  Adiabatic Batch Reactor

  An adiabatic batch reactor is a closed system with no input and output streams. This reactor is operated under conditions like adiabatic (Temperature of Reaction Mass keep on changing), 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 set-up is used to study a catalytic homogeneous reaction under adiabatic condition. The set-up consists of a Dewar flask of capacity 1 lit. fitted with a stirrer. The flask is double insulated by ceramic wool insulation. Temp. is measured by digital temp indicator. The whole setup is mounted on a rigid M.S. frame.

  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.

  Combined Flow Reactor

  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 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 compressed air is used for circulation of feed. 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. Pressure Regulator, Pressure Gauge and Safety Valve are fitted in the compressed air line.

  Computer Controlled Chemical Reactor Service Unit

  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. Each reactor, mounted on a base plate can be attached to the service unit. The appropriate services such as feed circulation, instrumentation for temperature measurement & conductivity measurement for analysis are connected to the reactor, and it then becomes operational. This service unit comprises feed tanks, peristaltic pumps for feed circulation & Conductivity sensor for analysis. Flow of feed is controlled by computer signal. These all things are mounted on a compact and well-designed base for bench mounting. This is self-contained bench top service unit to accommodate the reactors, one at a time, for conducting experiments on the same 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.

  Computer Controlled Combined Flow Reactor

  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. 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.

  Computer Controlled 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)..
