Reflection of courses
KRD, to me, is a very interesting subject that deals with the importance of choosing the right reactor for the right type of industry in order to produce the maximum results with safety, economic and social effects considered as well. This is indeed very important as it will highly affect the productivity of the industry or company, at the same time, it has its impact to the economy and the people. The beginning chapters of KRD seem easy as they consist of basic concepts of the subjects, and I am very curious to know and learn about how to apply these basic knowledge in the second half of the semester.
KRD
CPDIC
In my opinion, CPDIC is a subject that deals with handling a reactor in the right way, so it can complement to the design of the reactor, at the same time, does not cause any hazards during the functioning of the reactor. Although I had trouble catching up with the subject due to its complex calculation and understanding right at the beginning, I manage to cope up towards moving on to the next chapters by doing constant revision on the subject. It is really interesting to study how control system works, and how there is various equations for various situations in order to modify the control system of the reactor as preferred at that particular condition.
PSLP
As of now, I feel PSLP is revolving around some common sense of how to deal with situations where there are accidents in workplace, with the help of calculations that promote to risk management and damage control. It is indeed intriguing to read real life stories about accidents happening in power plant such as Chernobyl and Bhopal, and how many lives it has affected. It made me realize that process safety is indeed a very important aspect when considering the design of a reactor and managing the control system of it. It is by far the most important subject that actually affects the other two subjects, where one must always consider the hazard of a process or a design of a reactor before putting it to work.
reflection towards board game
This project was indeed a challenge for us that allowed the team to go beyond our comfort zone, where we had to read up and learn more about the subjects to be able to create High Order Thinking Skills questions that suits the board game. We chose Cluedo because we found the game to be attractive to players, while modifying it to suit the subjects, where rooms, suspects and causes of murder are replaced by accidents happen in a power plant, the location and the person working in the plant who is responsible of the accident. We struggled at the start of trying to implement the questions in the board game by finding the relation between all three subjects, however after meeting up with the lecturer, and getting the inputs of our teams as well, we managed to bring all opinions and ideas to the table and design a proper boardgame accordingly.
krd questions
The KRD questions are covering the basics of mole balance, rate law and stoichiometry equations. Developing HOTS questions for these basic chapters were very challenging, however I managed to get a little help from the sources in the internet to discover more about the chapters and developing conceptual questions based on that. One example is:
Eg. What specifically causes a CSTR in series to have a higher conversion than a CSTR in parallel?
When two CSTRs are in series, the first operates at a higher concentration, therefore the rate is greater, and the conversion is greater. The second reactor in series builds on the conversion in the first reactor. The conversion in the parallel scheme is the same as the conversion to the first reactor to the series scheme.
cpdic questions
The CPDIC questions were difficult to create based on HOTS as the subject as of now is a lot about calculation. But, through reading the textbook, I could come up with a few questions that revolves around the explanation of the calculations.
pslp questions
PSLP questions is the hardest to me because HOTS questions are more of recreating a situation and gauge people to answer it based on their knowledge on CPDIC and KRD. It was a challenge for me to create them, thus I came out with the basic questions for PSLP as it is best if the game had also easy and intermediate questions that can complement to the very difficult questions. One of the questions are:
Eg. State two (2) parameters that affect dispersion?
-
Windspeed
-
Ground conditions (building/water/trees)
-
Height of the release above ground level
-
Atmospheric stability
-
Momentum and buoyancy of initial material released
reflection towards project 2
Project 2 was a challenging process for me, as we were very busy with other projects with SEDEX around the corner. However, I find it really interesting and satisfying to actually do a real life application of what we are studying, it gave me a certain assurance that what I am studying as a Chemical Engineer can make a difference in terms of creating a technology that can help the community overcome waste management problems. Dealing the role as a leader, distributing tasks and ensuring each member finish their tasks on time was also challenging as each of us were busy with our own schedule, but we have finally pulled through it and hopefully it is a good project that we have submitted here. Overall I really enjoyed conducting the various challenges imposed in the questions of the project, and I look forward for more projects that can challenge our thinking like this.
