Slurry Phase Hydrocracking Process
A slurry phase reactor (SPR) is used in petroleum refineries for the hydroprocessing of feeds with very high metal content to obtain lower-boiling products. This technology adopts severe operating conditions...

History of Hydroprocessing
Hydrotreating and Hydrocracking are among the oldest catalytic processes used in petroleum refining. They were originally employed by I.G Farben in Germany in 1927 for converting lignite to gasoline and...

Hydroprocessing in Petroleum Refineries
In petroleum refineries, hydroprocessing is a catalytic process in the presence of Hydrogen to stabilize petroleum products, remove objectionable elements from feedstocks, and crack heavy hydrocarbons into useful lighter products....

Types of Corrosion and Controls in Hydroprocessing Units
The operating conditions of Hydroprocessing units make them vulnerable to various corrosion phenomena. The severity of the hydroprocessing units in petroleum refineries has increased due to higher levels of sulfur...

Troubleshooting of Feed Filters in Hydroprocessing Units
In Hydroprocessing units the feed filtration system removes solid particles and contaminants from the feedstock before it enters the hydroprocessing reactor. It is important to remove the particulates from the...
