Coke drum and blowdown system overpressure protection design - Part 1
The blowdown (BD) system in delayed coking units (DCUs) receives waste streams generated during the coke drum (CD) decoking process to recover valuable hydrocarbons and water. In recent DCU designs, the CD pressure relief valves (PRVs) also discharge to this system and then to the flare system via the BD PRVs.
FCC operational changes to boost gasoline octane
The fluid catalytic cracking unit (FCCU) is one of the main units providing gasoline with high-octane numbers to the refinery gasoline pool.
Ultra-deep desulfurization of FCC gasoline: Reactive adsorption strategy
With an increase in concern for the environment, countries around the world are implementing stringent environmental regulations and are continuously pressuring refiners to reduce the amount of sulfur in transportation fuels—primarily gasoline and diesel—to combat airborne pollution caused by vehicles.
Digital: Digitalization—Why now?
The process industries are under threat.
Petrochemicals: Which network can fulfil the petrochemical sector’s desire to exploit Industry 4.0?
The global petrochemical industry has not been short of success.
The critical maintenance team: Do you have one?
Larger plants typically have planners and maintenance supervisors onsite, as well as operations personnel.
Application of ring-type joint gaskets in a refinery
In refineries and petrochemical plants, ring-type joint (RTJ) flanges have been applied to high-pressure processes or sensitive areas that are susceptible to leaks.
Fabrication of clad equipment and piping—Part 2
For pressure vessels, heat exchangers and piping in corrosive services, the materials in contact with the process are often required to be high alloys to provide a reliable service life.
Design considerations for rigging and transportation of large process columns
Design guidelines for rigging and transporting large process columns are outlined in this article, along with the various aspects that should be considered during the initial design phase of equipment.
The top three causes of contractor and engineering misalignment
When contractors, engineers and operations teams at downstream processing plants do not work together at optimal efficiency, it can present serious problems.
