What is CCR unit?
Continuous Catalytic reforming (CCR) is a chemical process that converts petroleum refinery naphthas distilled from low-octane oil into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline.
What is an FCC unit?
An FCC unit is a fluid catalytic cracking unit, which is a type of process that is used in refining crude oil into gasoline. The expansion joints used for the service are called stand pipe expansion joints.
What is an FCC in a refinery?
Fluid catalytic cracking (FCC), a type of secondary unit operation, is primarily used in producing additional gasoline in the refining process.
What catalyst is used in FCC?
A modern FCC catalyst has four major components: crystalline zeolite, matrix, binder, and filler. Zeolite is the active component and can comprise from about 15% to 50%, by weight, of the catalyst. Faujasite (aka Type Y) is the zeolite used in FCC units.
What is a CCR process?
Continuous catalyst regeneration (CCR) is part of the catalytic reforming process in a refinery where hydrogen and naphtha feed are reacted to create desired end products. The catalyst used in the reaction is continuously flowing through the reactors and then regenerated.
What is refinery catalyst?
In the refining industry, catalysts are used to convert heavy oil into valuable, distillable products. They can be regenerated and used with a wide range of feedstocks to bring improved performance to refineries around the world.
What is FCC process?
Fluid catalytic cracking (FCC) process is an important oil refinery process, since this process converts heavy petroleum fractions into lighter hydrocarbon products inside a reactor. In an attempt to maximize production and improve operating efficiency, a comprehensive analysis of a FCC unit regenerator has increased.
What is a catalytic cracking unit?
Also known as a Cat Cracker, the Fluid Catalytic Cracking Unit (FCCU) is a piece of refining equipment used to convert the heavy portion of crude oil feedstock into lighter petroleum products, including liquified petroleum gas and gasoline.
What is importance of FCC and hydrocracker unit in a refinery?
In a refinery, the hydrocracker upgrades VGO through cracking while injecting hydrogen. This yields a high volume of high-quality diesel and kerosene product. This is in contrast to the FCC, which uses the same feed (VGO) but produces more and better-quality gasoline.
How does CCR reactor work?
What is the difference between FCC and RFCC?
RFCC is an extension of conventional FCC technology, offering better selectivity to produce higher amounts of gasoline and less gas than hydro and thermal processes.
What is the difference between FCC and RFCC in a refinery?
Process description RFCC is an extension of conventional FCC technology, offering better selectivity to produce higher amounts of gasoline and less gas than hydro and thermal processes.
How does an FCC reactor work?
In the FCC unit, heavy hydrocarbons from crude oil are broken or cracked into smaller hydrocarbons, which can then be processed into gasoline and other fuel products. The heavy hydrocarbons are first fed into a reactor where they mix with a catalyst.
What is platforming in refinery?
Refinery platforming processes a feedstock of heavy naptha, a crude oil distillate fraction with boiling point 100 to 160oC comprising mainly straight chain alkenes that are combined with hydrogen rich re-cycle gas, in a two phase liquid/vapour mixture which is heated to be wholly vaporous.
What is importance of FCC Rfcc & hydrocracker unit in a refinery in BS VI scenario?
What is cat feed in refinery?
Also known as: fluid catalytic cracker, cat cracker, cat unit, FCCU, CCU, Houdry. In refining, the FCC is the most common unit used to upgrade heavier distillation cuts to light products. The FCC takes VGO and similar intermediate streams and cracks them using heat in the presence of a catalyst.
