Part 1

 

• KRD

I am amazed by how this subject makes me to think analytically and logically. Dr. Suzana is practicing active learning in during our lecture and Dr. Tazli is being very helpful in our project. Chemical kinetics and reactor design are at the heart of producing almost all industrial chemicals. From this project, I realized that the knowledge of chemical kinetics and reactor design is the pride of a chemical engineer because it distinguishes the chemical engineer from other engineers. I understand that as a future chemical engineer, I need to master a variety of chemical reaction engineering topics to face the challenges because my decision on the reactor can be the key to the economic success or failure of a chemical plant.

 

• CPDIC

I like the mathematical part and the designation of the control strategies of this subject. However, I find the derivation of the equations is confusing and complicated. Dr. Abbas is giving us good examples and explanation to help our understanding.  Process control and its allied fields of process modeling and optimization are critical in the development of more flexible and more complex processes for manufacturing high-value-added products. From this project, I realized that control systems are essential part of industrial. I understand that as a future chemical engineer, I need to master the concepts for dynamics, feedback and stability in order to be able to design and operate modern plants.

 

• PSLP

I enjoy studying this subject because the equations and solutions are more straight-forward as compared to the other two subjects. Dr. DZulkarnain is guiding us all the way by having solving the questions in the class. Process safety and loss prevention is important in chemical industry, which is entering an era of more complex processes, higher pressure, more reactive chemicals, and exotic chemicals. From this project, I realized that chemical engineers will need a more detailed and fundamental understanding of safety to face a more complex processes in the future. I understand  hazards need to be identified as early as possible so that action can be taken to correct or mitigate the situation.

 

Part 2

 

• KRD

Previously in chapter 4 Isothermal Reactor Design: Conversion, when the rate law is known, I can substitute into the mole balance and use the appropriate stoichiometry to analyze any isothermal reaction. In the second part of KRD, the rate law is unknown, I need to determine the reaction order and specific reaction rate from experimental data obtained from either batch or flow reactor using differential method, integral method, half-life method and initial rate method. I also learn about reactor selection for multiple reaction such as in series, parallel and independent. I realize that it is important to maximize the desired product and minimize the undesired product as one of the key success in the economic success of a chemical plant. Later on, I learn about the adiabatic operation of reactors and the heat effects in chemical reaction because most of the time the reactions are not carried out isothermally. I learn to develop the Energy balance to solve reactor design problems. Learning KRD is fun as it shows how crucial it is for chemical engineers to design and manipulate the reactor in order to support the industry. Dr. Tazli is very good in guiding us in solving the problem step by step, make sure that we truly understand the topic before proceed to the next chapter.

 

• CPDIC

In the second part of CPDIC, the syllabus are focusing on the Feedback Controllers. I learn about the standard feedback algorithms with emphasis on PID controller. Later, I learn about the closed loop system using block diagram where the knowledge of dynamic process, feedback controller and instrumentation are combined. As an alternatives to Laplace transform, I also learn how to use frequency response analysis to analyze dynamic system using the Bode stability criterion. Lastly, I also learn about the process instrumentation where basic component of P&ID and basic control instrument are discussed. Dr. Haslinda is very patient in explaining the concept to us. By having the tutorial sessions with her, we manage to understand better by solving the problem step by step with full explaination.

 

• PSLP

In second part of PSLP, for fire and explosion, I learn to estimate the magnitude and consequences of fire and explosion. To limit the potential damage from fire and explosion, I learn about how to prevent flammable mixture, prevent the initiation and minimize the damage after a fire or explosion.  Later, I learn about Hazards identification where HAZOP is implemented to Identify hazards in a chemical process facility.  Not only that, I learn about the risk assessment which includes incident identification and consequences analysis using probability and numbers. As an engineer, we need to make sure of the safety of ourselves and others. Incident can be prevented if we identify the hazards and perform risk assessment. Dr. DZulkarnain is very systematic and well organized in his teaching. During his class, assignments are given on the important topic so that we could understand better by solving the problems in class.

 

 

 

This is the first time for me to design a board game. So, when we started this project I planned to modify the existing board game in order to meet the theme and the objectives. Finally, my group decided to have our own board game called ‘Engenius’. Through is board game, I personally think that the process of completing the project is interesting and fun because I can actually imagine myself playing the game and I can alter the game as my wish. This is also my first time dealing with ‘Wix’, ‘Prezi’ and ‘Powtoon’. My group mates help me a lot in teaching me to use these applications. In the future, I would use these applications to transform my idea into graphics and animations and present to the others.

 

 

 

This board game focuses on a variety of industry namely the crude oil refinery, and power plant.

 

• KRD

The questions and problems are designed based on the chemical kinetic principles which includes the rate at which chemical reactions take place, the mechanism and rate-limiting steps that control the reaction process, the sizing of chemical reactors to achieve production goals. I think that the questions are well-designed because the player are answering the question based on modern plants having complex and highly integrated processes.

 

• CPDIC

The questions and problems are designed based on the plants’ dynamic behavior, basic control concepts, and advanced control strategies. The questions are mainly emphasize in operating a safe and efficient plant using the player’s knowledge in process control systems. The parameter that is controlled are mostly temperature, pressure and flow rate. I think the players will understand this subject better because they will constantly calculating and deriving the equations which I think is a good exercise after lecture.

 

• PSLP

The questions and problems are designed based on how to make sure processes are safe using techniques such as hazard identification and risk analysis, inherent safety concept in design and technological advances using better design or control. The questions emphasize the use of appropriate technological tools to provide information so that the player can make safety decisions with respect to plant design and operation in order to prevent hazards in the plant. Since the board game illustrates a modern plant, therefore I personally feel that the players will realize the importance of safety as well as the consequences when a hazard happens.

 

 

 

 

In this project, we are given a task to propose a technology to change the waste from Tesco Sri Iskandar to wealth. I personally think that the topic itself is very interesting as this project is the platform for use to apply all the knowledge of what we have learn from our first year up to now. The topic is closely related to the current subjects that we are taking now in 3rd year 1st semester. This is because we are required to design a reactor for our technology (KRD), to develop the control element of the reactor (CPDIC) and to perform HAZAP analysis (PSLP). The knowledge that we get from the textbook and lecture notes are very limited, therefore, we will need to find other sources to complete the project. This project is very challenging as in we only have around 6 weeks to complete. The process of developing P&ID diagram, mechanical drawing of the reactor, mass balance on HYSYS etc. is very time consuming. However, despite of the challenges we faced, I am very proud of my group as we are able to complete the mission impossible.
