“…Direct integration of refining and ethylene cracking is considered as the essential building block in achieving the total petrochemical integration (Joly, Moro, and Pinto, 2002;Li et al, 2006). This problem has received more attention lately due to soaring motor gasoline prices and the directly related prices of ethylene feedstocks .…”

Achieving optimal integration between refineries and the petrochemical industry was, until recently, a far-fetched target. Now many refiners are engaging in feasibility studies to include and expand their share in the petrochemical market.In this chapter, we present a model for the design of optimal integration and coordination of a refinery and petrochemical network to satisfy given demand for chemical products. The main feature of the approach is the development of a methodology for the simultaneous analysis of process network integration within a multisite refinery and petrochemical system, thus achieving a global optimal production strategy by allowing appropriate trade-offs between the refinery and the downstream petrochemical markets. The performance of the proposed model is tested on industrial-scale examples of multiple refineries and a polyvinyl chloride (PVC) complex to illustrate the economic potential and trade-offs involved in the optimization of the network. 5.1

“…Direct integration of refining and ethylene cracking is considered the essential building block in achieving the total petrochemical integration. , This problem has received more attention lately due to soaring motor gasoline prices and the directly related prices of ethylene feedstocks . This kind of volatility in prices has prompted a shift in ethylene feedstock selection and economics to either lighter or heavier refinery product slates .…”

“…They demonstrated their method on two case studies: a single site refinery and a petrochemical complex. In another effort, a linear programming (LP) model for the integration of a refinery and an ethylene cracker was proposed . The evaluation for different crude types to optimize the refinery and ethylene cracker operations was implemented iteratively.…”

This paper addresses the design of optimal integration and coordination of a refinery and petrochemical network to satisfy given chemical products demand. The refinery and petrochemical systems were modeled as a mixed-integer problem with the objective of minimizing the annualized cost over a given time horizon among the refineries and maximizing the added value of the petrochemical network. The main feature of the paper is the development of a methodology for simultaneous analysis of process network integration within a multisite refinery and petrochemical system. This approach provides appropriate planning across the petroleum refining and petrochemical industry and achieves an optimal production strategy by allowing appropriate trade-offs between the refinery and the downstream petrochemical markets. The performance of the proposed model was tested on industrial-scale examples of multiple refineries and a poly(vinyl chloride) (PVC) complex to illustrate the economic potential and trade-offs involved in the optimization of the network. The proposed methodology not only devises the integration network in the refineries and synthesizes the petrochemical industry, but also provides refinery expansion requirements, production levels, and blending levels. The use of mathematical programming on an enterprise-wide scale to address strategic decisions considering various process integration alternatives yields substantial benefits. These benefits of process integration materialize in terms of economic considerations and improvements in the understanding of the process interactions and systems limitations.

“…In essence, the refinery provides olefins and aromatics as raw materials to the petrochemical plant. In return, the petrochemical facility improves gasoline quality adding highoctane components and supplies a fraction of the hydrogen needed by hydrotreating processes (Li et al, 2006). Moreover, a site-wide heat integration can reduce utility requirements for steam, electricity and water, thereby mitigating environmental impacts (De Oliveira Magalhães, 2009).…”

Integrated refinery-petrochemical facilities are complex systems that require advanced decisionsupport tools for optimal short-term planning of their operations. The problem can be formulated as a mixed-integer quadratically constrained quadratic program (MIQCQP), in which discrete decisions select operating modes for the process units, while the entire process network is represented by inputoutput relationships based on bilinear expressions describing yields and stream properties, pooling equations, fuels blending indices and cost indicators. We develop a novel decomposition-based
