The reliability of a chemical reactor depends on the capability of the control system to identify in time malfunctions that can take place during operation. In this work, carried out within the European Research Project AWARD, a new device for the early warning detection of runaway events has been tested. This device, based on the calculation of the divergence of the chemical conversion and reactor heat balance, allows the detection of anomalous reactor temperatures and the production of alarm signals. The reaction studied is the emulsion polymerization of acrylic monomers. In all the experiments the performance of the new device has been satisfactory.

Abstract
The reliability of a chemical reactor depends on the capability of the control system to identify in time malfunctions that can take place during operation. In this work, carried out within the European Research Project AWARD, a new device for the early warning detection of runaway events has been tested. This device, based on the calculation of the divergence of the chemical conversion and reactor heat balance, allows the detection of anomalous reactor temperatures and the production of alarm signals. The reaction studied is the emulsion polymerization of acrylic monomers. In all the experiments the performance of the new device has been satisfactory.
