Green Engineering: Environmentally Conscious Design of Chemical Processes

Chapter 10Flowsheet Analysis for Pollution Prevention

by Kirsten Sinclair Rosselot and David T. Allen

10.1 Introduction

The environmental performance of a process flowsheet depends on both the performance of the individual unit operations that make up the flowsheet and on the level to which the process streams have been networked and integrated. While Chapter 9 describes methods for improving the performance of individual unit operations, this chapter examines methods for assessing and improving the degree to which the unit operations are integrated. Specifically, Section 10.2 examines process energy integration and Section 10.3 examines process mass integration. The methods presented in these sections, and the case study presented in Section ...
