Holistic and versatile process integration framework for maximising resource efficiency

Abstract

This paper describes a new holistic and versatile process integration framework for maximising resource efficiency, The minimum resource targets can be achieved when all options for resource minimisation, including elimination, reduction, reuse/recycling, outsourcing, and regeneration, have been holistically applied using the resource management hierarchy as a guide. A sample of the use of this framework for energy minimisation is demonstrated in this paper together with a versatile tool which allows simultaneous targeting and network design, i.e. the Streams Temperature vs Enthalpy Plot (STEP). Systematic Hierarchical Approach for Resilient Process Screening (SHARPS) method is used for cost screening the various process changes to ensure a reasonable and practical payback period.
