This essay focuses on a vapor at the operating conditions. simple example of boiling a pot of water, there are many processes which may contain a substance
a chemical engineering question and need support to help me study.
Hi I am gonna have 10 multiple choice questions on these topics 1/ Multiphase Systems Containing a Single Condensable Component 2/ Energy and Energy Balances material attached
Like the simple example of boiling a pot of water, there are many processes which may contain a substance capable of being both a liquid and a vapor at the operating conditions:
The above example was a simple one: air and water. Why?
If we continue with our water/air mixture, we could calculate the composition if we fixed the temperature and pressure (since we only had two degrees of freedom).
At equilibrium, this system would obey Raoult’s Law (for a single condensable species):
In real multi-phase, multi-component processes it is often the case that we have multiple components in both the liquid and gas phases. This makes the problem of using physical laws to determine these compositions more difficult. (But the Gibbs Phase Rule still applies for determining just how much we can theoretically calculate)
In this course, we will not deal with mass transfer operations. (You will learn that in a year or two), so we will not discuss how a system. Actually gets to equilibrium or how fast it gets there, but we will simply accept the fact. That it is or is not at equilibrium.
There are a number of important definitions that will help us clearly discuss vapor-liquid systems in equilibrium.
