Trang 11Key Principles for Analysis of Reacting
Systems
• Mass must be conserved
• Atomic species of a reacting systems cannot
be created or destroyed
Trang 12Analysis of Chemical Reactors and the
Connecting Disciplines
Chemical reactors are the linchpin in a chemical plant for
controlling, optimizing, manipulating
the transformation of matter through chemical reactions
Trang 13Example of Reacting System
Incomplete combustion of ethane
How is the reactor performance dictated by:
reactor temperature? (how does T varying within reactor)
residence time of reactor?
inlet/exit compositions? (how does Ci varying within reactor)
laminar vs turbulent flow?
use of catalysts?(homogeneous vs hetrogeneous reactions)
Output of reactor can be measured
