- Heavy Fuel Oil (HFO) is a category of fuel oils of a tar-like consistency. Also known as bunker fuel, or residual fuel oil, HFO is the result or remnant from the distillation and cracking process of petroleum. For this reason, HFO is contaminated with several different compounds including aromatics, sulfur and nitrogen, making emissions upon combustion more polluting compared to other fuel oils. HFO is predominantly used as a fuel source for marine vessel propulsion due to its relatively low cost compared to cleaner fuel sources such as distillates. The use and carriage of HFO on-board vessels presents several environmental concerns, namely the risk of oil spill and the emission of toxic compounds and particulates including black carbon. Presently, the use of HFOs is banned as a fuel source for ships travelling in the Antarctic as part of the International Maritime Organization's (IMO) International Code for Ships Operating in Polar Waters (Polar Code). For similar reasons, an HFO ban in Arctic waters is currently being considered. (en)
- Les fiouls lourds (abrégés en FOL, ou HFO, de l'anglais heavy fuel-oil) ou mazouts lourds sont des combustibles à haute viscosité. Ce sont un mélange complexes d'hydrocarbures pétroliers : produits intermédiaires de distillats et de résidus de distillation en raffinerie ou d'une unité de craquage. Le mazout lourd mis sur le marché comme « carburant final » est habituellement un mélange de mazouts lourds et d’hydrocarbures de meilleure qualité employés comme diluants. Ils contiennent des hydrocarbures aromatiques, des aliphatiques et des cycloalcanes, dont le nombre de carbones varie entre C7 et C50 et dont le point d'ébullition est compris entre 121 et 600 °C. À noter que le mot fioul ne devrait pas être utilisé pour les fractions lourdes de la distillation du pétrole, car le fioul domestique est très proche du gazole. (fr)
