Systematic process systems cost screening technique

Abstract

Selecting the best process design or retrofit alternative may involve preliminary cost screening. Note that, process screening can become a complex task when changes are introduced to interacting processes. This chapter describes a systematic hierarchical approach for cost screening that considers interacting process systems. A cost screening technique for preliminary process selection known as Systematic Hierarchical Approach for Resilient Process Screening (SHARPS) was introduced by Wan Alwi and Manan (2006) to pinpoint the best scheme that gives the highest savings within a pre-specified payback period by a designer. A water minimisation process screening case study is used to illustrate the technique.
