ABSTRACT
The goals of the experiment is to investigate the effect of residence time towards the conversion
of the saponification process between Sodium Hydroxide, NaOH and ethyl acetate, Et(Ac).
The saponification process is done using the SOLTEQ Plug Flow Reactor BP – 101. The
product sample is taken for every flowrate of sodium hydroxide, NaOH and ethyl acetate,
Et(Ac) which is at 250mL/min, 200mL/min, 150mL/min, 100mL/min and 50mL/min for
titration process in Experiment 2 for the manual conversion determination. The residence time
for each flowrate is 8 min, 10 min, 13.3333 min, 20 min and 40 min, respectively. The
conversion of the reactant to product is 68%, 64%, 57.2%, 56.8% and 54.4%, respectively. The
reaction rate constant, k is 2.6563 L/mol.min, 2.2222 L/mol.min, 1.6706 L/mol.min, 1.6435
L/mol.min and 1.4912 L/mol.min, respectively. The rate of reaction, -rA is 0.002720
mol/L.min, 0.002879 mol/L.min, 0.003060 mol/L.min, 0.003067 mol/L.min and 0.003100
mol/L.min, respectively. The rate of reaction decreases as the reaction rate constant decreases.
Higher flowrate of reactant increases the rate of reaction and thus, increasing the conversion
rate of the reactant to product.

INTRODUCTION
In the industry, reactors are one of the most important equipment to create a desired products
from the raw materials. The design of a certain reactors are crucial. There are three types of
basic reactor which is Batch Reactor, Continuous Stirred Tank Reactor (CSTR), and Plug Flow
Reactor (PFR).
Plug flow reactor (PFR) or Tubular flow reactor consist of long hollow tube in which
the reactant would flow in an axial direction in the shape of plug (Cylindrical shape) as shown
in Figure 1. These tube usually encased inside the tank to maintain the temperature of the
system. In the PFR, we would consider the reactant is perfectly mixed and the composition of
the reactant is different along the tube. The streams are opposite of a batch reactor, which is a
reactor that has a constant volume and has no incoming or outgoing streams.
Figure 1 - Plug Flow Reactor Where the Reactant Flow In an Axial Direction in the
Shape of Plug
PFR become main choice for certain chemical process in the industry due to its nonmixing property of the reactors. It is also very helpful in the continuous production of the
product. Flow of plug flow reactor is laminar, as with viscous fluids in small-diameter tubes,
and greatly deviate from ideal plug-flow behaviour.
Basically, for chemical reactions, it is impossible to proceed to 100% completion. This
is because due to the rate of reaction decreases when percent completion gradually increases
until the point where the system achieve dynamic equilibrium (no net reaction occurs). In fact,
the equilibrium point mostly is less than 100% complete. Thus, distillation is used as a
separation process, in order to separate any remaining reagents or by products from the desired
product. Sometimes the reagents may be reused at the beginning of the process as a recycle
back, such as in the Haber process.

THEORY
Plug Flow Reactor (PFR) is one of the ideal reactor in industry. Many plants and company used
PFR as the site for their reactants to react in producing valuable desired product. This reactor
mainly famous for process that involves gas or fast reactions process. This is because, in PFR
the reactants are fed continuously and products are also continuously removed. PFR becomes
favourable because it is easy to maintain, as it does not have any moving parts. Additionally,
the most favourable reason is it has the highest conversion per reactor volume of flow reactor.
In designing and modelling a PFR, an ideal condition are assumed in order to ease the
calculation. The PFR behaviour are assumed to be perfect mixing at all times without dead time
occurs in any corner or area in the PFR. This composition is a function of residence time and
rate of reaction.
Figure 2 - The Schematic Diagram of A PFR
The ideal PFR mole balance with assumptions can be written as follows:
(Accumulation) = (in) − (out) + (generation)

