Basic Principles and Calculations in Chemical Engineering

Chapter 7. Ideal and Real Gases

7.1 Ideal Gases

7.2 Real Gases: Equations of State

7.3 Real Gases: Compressibility Charts

7.4 Real Gas Mixtures

Your objectives in studying this chapter are to be able to

1. Understand the conditions under which the ideal gas law applies, and the conditions for which real gas relations must be used

2. Remember that the values of p and T used in relations to determine gas properties are absolute, not relative, values

3. Use partial pressure in calculations involving multicomponent ideal gases

4. Solve material balances involving ideal or real gases

In this chapter we begin to consider the physical properties of pure components and mixtures. By property we mean any measurable characteristic of a substance, such ...
