Review demonstrates evolving chemical and biological desulfurization technologies in crude oil refining, highlighting persistent operational challenges for emissions compliance.
Key Points
Summarize scientific and technological progress in crude oil desulfurization processes and evaluate the technical challenges associated with reducing fuel sulfur content.
Conducted a technological review synthesizing published literature on crude oil refining and sulfur removal strategies.
Evaluated the operational mechanisms, advantages, and limitations of hydrodesulfurization, adsorption, oxidative desulfurization, alkylation, and biodesulfurization.
Refineries rely on diverse chemical and biological methods to convert or extract aliphatic and aromatic organosulfur impurities to prevent hazardous sulfur oxide emissions.
Each primary desulfurization route exhibits distinct trade-offs in operational complexity, processing conditions, and cost-effectiveness, necessitating further engineering optimization.
