Make a sketch of a layout (plot plan only) of a process unit containing the following process equipment:

• 3 reactors (vertical—diameter 1.3 m each)
• 2 towers (1.3 and 2.1 m in diameter, respectively)
• 4 pumps (each mounting pad is 1 m by 1.8 m)
• 4 exchangers (footprints of 4 m by 1 m, 3.5 m by 1.2 m, 3 m by 0.5 m, and 3.5 m by 1.1 m)
• The two columns and the three reactors should all be aligned with suitable spacing and all the exchangers should have clearance for tube bundle removal.
