Hydrocracking
Consider new technologies to raise diesel yield in bottom-of-barrel products
The debate continues over adding a new delayed coker vs. a residue hydrocracker upstream of an existing delayed coker.
Update hydrocracking reactor controls for improved reliability
The industry consultant believes auto-quench, excursion control and bed-outlet layers should join auto-depressure as industry-best practice for all hydrocrackers.
Maximize diesel production in an FCC-centered refinery, Part 2
Part two of this series focuses on the selection of FCC catalysts, methods for hydroprocessing light cycle oil (LCO) and the production of diesel fuel from FCC byproducts.
Maximize diesel production in an FCC-centered refinery, Part 1
For refineries with an FCC unit as the main conversion vehicle, the debate is how existing refinery assets can best be used to economically increase diesel production.
Redefining reforming catalyst performance: High selectivity and stability
Highly developed CCR catalysts are more robust to ensure extended service over 7–9 years.
Upgrade heavy oil more cost-efficiently
A new technology can economically upgrade and significantly improve the properties of heavy oil by reducing viscosity, increasing gravity and removing contaminants.
Increase FCC processing flexibility by improved catalyst recycling methods
The dynamic global refining market emphasizes the need for greater operating flexibility in the fluid catalytic cracking (FCC) unit.
HP Construction Profile: Texas-based refinery has a long history
The Valero Port Arthur Refinery was commissioned in 1901 and has had many process additions and improvements throughout its history (see pg. 38). In 2001, nearly $850 million was invested in a delayed..
HP Insight: How long is an economic cycle for the HPI?
As summer takes hold in the Northern Hemisphere, demand for energy in various forms increases. In looking back over the past 90 years, energy demand and pricing cycle through high and low points. In 2..
Largest hydrocracker in China
Refiners are leveraging hydrocracking to respond to momentum in global dieselization, with crude prices forcing refiners to process distressed crudes and difficult feedstock.
