How to explain chemical process calculations
Thread Content
As a lecturer in chemical engineering design, how should one explain chemical process calculations, as well as calculations related to materials, energy, and equipment? Nowadays, there are various calculation software programs available!
Hehe. . . Even when using software, you need to know the basic calculation methods. . I don’t think it’s necessary to go into detail about the horizontal calculation of materials and energy. . Even if it’s explained, not many students will be able to understand it. The key is to teach the students the methods and principles. There is no need to go into the specific calculation details. . Once the software is ready, explain to the students how to use it.
Personally, I believe that the use of software should also be based on an understanding of the basic principles of process calculation; it is most important for students to master these methods and principles
The basic principle behind material balance calculations is the law of conservation of mass, while the basic principle behind energy balance calculations is the law of conservation of energy. These two laws are fundamental to process design and calculation. The size of the equipment is determined based on material balance calculations, while the heating or cooling capacity is determined based on energy balance calculations. :lol
Solve various process calculation problems through examples. Cultivate students' ability to analyze and solve practical problems.
I believe a competent design instructor should help students understand that although software is user-friendly, those who do not understand its principles are unable to optimize operating conditions. The purpose of software is merely to free us from tedious calculation processes; relying on software excessively misinterprets the meaning of learning it.
You can find it online; you can use Xunlei, eMule, as well as literature databases!
In my opinion, although software with comprehensive functions is excellent as it essentially frees us from tedious calculations and seems to allow us to get rid of the complicated procedures of the past, the most fundamental knowledge remains what needs to be learned and mastered; basic knowledge is just as important as ever. Advice for the original poster: At the first level, proceed step by step, explain the knowledge in the books clearly, cover material balance and heat balance, and clarify some basic concepts and processes ； At the second level, specific examples are introduced and combined with what was discussed earlier; if these are integrated with the basic courses that students have taken previously, it becomes even more effective. At the third level, a particular software is used as an example to explain how to use that software, along with the basic principles of chemical engineering design that are relevant in its use ； If you can reach the third level, you will surely become an expert in teaching and an idol to your students.

Having software only reduces the computational workload on humans, but the fundamental principles must not be forgotten, such as energy conservation in chemical engineering.
:Victory: Thank you all for your support. The road ahead is long and arduous; I will keep searching hard.
Software is just a tool; without understanding the principles behind it, many of the options in the software cannot be set correctly, and as a result the calculations are inaccurate. Moreover, sometimes it is necessary to solve problems on the spot; without understanding the principles behind the calculations, it’s impossible to find solutions. Furthermore, for some commonly used data in engineering, the principles behind them are quite clear; applying them in actual design can yield twice the result with half the effort.
Based on an understanding of the basic principles of process calculation, students are taught to master the methods and principles involved. At the same time, various process calculation problems are solved through practical examples. Cultivate students' abilities.
This is better; through software-based instruction, the entire process can be explained to the students. Students rely too much on machines these days; they should be taught the principles and processes of calculation
