  Isothermal CSTR

  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. Peristaltic Pumps are provided to measure the individual flow of Chemicals. The CSTR is fitted with stirrer for proper mixing. From top outlet of it samples are collected for analysis. Constant temperature water bath arrangement is provided to conduct the experiment at various temperatures.

  Chemical Reactor Service Unit

  This set-up is designed to conduct experiments on different types of chemical reactors on the same service unit. Different types of reactors i.e. Continuously Stirred Tank Reactor (CSTR), Plug Flow Tubular Reactor (Coiled Tube Type) and Batch Reactor (which will be supplied on extra cost) as separate units can be installed on the service unit individually one at a time for conducting experiments. Basically this range of small-scale chemical reactors represents the most common types of chemical reactor found in industry. The reactors use the saponification reaction between ethyl acetate and sodium hydroxide. This provides a well-understood and safe reaction for the students to investigate the different reactor types.

  Computer Controlled 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 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 varied by changing the speed of peristaltic pump. Samples are collected for analysis from the outlet of reactor.

  Computer Controlled RTD Studies In Plug Flow Tubular

  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 flow rate can be changed by varying the speed of peristaltic pump. It is a helical tube type reactor made of stainless steel. For understanding the R.T.D. characteristics, a special arrangement to inject tracer into the lower end of reactor, using a syringe is provided. 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
