From challenge to opportunity: Enhancing oil refinery plants with sustainable hybrid renewable energy integration

Abstract

The research conducted a comprehensive techno-economic analysis and optimal design of a hybrid renewable energy system (HRES) integrated with grid connection, utilizing a case study focused on an oil refinery plant. The study explores the feasibility of incorporating solar, wind, and biomass energy sources alongside the existing Natural Gas Combined Cycle (NGCC) power plant and grid connection to meet the substantial energy demands of the refinery. By considering technical parameters and economic factors, including energy purchase prices, inflation rates, and environmental considerations, the research evaluates three distinct scenarios encompassing various combinations of the dedicated NGCC power plant, grid connection, and renewable energy sources, providing a holistic assessment of the energy supply strategies. The results reveal that the integration of renewable energy sources, especially in the context of reduced grid capacity, can lead to about a 44.6% reduction in carbon dioxide emissions and approximately a 32% reduction in net present cost compared to the base design without any renewable energy integration. This significantly enhances the economic viability and environmental sustainability of the oil refinery plant, contributing valuable insights into the optimal configuration of hybrid energy systems for large-scale industrial applications and addressing the challenges of energy security, cost-effectiveness, and environmental impact. © 2024 Elsevier Ltd
