DESCRIPTION :- The setup consists of a glass column packed with Rasching Rings and two overhead feed tanks. Reactants are fed to the reactor through liquid distributor, fitted at the bottom of the column. Rotameters are provided to measure the individual flow of Chemicals. The flow rate can be adjusted by operating the needle valves provided on respective Rotameter. Samples can be taken periodically from the top outlet of reactor. EXPERIMENTATION :- Sponification Reaction studies in Packed Bed Reactor. To determine the Reaction Rate Constant.
