An on-line monitoring system (MoSys) based on dimensionless mass and energy balances with adaptive functions was developed to support the operational personnel during the optimal and environmentally compatible process control of the complex multi phase hydrogenation in stirred tank reactors. For industrial testing. MoSys was integrated in a batch-information-management system (BIMS) which was also developed and implemented in the process control system (PSC) of a multipurpose reactor installation. As a result, the outputs of MoSys, such as the progress of hydrogenation, the predictive end of reaction and concentration profiles, can simultaneously be visualised with imponant process signals on terminals of PCS. The efficiency of BIMS/MoSys could be proven during two industrial hydrogenation campaigns.
