What is a straight run residual fuel?
Residual fuels represent the heavy yields from the refining processes. Straight-run fuel oils are “produced solely from atmospheric distillation and are generally used as an intermediate feedstock for further processing within the refining system to increase the yields of lighter products.”
What is straight run diesel?
The separation of diesel and gasoline hydrocarbons from crude oil occurs during the distillation process. Straight-run diesel and straight-run gasolines are the gasoline and diesel products that come out of the distillation column. But while flammable, straight-run gasoline is not a finished product.
What is VDU in refinery?
About 80% of the refineries operating in the United States have a vacuum distillation unit (VDU), a secondary processing unit consisting of vacuum distillation columns. To increase the production of high-value petroleum products, these bottoms are run through a vacuum distillation column to further refine them.
What is residual fuel oil used for?
The primary end use for residual fuel oil is as a fuel in simple furnaces such as power plants and industrial boilers. It is also the primary fuel used on ocean-going ships, where it is called bunker fuel.
What is residue fuel?
Residual fuel oil is the fuel oil that is manufactured from the distillation residuum, and the term includes all residual fuel oils, including fuel oil obtained by visbreaking as well as by blending residual products from other operations.
Is diesel easier to refine than gas?
Diesel fuel is heavier and less volatile than gasoline, which makes it simpler to refine from crude oil.
What does straight run naphtha mean?
Straight run naphtha is a basic constituent of refined petroteum products. It consists mainly of aliphatic hydrocarbons along with small amounts of naphthenic and aromatic hydrocarbons. It has a wide boiling range between 95°F and 410°F.
What is vacuum bottom?
Also known as: vac resid, residuum. Vacuum resid is the heaviest of the distillation cuts. It is, literally, the bottom of the barrel. Vacuum resid is the bottoms cut from the vacuum distillation tower. If not upgraded, vacuum resid is blended into either residual fuel oil or asphalt.
What is difference between crude oil and residual oil?
6 fuel oil (also called Bunker C oil or residual fuel oil) is the residuum from crude oil after naphtha-gasoline, No. 1 fuel oil, and No. 6 fuel oil can be blended directly to heavy fuel oil or made into asphalt. Residual fuel oil is more complex in composition and impurities than distillate fuels.
What kind of compound is straight run gasoline?
straight-run gasoline, alkylate, reformate, benzene, toluene, xylene) used for blending or compounding into finished motor gasoline.
Where does straight run fuel oil come from?
Straight run fuel oil is the residue that comes out from the distillation column, without further processing in vaccum distillation unit or residue catalytic cracker. API State Code Is..
What is the duty on straight run gasoline?
The duty on straight-run gasoline will be raised from $56,8 per tonne to $65,2 per tonne, with the export duty on commercial gasoline up from $48,8 to $56,0 per tonne. The duty on straight-run gasoline will be reduced from $63.9 per tonne to $56.8 per tonne, with the export duty on commercial gasoline down from $54.9 to $48.8 per tonne.
How does the straight line depreciation method work?
With the straight line depreciation method, the value of an asset is reduced uniformly over each period until it reaches its salvage value . Straight line depreciation is the most commonly used and straightforward depreciation method for allocating the cost of a capital asset.
