  RTD Studies In Continuously Stirred Tank Reactor

  Real reactors do not satisfy the idealized flow patterns, back mix flow or plug flow deviation from ideality can be due to channeling 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. The setup consists of one feed tank through which water is fed to the reactor. To predict the exact behaviour of a vessel as a Chemicals reactor, RTD or stimulus response technique is used. Steel is provided for understanding the R.T.D. characteristics. Pressure Regulator & Pressure Gauge are fitted in the compressed air line. The flow rate can be adjusted by operating the needle valve and measured by Rotameter. The compressed air is used for circulation of feed. The continuously stirred tank reactor made of Stainless

  RTD Studies In Packed Bed Reactor

  The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. 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. Axial diffusion and dispersion of fluid in packed beds are important for design and operation of separation equipment and Chemicals reactors. The tracer technique, the most widely used method for the study of axial dispersion. In stimulus response experimentation, we perturb the system using pulse input of tracer and then see how the system reacts or responds to this stimulus. The analysis of the response gives the desired information about the system. The setup consists of a glass column packed with Rasching Rings and one feed tank. Water is fed to the reactor through liquid distributor, fitted at the bottom of the column. Peristaltic Pump is provided to measure the flow of water. For understanding the R.T.D. characteristics, a special arrangement to inject tracer into the lower end of reactor, using a syringe, is provided. Samples can be taken periodically from the top outlet of reactor. The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer.

  RTD Studies In Plug Flow Tubular Reactor

  Real reactors do not satisfy the idealized flow patterns, back mix flow or plug flow deviation from ideality can be due to channeling 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 overhead feed tank through which water is fed to the reactor. The overhead tank system is used for circulation of feed. It is a helical coil tube type plug flow reactor made up of Stainless steel pipe. Reactants enter at lower end coming out of the top of coil from where samples are collected for analysis. For understanding the R.T.D. characteristics, a special arrangement to inject tracer into the lower end of reactor, using a syringe is provided.
