This presentation describes how the combination of equation-based general-purpose modelling technologies and next-generation digital application framework provide an environment for easy construction and application of fast, robust online utility system models. A real industrial example is presented where PSE’s tool gPROMS Utilities and PSE’s gPROMS Digital Applications Platform are used to develop and deploy a digital twin of a steam system. The twin is linked to plant data systems, updating itself through machine-learning capabilities, validating actual performance and, where appropriate, identifying departures from normal operation. Cost-reducing operating changes are highlighted. Visualisation of the twin is seen to be critically important to give operators greater insight and confidence to run the process safely at the optimum point, thereby making a major contribution towards Operational Excellence.
