Advanced hydrocracking unit flow scheme optimization and integration approach to maximize refinery margins for a residue upgrading project
The integration of a solvent deasphalting and hydrocracking upgrading complex provides a favorable techno-economic return for residue upgradation at relatively lower capital expenditures vs. other alternatives for a brownfield project.
Catalyst replacement strategy for a hydrocracking unit at a Middle East refinery
A Saudi Aramco refinery operates a series-flow, single-stage hydrocracking unit (HU) in a recycle high-conversion mode. The HU has been in operation for over 35 years and is being debottlenecked to increase its throughput by 20%.
Decrease tube metal temperature in vacuum heaters
Various options for reducing the TMT of a vacuum heater, such as changing the transfer line size and adding extra surface area in the radiation and convection sections, are examined here. The best option generally depends on the limitations under which the heater operates with regard to the process requirements and the downstream equipment limitations and flexibility.
Troubleshoot and optimize debutanizer columns in hydrocrackers
Saudi Aramco’s Riyadh refinery operates a series-flow, single-stage hydrocracking unit (HCU) in recycle high-conversion mode. The unit underwent a revamp in 1983 and presently processes a mixture..
