§15§This book is based on full scale experience, and allows to understand the functioning of the slurry loop reactor, and to operate it. All necessary aspects of the reactor are treated, and then combined in a simple off-line model, valid for all commercial types of catalysts. A detailed method to scale-up products from the laboratory directly to the full scale loop reactor is given. §16§§This book presents all information necessary to understand the functioning of a slurry loop reactor for the polymerisation of ethylene into high density polyethylene, and to operate it accordingly. All discussions are based on experimental data from the operation of full scale commercial loop reactors. §Methods for off-line modelling and scaling-up from lab to full scale are included, as well as the answers to important questions on the running of two loop reactors in series. §Building knowledge from full scale industrial experience. This highly accessible book makes one understand the functioning of slurry loop reactors for the polymerisation of ethylene, and how to operate them. §Its methods include off-line modelling, scaling-up and running reactors in series. It is inspiring for all production and process engineers, showing, for the first time, how with full scale reactor data the link is made between firm basic theory and the most practical operating guidelines. §16§§§ §04§§§ §From the Contents:§ §The Loop Reactor Circulation Pump Power 15§The Functioning of the Settling Legs§The Settling of the Polymer in the Settling Legs§Catalyst Activity and Productivity§The 1/1 Hypothesis§Catalyst Residence Time Distribution§Catalyst Activity Profiles§Conversions§Ethylene Concentration Profile in the Loop§Simple Reactor Model§Correlations by Linear Regression§Scaling-Up from Bench to Loop§Two Loop Reactors in Series§§ §§ §02§Paul Allemeersch, Tessenderlo, Belgium.
