General Description
The Computer Controlled Continuous Stirred Tank Reactor for QRC, "QRCAC", designed by EDIBON, provides a controlled environment for detailed kinetic study of homogeneous liquid-liquid chemical reactions. This type of reactor, also known as CSTR (Continuous Stirred-Tank Reactor), is characterized by having the reactants in a tank where they are constantly stirred.
Through a series of practices, it allows for the determination of ionic conductivity, obtaining the reaction order with respect to different compounds, calculating rate constants, formulating rate equations, and analyzing the variation of kinetics with temperature. Additionally, it offers the possibility to compare theoretical and experimental results, study mixing effects, and perform operations both in batch and continuous modes. With the ability to calibrate temperature and conductivity sensors, the "QRCAC" is a comprehensive and versatile unit for training and research in chemical engineering, contributing to the advancement of knowledge in this field.
To work with this reactor, the Base and Service Unit, "QUSC", is required, which supplies the necessary reagents and thermostatic water for proper operation.
These Computer Controlled Units are supplied with EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
