Process improvement through process integration. - 106 p.

Director: Mahmoud El-Halwagi.

Thesis (Ph.D.)--Auburn University, 2002.

Process improvement is among the key functions of a technology group in any chemical process industry. It includes activities that focus on making an existing or a new process more efficient. Process improvement endeavors are typically aimed at getting higher yields, process debottlenecking, process simplification, reduced manufacturing cost, more energy efficiency, reduced loss of valuable species, and reduced waste discharges. This dissertation has introduced new techniques for process improvement and waste reduction for existing and new processes. Focus has been given to retrofitting the design of existing processes and for developing grass-root designs of processes with simplest configurations. In the retrofitting area, two important pollution-prevention problems have been addressed. The integrated design of reaction and separation systems: graphical and mathematical techniques have been developed to simultaneously design reactors and separators. This way, systematic tradeoffs are established between the two systems with the result of minimizing total waste at minimum total annualized cost. The solution procedures involve the identification of optimum targets, allocation, segregation, mixing, and processing strategies.

This dissertation has introduced new techniques for process improvement and waste reduction for existing and new processes.

In the retrofitting area, two important pollution-prevention problems have been addressed. The integrated design of reaction and separation systems: graphical and mathematical techniques have been developed to simultaneously design reactors and separators.

The solution procedures involve the identification of optimum targets, allocation, segregation, mixing, and processing strategies.
520 $a An optimization based procedure has been developed to add reverse osmosis networks to existing facilities so as to reach targeted waste reduction duties at minimum cost. The devised procedure is based on combining the right level of modeling details with an allocation framework. The solution identifies optimum configuration, size, and flow distribution for the reverse osmosis network
520 $a In the area of grass-root design, this work has introduced a new problem on process simplification along with graphical and mathematical solution procedures. The process simplification task is aimed at synthesizing process configurations that involves the least number of processing steps while yielding a certain product from a set of raw materials. New concepts of maximum extendable zones and product paths have been introduced and incorporated into the design procedure. The solution identifies the simplest processes along with their configuration, stream distribution, and basic performance data
