Implementation of Dynamic Simulation at Anglo Platinum

Paper i proceeding, 2014

The dynamics of process operation can be overlooked in design; often with considerable loss of throughput resulting from dynamic fluctuation and mismatch of units across a circuit. As a consequence, higher demand is on design of different control strategies. Designing a circuit with consideration of the implications an operation and control strategies have on the process is essential. The aim of this paper is to describe the modelling work done for this application and give an overview of the implementation of dynamic simulation platform at Anglo Platinum to support future debugging and tuning of the Advanced Process Control for a planned expansion. This paper builds on previous dynamic modelling work done at the Mogalakwena North Concentrator. The work is focused on system identification and the implementation of the Advanced Process Control algorithm in the dynamic plant model. The dynamic model of the plant was connected to the Advanced Process Control system and the response of the model validated against the behaviour of the plant.
