Robust Engineering Strategy for Solving Optimization Problems of Refinery Hydrogen System

Abstract Hydrogen is an important resource to upgrade refinery products. It is the second largest cost of refineries. Optimal scheduling of the hydrogen system will cut down on the energy cost and reduce carbon emissions in refineries. However, due to the mutability of the hydrogen generation and consumption, current scheduling methods may cause instability problems. This paper presents a robust engineering strategy that has been applied to hydrogen pipeline networks of a large-scale refinery. The implementation strategy involves four steps: model precision validation, solving efficiency validation, effect validation, and on field validation. The proposed strategy ensures the feasibility, necessity, and effectiveness of the previously developed mathematical model and solution approach.
