HAZOP Study Procedure
HAZOP Study (Hazard and Operability Study) is a structured and systematic technique for identifying potential hazards and operability problems in a process system. It is widely used in industries like
Hazop Study Terminologies
A HAZOP study is a simple and well-structured methodology for hazard identification in process plants. It is an investigation technique that is designed to inspire imaginative thinking (or brainstorming) by
Stages of Hazop Study of Process Plants
For a new project, the greatest benefit is obtained by carrying out several studies throughout the design process. One such sequence is the Hazard Study (HS) methodology developed by ICI
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.
Controlling Overheating Rupture in Hydroprocessing Units
Short Term Overheating Stress rupture is the phenomenon caused by localized overheating well above the design temperatures. It can cause permanent deformation in process equipment. The equipment may result in
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
