The FCC (Fluid Catalytic Cracking) unit is one of the most important and widely used processes in petroleum refineries. It is used to convert heavy, high-boiling-point hydrocarbons from crude oil into lighter, more valuable products such as gasoline, diesel, propane, ...

The RFCC (Residual Fluid Catalytic Cracking) unit is an advanced refining process that upgrades heavy residues from the crude distillation unit (CDU) into more valuable, lighter products like gasoline, diesel, and petrochemical feedstocks. It is a type of fluid catalytic ...

Sweet Crude refers to crude oil that has a low sulfur content, typically less than 0.5% by weight. The term “sweet” comes from the oil’s relatively pleasant or neutral odor, in contrast to the pungent and foul smell of sour ...

Sour Crude refers to crude oil that contains a relatively high amount of sulfur (usually more than 0.5% by weight). This sulfur content makes it “sour,” as opposed to “sweet” crude, which has lower sulfur content. The sulfur compounds present ...

Vaporization and evaporation are both processes by which a liquid changes into a gas, but they occur under different conditions and have distinct characteristics. Here’s a breakdown of the key differences between the two: Vaporization: Definition: Vaporization is the process by which ...

Vacuum Distillation is a special type of distillation process that is used to separate components of a mixture by lowering the pressure (creating a vacuum) in the distillation system. This process helps to reduce the boiling points of the components, ...

Distillation is a separation process that is used to separate a mixture of liquids or gases into its components based on their different boiling points. It works by heating the mixture to a temperature at which one or more components ...
