Fuel oil is a fraction of crude oil distillation, primarily used as a fuel for heating, electricity generation, and marine propulsion. It is categorized into several grades based on viscosity and boiling point, including:
– No. 1 Fuel Oil: A light distillate, similar to kerosene, used in residential heating and small burners due to its low viscosity and easy ignition.
– No. 2 Fuel Oil: A middle distillate, commonly known as home heating oil, utilized in furnaces, boilers, and diesel engines for its balanced properties.
– No. 4, No. 5, and No. 6 Fuel Oils: Heavier residuals, often called bunker fuels, employed in industrial applications, power plants, and shipping for their high energy content and cost-effectiveness.
Production involves refining crude oil through processes like fractional distillation, cracking, and blending to meet specific standards. Globally, fuel oil demand is driven by the energy sector, with major consumption in Asia and Europe for shipping and power generation.
Environmentally, fuel oil combustion emits carbon dioxide, sulfur dioxide, and particulate matter, contributing to air pollution and climate change. Regulations, such as those from the International Maritime Organization (IMO), aim to reduce sulfur content in marine fuels to mitigate these impacts.
Economically, fuel oil prices fluctuate with crude oil markets, geopolitical events, and supply-demand dynamics, making it a key commodity in global energy trade. Alternatives like natural gas and renewables are increasingly challenging its market share due to sustainability concerns.
