Oil and gas companies play an important role in the global economy since they supply a
large portion of the necessary energy to the world. The optimal production of oil and gas …

In this paper, a novel integrated optimization approach which couples the up-stream refinery
and the down-stream ethylene plant is proposed. When the material balances of the …

Scheduling decision-making is often calculated and implemented using unreliable or
inaccurate data from process networks, therefore infeasibilities and inconsistencies in the …

Modeling and optimization of large-scale refinery scheduling problems is challenging
because of their complexity and size. Herein, we propose a mathematical model to …

We propose a discrete-time formulation for optimization of scheduling in crude-oil refineries
considering both the logistics details practiced in industry and the process feed diet and …

We develop a linear programming (LP) approach for nonlinear (NLP) blending of streams to
approximate nonconvex quality constraints by considering property variables as constants …

Due to quantity times quality nonlinear terms inherent in the oil-refining industry, performing
industrial-sized capital investment planning (CIP) in this field is traditionally done using …

A typical refinery consists of the production system and the utility system that are routinely
optimized in a hierarchical procedure. To meet the demand for higher profit and energy …

A major operation in petroleum refinery plants, blend scheduling management of stocks and
their mixtures, known as blend-shops, is aimed at feeding process units (such as distillation …

We propose a quantitative analysis of an enterprise-wide optimization for operations of
crude-oil refineries considering the integration of planning and scheduling to close the …
