Anchor Tenant Approaches in Process Integration and Design
Abstract
Global chemical demand is growing at a significant rate as it is driven by population growth. This growth entails the increased usage of resources and environmental stress if a business as usual approach is taken. Economic gains and the mitigation of these growth effects could be achieved through the adoption of EcoIndustrial Park (EIP) practices where intermediate and waste streams from one manufacturing plant are exchanged with another. It is of interest to develop methodological approaches to facilitate the design of EIPs that will enable increased production efficiency. A subset class of EIPs, Carbon-Hydrogen-Oxygen SYmbiosis Networks (CHOSYNs), and their design is focused upon. The concept of CHOSYNs leverages the foundation of the hydrocarbon processing industry by utilizing material streams containing carbon, hydrogen and oxygen atoms to create synergies among participating facilities. It is important to account for the various relationships between the EIP participants when synthesizing a new CHOSYN or retrofitting an existing system. The Anchor-Tenant model is adopted to account for these relationships in the synthesis of CHOSYNs. “Anchors” are first invited as key participants that provide the foundation within the EIP. “Tenants” are potential plants that could be developed and integrated with existing “Anchor(s)” thus creating a genesis of an EIP. Multiscale optimization approaches are developed to identify and screen the tenants and to determine performance benchmarks for individual plants and for the whole EIP.
An approach is initially developed to synthesize CHOSYNs while considering the material throughputs of the anchors and tenants. Next, this approach is extended to include an additional tenant screening step that considers the transfer of energy between EIP participants. A case study is solved to illustrate the application of these methods.
