Abstract

This chapter presents an integrated methodology for inherent safety and waste minimization analysis. The task for the integrated analysis can be defined as follows: by giving the details about materials involved, process chemistry, flow sheet, and the reaction and separation schemes of a chemical process plant, the goal is to identify opportunities to minimize the hazards and wastes in that process by evaluating the synergies and tradeoffs between the two. The methodology and intelligent system for integrated analysis based on a material-centric approach is discussed. These are illustrated on an acrylic acid production case study. Acrylic acid is produced by the partial oxidation of propylene in a fluidized-bed-catalytic-reactor. Reaction products are quenched immediately using cold quench recycle, and off-gas is absorbed using de-ionized water. The quenched stream is sent to extraction column in which diisopropylether is used as solvent to separate the products from waste streams. Synergy with respect to change in operating conditions in reactor and trade-off with respect to change in operating pressure in off-gas absorber to improve safety and environmental performance has been identified.
