Multi-stage CSTR reactor Unit (STR50)

This unit is designed to investigate the effect of various factors influencing the conversion of reactants and rate of a chemical reaction. This multi-stage unit is capable to study the plug flow pattern as an infinite number of mixed stages. Also each reactor unit can be used individually to carry out a specific chemical reaction. Each reactor unit operates in continuous mode with inlet and outlet streams and is equipped with heating/cooling coil. Two feed streams can be mixed together and enter the reactor simultaneously in co-current or cross-current patterns. Both feeds can be preheated in this unit and the flow rate of feeds are controlled by means of rotameters.
