT had to be a portable, high fidelity, dynamic, training instrument capable of accurately representing the behaviour of the equipment, the instrumentation and the implemented control strategy in the nitric acid plants, interacting with the user with a series of operator screens, specifically selected among the HMIs available in the control system databases.
