DESCRIPTION:

Homogeneous Reactions:

This set-up is used to study a non-catalytic homogeneous second order liquid phase reaction under ambient condition in a combined reactor. It consists of two reactors connected in series, one is plug flow reactor and another mixed flow reactor.

In an ideal Plug Flow Reactor (PFTR) there is no mixing in the direction of flow and complete mixing perpendicular to direction of flow. Concentration of reactants varies along the length of reactor but not in radial direction. In case of a coil turbulence is introduced due to frequent change in direction of flow and presence of secondary flow, so a higher value of reaction rate constant is expected in coil tube type plug flow reactor.

In an ideal MFR (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.

The set up consists of two feed tanks through which two reactants are fed to the reactors fitted in series Peristaltic Pumps are provided to measure the individual flow of Chemicals. 1st is a helical coil tube type reactor made up of SS pipe. Reactants enter at lower end coming out of the top of coil from where it is fed to a MFR fitted with stirrer for proper mixing. 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 Lab view 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.
