Responsibilities of a Good HAZOP Team Leader

A HAZOP team facilitator is a key person in conducting a successful and effective hazard and operability (HAZOP) study. A HAZOP team facilitator is responsible for leading and managing the

Guidelines for Nodes Selection in HAZOP Study

A node is a discrete part of the process or system that has a defined function with definite boundaries and is selected for analysis in the HAZOP study. Generally, they

HAZOP Study Procedure

A HAZOP study is undertaken by the application of formal, systematic, and critical examination of the process and engineering intentions of the process design. The potential for hazards or operability

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 Hazard 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
