What is fluid catalytic cracking process?

Unlike atmospheric distillation and vacuum distillation, which are physical separation processes, fluid catalytic cracking is a chemical process that uses a catalyst to create new, smaller molecules from larger molecules to make gasoline and distillate fuels.

How does a FCCU unit 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 RFCC unit in refinery?

Residue fluid catalytic cracking (RFCC) is used for upgrading heavy feedstocks to light products such as gasoline.

Why fluid catalytic cracking is important?

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.

Why is catalytic cracking useful?

Catalytic cracking is an important process in the oil industry where petroleum vapor passes through a low-density bed of catalyst, which causes the heavier fractions to ‘crack’ producing lighter more valuable products. In the petrochemicals industry they are used for producing polyolefins on a very large scale.

What is the difference between thermal cracking and catalytic cracking?

Thermal Cracking: Thermal cracking is the process of breaking down large compounds into small compounds at high temperatures and high pressures. Catalytic Cracking: Catalytic cracking is the breakdown of large compounds into small hydrocarbons using an acid catalyst.

What is importance of FCC Rfcc & hydrocracker unit in a refinery in BS VI scenario?

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.

What does Rfcc stand for?

How do cracking units work?

Steam cracking Steam cracker units are facilities in which a feedstock such as naphtha, liquefied petroleum gas (LPG), ethane, propane or butane is thermally cracked through the use of steam in a bank of pyrolysis furnaces to produce lighter hydrocarbons.

What is the role of fluid catalytic cracking in petroleum industry?
