What is a cutter stock?
Cutter stocks are generally lighter petroleum liquids than the heavy fuel oil produced by Russian refineries, which can be used to reduce viscosity to produce on-spec European fuel oil. The bulk of Europe’s cutter stock supply comes from US refineries.
What is fuel oil cutter?
Cutter stock is any stream that is blended to reduce the viscosity of the resulting blend. Fuel oil tends to be a sink for high-viscosity resid that must be offset by blending lower-viscosity material to meet the viscosity specification of the fuel oil. Common cutter stocks for fuel oil blending are LCO and kerosene.
What does a visbreaker do?
A visbreaker is a processing unit in an oil refinery whose purpose is to reduce the quantity of residual oil produced in the distillation of crude oil and to increase the yield of more valuable middle distillates (heating oil and diesel) by the refinery.
What is slurry oil used for?
Slurry oil is a heavy aromatic by-product of a refinery’s fluid catalytic cracking unit that forms a small part of global fuel oil supply. Generally, it is mixed into heavy fuel oil as a viscosity cutter. Slurry oil’s low API gravity, however, limits how much can be blended.
What is LCO refinery?
Light Cycle Oil (LCO) is a diesel boiling range product from Fluid Catalytic Cracking Units (FCCUs). However, LCO is a poor diesel fuel blending component without further processing. Oil refining is an industrial process which involves separation, conversion and finishing.
What is light cycle oil?
Light cycle oil (LCO) is a diesel boiling range product from fluid catalytic cracking units. However, LCO is a poor diesel fuel blending component without further processing.
What is soaker visbreaking?
In soaker visbreaking, the bulk of the cracking reaction occurs not in the furnace but in a drum located after the furnace called the soaker. Here the oil is held at an elevated temperature for a pre-determined period of time to allow cracking to occur before being quenched. The oil then passes to a fractionator.
What is coking and visbreaking?
Coking is a process for thermally cracking large molecules in residual oil feeds from atmospheric or vacuum distillation columns into shorter-chain lower-boiling molecules, leaving behind the excess carbon in the form of petroleum coke. Visbreaking is a mild form of thermal cracking.
What is decanted oil?
Recommended use : Decant oil is a high-boiling cat cracked aromatic process oil used in the manufacture of carbon black, burning fuel or in the blending of heavy fuel oils (bunker fuel oil).
What is clarified oil?
A complex combination of hydrocarbons produced as the residual fraction from distillation of the products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly greater than C20 and boiling above approximately 350°C (662°F).
Is LCO diesel?
What is Russian light cycle oil?
Russian Light Cycle Crude Oil Light Cycle Oil (LCO) is a diesel boiling range product from Fluid Catalytic Cracking Units (FCCUs). FCCU is responsible for the production of petrol, LPG and Light Cycle Oil (LCO). It can be used in susch industries as Agrochemical, Crude Oil, Petrochemicals, Petroleum Products.
What does cutter stock mean in fuel oil blending?
Cutter stock. Also known as: Cutter. Cutter stock is any stream that is blended to reduce the viscosity of the resulting blend. Cutter stock is commonly used in fuel oil blending.
Which is more valuable LCO or kerosene cutter stock?
Common cutter stocks for fuel oil blending are LCO and kerosene. These cutter stocks are significantly more valuable than the resulting fuel oil blend, so this loss of value translates into a significant cost of meeting the viscosity specification of the fuel oil.
Which is the heaviest product in a refinery?
On the right hand side, the major refinery products going from the lightest to the heaviest. Starting with gasoline, jet fuel and kerosene, heating and diesel fuels, industrial fuel oil, waxes, lubricating oils, greases, asphalt, and petroleum coke would be the heaviest product, which will be a solid obtained from a refinery.
What are the finishing processes in a refinery?
Finishing processes involve hydrotreating to remove heteroatoms (S, N, and metals) and product blending to produce fuels and materials with desired specifications and in compliance with environmental and government regulations.