DISCUSSION
In this plug flow reactor (PFR) experiment it is primarily to carry out a saponification reaction
between NaOH and Et(Ac). At the end of the experiment, the reaction rate constant is
determined by using formula and the effect of residence time on the conversion in the PFR.
This experiment are conducted using the SOLTEQ Plug Flow Reactor (Model BP 101) where
NaOH and Et(Ac) solution are fed into the reactor by varying the feed flow rates to obtain
several residence time and the effect of each one is studied.
Besides, a calibration curve for conductivity versus conversion is also prepared for
saponification reaction of ethyl acetate Et(Ac) and sodium hydroxide NaOH. For the
calibration curve of conductivity versus conversion, the slope and y-axis intercept value is
determined from the equation of the curve yield using excel. Based on Figure 4, the slope = 0.0424, while the y – axis intercept = 0.9406.
In this experiment, different initial feed flowrates, conductivity value and the volume
of NaOH used in the titration process is organized in Table 3. From the data, the residence
time, conversion of the reactions and the reaction rate constant is determined through a series
of calculation by using formula for plug flow reactor experiment.
A graph of conversion against residence time is plotted and it is shown in Figure 5. The
residence time and the conversion of the reaction is obtained from the calculation using
formula. The reactors residence time is defined as the reactor volume divided by the total feed
flow rates while conversion is a property that shows how much of the reaction take place which
is the number of moles of A that reacted per mole of A fed to the system.
From the graph plotted in Figure 5, the conversion of the reaction is inversely
proportional to the residence time of the reactant in the reactor. It shows that when the residence
time of the reactor increases, the conversion of the reactant will decreases. Residence time
shows the average amount of time that a particle spends in a particular system and conversion
is a direct function of time spent for reaction. Apparently, the higher the residence time, the
higher conversion. This may be due to the error of total feed flowrate of solutions occurred
while conducting the experiment.
The reaction rate constant, k for every different initial feed flowrate is 2.6563
L/mol.min for flow rate 250 mL/min. For flow rate 200 mL/min the k-value is 2.2222
L/mol.min and reaction rate constant for 150 mL/min is 1.6706 L/mol.min. For flow rate 100
LAB REPORT ON PLUG FLOW REACTOR (L5)
19
and 50 mL min the reaction rate constant is 1.6435 and 1.4912. We can see that the reaction
rate constant is decreased when the feed flowrate is decreased as well. Thus, showing that the
rate of chemical reaction at constant temperature depends only on the concentrations of the
substances that influence the rate according to the law of mass action.
The rate of reaction, -rA is also determined after the rate of reaction has been calculated.
The rate of reaction for 250 mL/min is 0.0002720 mol/L.min while 0.002879 mol/L.min is the
rate of reaction for 200 mL/min. For flow rate 150 mL/min, the rate of reaction is 0.003060
mol/L.min, 0.003067 and 0.003100 mol/L.min is the rate of reaction for flow rate 10 and 50
mL/min. It indicates that when the reaction rate constant is decreases, the rate of reaction is
also decreases. The specific rate constant is proportionally constant relating the rate of the
reactions to the concentrations of reactants. A rate law is an expression showing the relationship
of the reaction rate to the concentrations of each reactants.

CONCLUSION
From the experiment above, the flowrate of the sodium hydroxide, NaOH and ethyl acetate,
Et(Ac) is 250mL/min, 200mL/min, 150mL/min, 100mL/min and 50mL/min. The residence
time for each flowrate is 8 min, 10 min, 13.3333 min, 20 min and 40 min, respectively. The
conversion of the reactant to product is 68%, 64%, 57.2%, 56.8% and 54.4%, respectively. The
reaction rate constant, k is 2.6563 L/mol.min, 2.2222 L/mol.min, 1.6706 L/mol.min, 1.6435
L/mol.min and 1.4912 L/mol.min, respectively. The rate of reaction, -rA is 0.002720
mol/L.min, 0.002879 mol/L.min, 0.003060 mol/L.min, 0.003067 mol/L.min and 0.003100
mol/L.min, respectively. The rate of reaction decreases as the reaction rate constant decreases.
Higher flowrate of reactant increases the rate of reaction and thus, increasing the conversion
rate of the reactant to product.

RECOMMENDATIONS
There are several precautions and recommendations that we can do to ensure more accurate
and reliable results. Which is:
1) Repeat the trials at least three times and calculate the average results to get a more
accurate data.
2) Always make sure that the start-up procedure and shut down procedure was done
correctly to prevent damage at the equipment.
3) The flow rates of the inlet need to be kept constant by monitor it at all times because
the flow rates will affect the collected data.
4) Glass apparatus need to be handle carefully to prevent it from broken while conducting
