DESCRIPTION:

CRE Lab- homogeneous

In an ideal CSTR (i.e. an ideal steady state flow reactor) the contents in reactor are well mixed and have uniform composition throughout. Thus the exit stream has the same composition as the fluid within the reactor. This type of reactor is known as mixed flow reactor. This set-up is used to study a non-catalytic homogeneous second order liquid phase reaction under ambient condition.

The set up consists of two feed tanks through which two reactants are fed to the reactor. Peristaltic Pumps are provided to measure the individual flow of Chemicals. The flow rate can be adjusted by operating the valves provided on respective Pump. The CSTR is fitted with stirrer for proper mixing. From top outlet of it samples are collected for analysis.

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Labview of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.
