Divide into two teams which is the first team in charge of the CSTR 40L machine while the second team would carry out the back titration procedures. In a continuous-flow stirred-tank reactor CSTR , reactants and products are continuously added and withdrawn from the reactor. You just clipped your first slide! There are many reactors depending on the nature of the feed materials and products. The heater was not switched on until it was fully submerged in the liquid. The power for the control panel was turned off.

You just clipped your first slide! An increase of 10 oC typically doubles the rate of a reaction. A burette was filled up with 0. Controlled the valve carefully and slowly when adjusting the flow rate to make sure flow rate will stabilize and the experiment will run smoothly. See our User Agreement and Privacy Policy. Well mixed, therefore rA is the same throughout the reactor.

After 1 minute of reaction, 50 mL of sample was collected from the reactor. We need your help! The experiment steps 5 to 9 was repeated for different residence times by adjusting the feed flow rates of NaOH and Et Ac to about 0. The thermostat T1 was switched off.

The energy barrier or minimum energy a molecule must possess to overcome this barrier is called activation energy Ea which is can be shown in Arrhenius Law Equation: We need your help to maintenance this website. The conductivity and NaOH concentration for each conversion value were determined by mixing the following solution into ml of deionised water.


The slopes of the graphs which represent the specific reaction rate constant, k could also be obtained.

Therefore the experiment is success. Now customize the name of a clipboard to store your clips.

The CSTR model is used to predict the behaviour of serifs reactors, so the key reactor variables such as the dimensions of the reactor, can be estimated.

Both amount of activation energy are not too large for a reaction. The volume of NaOH solution titrated at 30oC. The mixture was then titrated with 0. The sample was titrated with sodium hydroxide, NaOH.


Fundamentals of Chemical Reactor Theory. Liquid level was maintained above the heater to avoid damage to the heater. The saponification process between this compounds produced sodium acetate in a batch and the continuos stirred tank 3.

Retrieved May 13, from http: Moreover, rate of reaction for NaOH or any species as reactant could be scirbd from the graph plotted using data. By the graph we can determine the rate of the reaction which is 2.

Both pumps P1 and P2 were switched off. A few drops of pH indicator were added into a mixture 5. The calibration curve is plotted to determine the conductivity of the reaction between NaOH and Et Ac at certain percentage of conversion. A chemical reactor may be characterized by the mode operation according to the flow condition.



Volumetric flow rate is related to the residence time therefore an experiment is conduct in varies flow rate which is 0. From the result and calculations, the data was fitted to second order reaction.

The seriew of Naoh been used in that titration has been recorded in the result. AIMS In this experiment, there are a few objectives to achieve: The rate of reaction is most important thing will be consider in the reactor because it showed the effectiveness of the processing of the reactor.

The unit comes complete with vessels for raw material and product,feed pumps and thermostat. The unit consist of jacketed reaction fitted in the agitator and condenser. ABSTRACT The experiment is to study the effect of temperature and reaction time and to determine the relationship between reaction rate with conversion, reactor volume and feed rate.

General Shut- Down Procedures 1. The volume of NaOH used was recorded.
