REACTION CALORIMETER - A USEFUL TOOL IN CHEMICAL-ENGINEERING

For elaboration of chemical processes and construction of production plant a good number of process data is required. For this the reaction calorimetry is a sophisticated and practically orientated method. The user can investigate the reaction under realistic conditions in a small laboratory reactor. Today there are four types of instruments available on the market, which are more or less equal in terms of handling but totally different in the measuring principle. In the following report the main differences between all calorimeters will be presented. Furthermore, the special features of one measuring principle using heat flow sensors are demonstrated on a short example in the field of polymerization. © 1990.
