Which type of feed is treated in hydrocracker?

In a two-stage hydrocracker, a mixture of hydrocarbon feed and hydrogen is heated and injected into a reactor vessel containing a hydrotreating catalyst. This catalyst accelerates the reactions that remove sulfur and nitrogen from the hydrocarbon and open up and saturate aromatics rings.

What is hydrocracker feed?

A hydrocracking unit, or hydrocracker, takes gas oil, which is heavier and has a higher boiling range than distillate fuel oil, and cracks the heavy molecules into distillate and gasoline in the presence of hydrogen and a catalyst. …

What is hydrocracker unit?

Hydrocracking Units, also known as Hydrocrackers, are types of process equipment used in petroleum refining. Hydrocrackers use hydrogen and a catalyst to break down heavy crude oil molecules into various distillates and gasoline.

What’s the difference between hydrotreating and hydrocracking?

The key difference between hydrocracking and hydrotreating is that hydrocracking includes the conversion of high boiling constituents into low boiling constituents, whereas hydrotreating includes the removal of oxygen and other heteroatoms. Hydrocracking and hydrotreating are useful processes in petroleum oil refining.

How is hydrocracking used in the oil industry?

• Hydrocracking converts low value feeds to high value transportation fuels and petrochemical feedstock • Adds hydrogen which increases the volume of the products • Converts heavy gas oils to clean jet and diesel, UOP’s History of Hydrocracking Progress

Why is hydrocracker an important source of diesel?

Hydrocracking is an important source of diesel and jet fuel. A refinery’s ability to upgrade low-value products into high-value products and convert high-sulfur material to low-sulfur material with a secondary unit like a hydrocracker plays a key role in determining its economic fate.

What kind of fuel oil is used in a hydrocracker base oil unit?

A quick estimate using the SRT-VII heater from Lummus Technology indicates an ethylene yield of 32 wt% and a propylene yield of 14 wt% for this feed, with less than 9 wt% pyrolysis fuel oil. The balance UCO fulfills the FCC unit’s feed requirement.

What can be hydrocrackered to make jet fuel?

Coker gasoil – This VGO-range product from the coker is well suited to a hydrocracker, which is better able to handle its unsaturated components than an FCC unit is Cycle oils and cracked distillates – These low-quality diesel-range streams can be hydrocracked to make jet fuel and gasoline-range material
