  Computer Controlled Isothermal Continuously Stirred Tank Reactor

  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 isothermal condition. The set up consists of two feed tanks through which two reactants are fed to the reactor. The flow rate can be varied by changing the speed of peristaltic pump. The CSTR is fitted with stirrer for proper mixing. Constant temperature water bath arrangement is provided to conduct the experiment at various temperatures.

  Computer Controlled Isothermal Plug Flow Tubular 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. This set-up is used to study a non-catalytic homogeneous reaction under isothermal condition. 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. 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 varied by changing the speed of peristaltic pump. Reactants enter at lower end coming out of the top of coil from where samples are collected for analysis. It is a helical coil tube type reactor kept in a constant temperature water bath to conduct the experiment at various temperatures.

  Computer Controlled Isothermal Semi batch Reactor

  The set up consists of a Reactor fitted in a constant temperature water bath. Before starting the reaction the reactor is charged with measured quantity of one reactant. From a feed tank another reactant is fed to the reactor. Peristaltic Pump is provided to measure the flow of Chemical. One stirrer is fitted for mixing the reactants in reactor and other is fitted in water bath to keep the uniform temperature throughout in the bath. The temperature of bath can be maintained from ambient to 70 DegreeC with the help of Digital Temperature indicator Cum Controller. A isothermal semi-batch reactor is a semi-closed system with one input stream. It is operated under conditions like Isothermal (Temperature of Reaction Mass remains constant) and perfectly mixed (composition of reaction mixture is uniform throughout). This set-up is used to study a non-catalytic homogeneous reaction under isothermal condition.

  Computer Controlled 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. To predict the exact behavior of a vessel as a Chemicals reactor, RTD or stimulus response technique is used. The continuously stirred tank reactor made of Stainless Steel is provided for understanding the R.T.D. characteristics. This software package provides a comprehensive educational software environment within which the investigations can be performed. The setup consists of one feed tank through which water is fed to the reactor. The flow rate can be varied by changing the speed of peristaltic pump. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. 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 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.

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.

  Isothermal Batch Reactor

  A batch reactor is a closed system with no input and output streams. A batch reactor can operate under conditions like Isothermal (Temperature of Reaction Mass remains constant), perfectly mixed (composition of reaction mixture is uniform throughout), and constant volume (volume of the reaction mixture within the reactor remains constant, there is no appreciable change in the density of reaction mass). This setup is used to study a non-catalytic homogeneous reaction under isothermal condition.The set up consists of a Reactor fitted in a constant temperature water bath. One stirrer is fitted for mixing the reactants in reactor and other is fitted in water bath to keep the uniform temperature throughout in the bath. The temperature of bath can be maintained from ambient to 90 DegreeC with the help of Digital Temperature indicator Cum Controller.
