Simultaneous Site-Wide Energy, Waste and Production Optimization - Industrial Case Studies

摘要

In a petrochemical plant site, production, waste treatment and utility systems are three essential elements. They interact with each other via the flows of utility, waste and material, hence creating a lot of options and economic trade-offs among them. To obtain the optimal solutions for the trade-offs, site-wide bottlenecks must be located accurately. Then the three systems could be debottlenecked and optimized simultaneously. This paper proposes the Site-Model, a mathematical model, to debottleneck and optimize the petrochemical plant site site-widely. The model adopts a technique called the marginal value analysis (MVA) for achieving the task.
