#### Class 7: Equilibrium I

• Notes
• Compare EQ, PCC, WGS (needs streams.py)
• streams.py (right click, save as)
• This is a nice helper class for doing many of the calculations demonstrated previously.
• Uses Cantera
• Define the composition of the $\xi=0$ and $\xi=1$ streams.
• Functions provided for:
• compute $\xi_{st}$
• pure mixing state: h and y from, e.g. $h=h_0(1-\xi) + h_1\xi$
• products of complete combustion (x or y) and temperature for given $\xi$
• equilibrium products (x or y) and temperature for given $\xi$
• products of complete combustion with water gas shift equilibrium, and temperature for given $\xi$
• $\Phi$ from $\xi$ and $\xi$ from $\Phi$
• y from x and x from y
