6.2 Real Gases: Equations of State

6.3 Real Gases: Compressibility Charts

6.4 Real Gas Mixtures

Chapter Objectives

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

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

• Use partial pressure in calculations involving multicomponent ideal gases.

• Solve material balances involving ideal or real gases.

Introduction

Consider the furnace and associated stack for discharging the flue gas to the atmosphere, shown in Figure 6.1. Assume that you want to design the stack (e.g., determine its diameter) based on the ...
