CHAPTER 1
In our first class, we did recap about chapter 1. We also did discussion on application of simple reaction in our daily life. Interesting!
​
CHAPTER 2
Today class we did recap on chapter 2 and discussed the quiz. Later on we did jig saw activity. From there, I learn to work with my coursemate to solve the problem given. We shared our ideas to solve the problems. Then, we know on how to calculate the volume for flow reactor such as CSTR and PFR. We also discuss on arranging the best reactor in order to design the reactor with minimal volume which reflect the minimal costs. During jigsaw activity, I learn from the explaination of my coursemate. It is fun as I did not noticed time pass quickly.
​
CHAPTER 3
In chapter 3, I learn about reaction rate, how to do stoichiometry table, how to find initial concentration, expansion factor and how to determine the reaction order of a process. In this chapter, the rate law must be derived first from equations of previous chapter which indicates that this chapter are related to chapter 2 because from reaction rate we can substitute it into equation to calculate the volume of the reactor tank. Furthermore, as the reaction order increase, the formula for calculation become more harder.
For game tournament, I think it was a good thing so that I will always keep in track with what I'm learning right now. Plus, the game tournament also help to add some bonus mark for my test. However, I think after game tournament, we should the discuss the whole questions or Dr. Raihan can upload the complete answers to us so that we know how to solve the problems given to us.
​
Chapter 4
In this chapter, I learn about the how to correlate the mole balance design equation in chapter 1, the reaction rate law in chapter 2 and the stoichiometry table in the chapter 3. Plus, this chapter which is entitled isothermal desing reactor taught me how to calculate the volume for batch reactor and also for flow reactor. I this chapter, I was taught how to derive the equation in order to get the formula to calculate the required volume for reactor, the conversion of the process in the reactor. Therefore, in this chapter basically I learnt how to design the CSTR and PFR reactor. Next, from the video I also learnt that the scale up the any flow reactor can be done in the laboratory first by using batch reactor. This i sby determine the value of constank,k. Eventhough this chapter is quite tough for me, but in the class I managed to job down all the notes given by Dr Raihan and I still understand slow and steady on how to derive the formula to design the reactor. I think more exercise would help me in better understanding regarding this topic.
​
Chapter 5
In this chapter i learned how to analyse rate data by using 2 methods which are differential and integral method. This chapter also require me to carry what I’ve learned in the previous chapter. I learn how to integrate zero, first,second order analysis for irreversible process. In this chapter, Dr Raihan taught how to use the method of half lifes calculation and we did some exercise regarding it. Last but not least, she taught me about differential reactors which emphasis on the flow reactor. At first, i feel quit hard with this chapter same as in chapter 4. But after doing exercises and understand it at my own pace I started to grasp this knowledge. How that Dr Raihan can upload any exercises with solution for us to do as the final exam is around the corner.
​
Chapter 6
In this chapter, I learned about the types of reaction which are parallel and series. I learnt to calculate the selectivity, how to find Ca and how to maximise the desired reaction over the undesired reaction. Dr Raihan taught us how to determine the operating temperature of the reactor and which component need to be insert in excess in order to favor the formation of desired reaction. I also learnt how to determine whether the reaction is dependent on temperature or not based on the activation energy of each reaction. As this chapter involve in the PBL, it took m quite long time for me o understand it well. Even during PBL session i still cannot grab the main concept of this chapter. But then today after explaination from Dr tazli and exercises doen in the class conducted by Dr Raihan I finally get to understand it a little bit. Hope for the next semester I can understand this topic better.
​
CHAPTER 8
In this chapter, I learnt about how to give an appropriate suggestion for the best arrangement of reactor needed to perform a reaction especially for reversible reaction. We learnt on how to determine the order of the reaction and derive the rate law from it if it is reversible. We also learnt about the energy balance to find out the temperature increment as the process going on. Next, we learnt how to derive Xe in term of KC in order to ensure that our calculation is logical. About this chapter, we have done a take home test and from this test I got to know better about this chapter and obviously this chapter combine the mole balance, stoichiometry table and other things from earlier chapter. Hopefully I got quite high marks for take home test and doing well in the final.

Separation Process
CRYSTALLIZATION
In this chapter, I learn about the reactor that involve in crystallization such as draft baffle tube crystallizer, agitated tank, oslo type crystallizer and forced circulation crystallizer. I also learn the mechanism of each of these type of crystallizer. Then, I also learn the solubility curve in this and how to do material balance which the continuation from PCE. Plus, I also learn to do heat balance to calculate heat transfer in the crystallization process. But still, I do not have clear understanding about the full mechanism of crystallizer and when to use them in the industries according to final product demanded. I wish that I will learn more about the function of each crystallizer and maybe Dr Ekmi can upload the slides about these. Moreover, I wish that I could be more participated in the class so that I will get more understanding about this course in the future. In addition, if I’m not understanding about this course, I will definitely consult with Dr. Ekmi for clearance.
​
ADSORPTION
For chapter 2, I learn about the definition of adsorption, the type of adsorbent. Other than that, I also learn about the isotherm and how to determine them by using graphical solution. Next, I learn on how to material balance for the batch process of adsorption with the exercises provided by Dr. Ekmi in the class. Next, I learn about the mass transfer zone in fixed bed adsorption. This chapter is bit tricky when I have to understand breakthrough curve, I have to understand the breakthrough point, the ts, the fraction of total capacity, length of used and unused bed and also how to find the new value of each of these things I mentioned above if the condition changed. In the early stage, I find this chapter quite hard but thanks to Dr. Ekmi for giving us the tutorial question in the class that I managed to understand this topic well.
​
ion exchange
In this chapter, i learned about what is ion exchange, how does it happened, the resin, type of zeolites, and also the calculation for this chapter. During learning process, I feel fascinate to see how this ion exchange is being applied in the industry such as water softening and I can know where chemical engineers can play their role in the real life later on. However during learning this chapter, i found difficulty in doing the equilibrium relation. This is because I’m a bit slow in understanding the terms used in this chapter. However, i take a quick action where I learn this from my friend after the class session. However, in the future I hope that I can be more active in the class so that I can understand the lesson quickly in the class.
​
membrane separation
In this chapter, I learned about the definition of membrane. Besides, I also learned the mechanism for transport such as knudsen diffusion. Then I learned about the driving force for flow across membrane. Dr Ekmi also taught me on criteria assessing the membrane performance such as selectivity, permeability, permeance, permeatation flux. Last but not least, Dr Ekmi taught me the mass balance as calculation part in this chapter. In this chapter, I can understand the lesson quickly as Dr Ekmi did give us some exercise and I can understand the thing that need to be calculated such as flux, permeance, rate of diffusion across cross sectional area. Then, there is one time when Dr Ekmi did give us tutorial about this chapter so I get to understand this chapter better. Hope that more exercise will be given in the future.
​
evaporation
In this chapter, I learned about the definition of evaporation. I also learnt the factors affecting evaporation such as the feed temperature and solubility. I also studied to draw the diagram of evaporator for calculation. Dr Ekmi taught how to do the material and energy balance in the class. In this part, I tend to understand how to read the duhring table and etc. I knew that basic thermodynamic principal in being used in the calculation such as Hv, hf and hl. I also learned to calculate the steam used in the process of evaporation. I managed to understand this chapter because Dr Ekmi had given sufficient exercise in the class. I really enjoyed this class.
