This work deals with on-line monitoring of exothermic chemical processes in stirred tank reactors. To support the personnel in the efficient and safe operation of batch processes, the monitoring system (MoSys) based on heat/mass balancing was developed. A model was implemented for estimating concentrations from heat/mass balances. Dimensionless balances with adaptive parameters were used to adapt the heat/mass balances to the chemical target reactor and to realise the scale-up. For industrial testing, MoSys was integrated in a batch-information-management system (BIMS), which was also developed and implemented in the process control system of a multipurpose reactor installation. As a result, the outputs of MoSys can simultaneously be visualised with important process signals on terminals of the process control system. Operational experiences in monitoring an industrial hydrogenation process are represented.
