1.0 SUMMARY:
The reactor test rig (RTR) experiment is purposely done to compare the performance of single stage CSTR, 3-stages CSTRs and PFR. The solutions that been used in this experiment is dilution of 0.1M of sodium hydroxide, NaOH and 0.1M of ethyl acetate, Et(Ac) to 60L. There are four common measures of reactor performance and the most important one is conversion. Then the speed is set to be at 300rpm and reading is taken every 5 minutes till the outlet conductivity remains constant. From the conductivity measured, the exit concentration of NaOH and the conversion percentage can be calculated by referring to the calibration curve plotted. The performance of reactors can be compared by relating the conversion of the reactants to become products with the Residence Time Distributions (RTD) spent. From the data collected, single stage CSTR spent 6.52 minutes, 3-stages CSTR spent 1.66 minutes while PFR 5.15 minutes. For factor conversion in the reactor, PFR showing the highest conversion value, which is up to 90.18%, followed by 3-stages CSTR which is 75.06% and lastly single stage CSTR which is 58.60%. The reaction rate constant and rate of reaction has been calculated and compared with these 3 types of reactors. For 3-stages CSTR, the Damnköhler (Da) number is calculated to estimate its highest conversion the reactor can achieved. The deep information is being discussed in discussion part and one reactor has been chosen to be the best reactor to be used to operate.
2.0 OBJECTIVES:
1. To compare the performance of single stage CSTR, 3 stages CSTRs, and PFR.
2. To decide which reactor is suitable to operate the reaction by comparing its performance.
3.0 INTRODUCTION & THEORY:
The Reactor Test Rig is a floor standing pilot-plant that can be used for demonstration on the difference in operating behavior of various types of reactor which are continuous stirred-tank reactor (CSTR), continuous stirred-tank reactor in series and plug flow reactor (PFR), using a
