DESCRIPTION:

RTD Reactions:

Real reactors do not satisfy the idealized flow patterns, back mix flow or plug flow deviation from ideality can be due to channelling of fluid through the vessel, recycling of fluid within the vessel or due to the presence of stagnant region or pockets of fluid in the vessel. To predict the exact behavior of a vessel as a Chemicals reactor, RTD or stimulus response technique is used.

The setup consists of one feed tank through which water is fed to the reactor. The flow rate can be changed by varying the speed of peristaltic pump. It is a straight tube type plug flow reactor made up of glass.

For understanding the R.T.D. characteristics, a special arrangement to inject tracer into the lower end of reactor, using a syringe is provided.

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.
