The solutions that been used in this experiment is dilution of 0. There are four common measures of reactor performance and the most important one is conversion.

Then the speed is set to be at rpm 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.

For factor conversion in the reactor, PFR showing the highest conversion value, which is up to The reaction rate constant and rate of reaction has been calculated and compared with these 3 types of reactors.

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.

To decide which reactor is suitable to operate the reaction by comparing its performance. The main assumption when using a CSTR is that the concentration of the incoming fluid will become instantaneously equal to the outgoing upon entering the vessel.

Or it can also be explained as it is a reactor that run at steady state with continuous flow of reactants and products; the feed assumes a uniform composition throughout the reactor, exit stream has the same composition as in the tank. At steady-state, the flow rate in must equal the mass flow rate out, otherwise the tank will overflow or go empty transient state.

While the reactor is in a transient state the model equation must be derived from the differential mass and energy balances. The equation of finding the volume of CSTR after rearrangement is: While a PFR consists in a long, straight pipe in which the reactive fluid transits at steadystate meaning that there is no accumulation.

The main assumptions when using a PFR reactor are that the fluid is completely mixed in any cross section at any point, but it experiences no axial mixing, contiguous cross-sections cannot exchange mass with each other.

PFR are often used in large-scale reactions, fast reactions, homogeneous or heterogeneous reactions and continuous production. The integral form of equation in finding the volume for PFR is: 4. 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 M of sodium hydroxide, NaOH and M of ethyl acetate, Et(Ac) to 60L.

Ashton Snellgrove Lab Partner- Christine Tran Chem – 4 TA - Yunli Hu Purpose To extract the active principle, an alkaloid, caffeine, from tea leaves. We will use tea bags as our source of raw material.

It will illustrate an extraction technique often used to isolate water-soluble weakly basic natural products from their biological source%(9). Lab reports are an essential part of all laboratory courses and a significant part of your grade.
