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 .
Residual oil is oil found in low concentrations naturally or in exhausted oil fields. Often mixed with water, it cannot be recovered by conventional techniques. However, part of it can be recovered using carbon dioxide-enhanced oil recovery (CO 2 EOR) which involves injecting carbon dioxide into the well reducing viscosity and enhancing flow of the oil.
Number 5 fuel oil is a residual-type industrial heating oil requiring preheating to 77–104 °C (171–219 °F) for proper atomization at the burners. [8] It may be obtained from the heavy gas oil cut, [ 7 ] or it may be a blend of residual oil with enough number 2 oil to adjust viscosity until it can be pumped without preheating. [ 8 ]
For diesel engines it depends on the type of fuel, for distillate fuels the cetane numbers are used. Cetane numbers are tested using a special test engine and the existing engine was not made for residual fuels. For residual fuel oil two other empirical indexes are used: CCAI and Calculated Ignition Index (CII).
The ocean shipping industry has long served as a veritable ‘garbage dump' for the global refining industry. The dregs of the refining process, the residual high-sulfur fuel oil (HSFO) left at ...
Much like No. 6 fuel oil , mazut is a refinery residual product, that is, products left over after gasoline, diesel, and other light distillates are distilled from crude oil except, unlike bunker fuel, mazut is produced from much lower grade feedstocks.
The facility still holds 64, 000 gallons of "residual fuel " that will require different techniques to remove. JTF-RH will remove 60, 000 gallons of it, while the rest will be removed by a new ...
Nearly 38% of residual fuel oils are consumed in the shipping sector. In the process of converting excess residual oils into lighter oils by coking processes, pet coke is generated as a byproduct. Pet coke availability is expected to increase in the future due to falling demand for residual oil.
