Question
You cam an internship for the summer at a steam-methane reforming plant and are assigned a
huge project, the instillation of a recycle to improve the conversion of CH4 You develop the
process shown below. The reaction describing the process above is govemed by the following
equation
CH4 + H20 → CO + 3H2
The process deseription is as follows.
1. 125 mols of total fresh feed is fed to the process. This fresh feed is comprised of 50 mole
percent CH4.
2. The process is designed for 95% overall conversion of CH4.
3. Only CHa and H;0 are recycled.
a. 92% of the unreacted CH4 is recycled.
b. 40% of the unreacted H20 is recycled.
a. Completely label the diagram.
b. What is the recycle ratio?
e. What is the single-pass conversion of methanol?
