Abstract
Developments in catalyst technology have played a major role implementing phthalic anhydride process improvements.
Steam turbines yield large energy savings, and are flexible in achieving a process heat/energy balance. Modern plants are major steam exporters, and depending on plant size, require 15%, or less, of the electric power needed in plants of the 1960's.
This paper briefly presents the more significant energy-saving developments of the process in the last two decades and discusses some aspects of design considerations which influence the energy balance.
