Determining of the Residence Time Distribution in CPC reactor type

The objective of this study is to characterize a tubular reactor. The experimental set-up consists of a collector with a capacity of 20L consisting 05 glass tubes connected in series. The characterization of the reactor is made using determination of residence time distribution RTD, knowledge of the various parameters of the RTD is an invaluable diagnostic tool that allows realizing the overall operation of the reactor hydrodynamic and detecting anomalies flow. The experimental results show the photereacteur dysfunctions. From the results of the RTD we can determine the Peclet number P-e and dispersion coefficient Da. Peclet number values are measuring range from 20 to 60, and those of the dispersion coefficient Da are very low between 2 and 8.10(-3) m(2)/s. Knowledge of these values directs us to given an appropriate flow model. (C) 2010 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of The TerraGreen Society.
