Entering the new semester in September, one of the subjects that I take is Principle of Chemical Processes 2. The pre-requisite of this subject of this subject is PCP 1. Basically, in this semester, this subject is more related to energy balance. However, we still need to apply basic mass balance as the introduction of more advance calculation.
In Chapter 8, we learn about state properties, hypothetical process path, and procedures on how to perform energy balance. In hypothetical process path, we learn the step by step on how a substance changes its phase from one to another. It’s not just the phase that is changing; the temperature and pressure also change. However, only one of these things is changeable, and the other remains constant. We also learn Watson Correlation, Kopps Rule, Raoults Law, and we use the Anotoine equation again.
In this chapter also, we learn how to use psychometric chart. It’s a chart that consist of many variables, which is dew point temperature, humid volume, saturation heat, dry bulb and wet bulb temperature and many more. From this chart, we could get many information that can be used in our calculation for the problem given.
Lastly, we learn about adiabatic humidification. Adiabatic means that the heat removed or gains to or from the surrounding is zero. However, in the book, it states that the heat still exists but only during the process of gas to become liquid. So that’s the end of my reflection of chapter 8.
That’s all from me. TQ
