SKKK2123: Principle of Chemical Engineering Processes II
This subject is one of the subject that I must take in sem1 2012/2013. This subject is the continued of the subject principle of chemical engineering process I that I take last semester. The result that I got for that subject last semester is not as good as I think. There is more improvement that I must do to survive in this course. For the principle of chemical engineering process II there are learning outcome that that I must master to have a good result this semester sem1 2012/2013.
The first learning outcome is must have the ability to write basis, reference conditions and carry out unit conversion and equipment identification for various chemical process, process variable and unit operation in chemical industry. This ability is same with the previous process I. I can write the basis correctly. The addition is just I must know to put the right referent condition for the problem.
Then, I must have the ability to perform and solve energy balances with respect to changes in temperature, pressure and phase for non-reactive process. The energy balance is much simpler compared to mass balance. I just need to know how to read the energy table at the back of the book.
Then, I must have the ability to calculate the standard heat of reactions using Hess’ law, heat of formation and heat of combustion and then solve problem for reactive processes. For this part this easy because I have learnt in the matriculation first how to use Hess’Law. Thus I do not have much problem in solving any problem that containing Hess’law.
Then, I must have the ability to define the entropy and then calculate the entropy changes in a given process. To solve the entropy is hard for me because this is new topic. I need a lot time to understand the entropy.
Then, I also must have the ability to analyze and calculate the performance of power and refrigeration cycle. This learning outcome is the combination of what that I have learnt until now. I think I can understand more this topic if I do a lot of solving problem in the book.
Lastly, I must have the ability to conduct problem solving solution of mass and energy problem using principle of conservation.
The result of the first test is quit disappointed because I got a lot of mistake answering the question. It is improving in the second test. And I hope I do better in the third test. For the final examination I hope I in a good condition to answer the paper. To get a good result I need to put a lot of effort
hwaiting!!
