Abstract:This work focuses on the heat exchange between a polymer particle and the reactor wall for low gas velocities. The role of different wall materials (or heat transfer conditions) is investigated with an eye to understanding how this influences the likelihood of build up of wall sheeting via melting of particles. The temperature profiles inside growing polymer particles in the vicinity of the reactor wall when it is clean (steel) or covered with a layer of non-reactive polymer are simulated. As a comparison, we have also simulated glass reactor walls to represent bench-scale polymerisation equipment. The results can help to understand how how we can compare results from bench-scale experiments to industrial scale units.
