Abstract
Various advanced coal conversion-to-electricity processes are discussed in Chap. 1 that depend on the use of a gas stream comprised primarily of oxygen; therefore, air separation into its primary components, i.e., nitrogen (N2), oxygen (O2), and argon (Ar) are discussed within the context to CO2 capture. One of the dominant processes used for air distillation is cryogenic distillation. Cryogenic separation may also be used as a polishing step to enhance the purity of a gas stream predominantly comprised of CO2.

Notes
- 1.
Note that the definition of partition function in the field of statistical mechanics is different than this and refers to the sum over states corresponding to the energies associated with the electronic, vibrational, rotational, and translational degrees of freedom within a molecule.
- 2.
barg represents gauge pressure (P g ).
- 3.
bara represents absolute pressure (p a ), p g = p a − p atm.
