Brazil to raise gasoline, diesel prices by 5%
Petrobras sells gasoline at about a 30% discount to international benchmark prices, with the government reluctant to authorize higher prices for fear of stoking inflation. The subsidized fuel sales have caused steep losses in Petrobras's refining division, thus raising concerns over investment plans.
Case history: Optimization of FCCU with multivariate statistical modeling
Process models and simulation methods can be used to simulate the fluidized-bed catalytic cracking unit (FCCU) process.a,b Likewise, kinetic or multivariate statistical models have been used. Rigorous..
Processing shale oils in FCC: Challenges and opportunities
Detailed feed analysis and cracking studies aid refiners in understanding how best to optimize operations and maximize FCC value when processing shale oils.
Reduce salt corrosion rates with stronger base amines
When processing discounted crude oils, one of the primary challenges refiners face is under-salt corrosion in crude unit distillation overhead systems.
Mitigate fouling in crude unit overhead—Part 1
In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..
Catalyst systems offer flexibility for hydroprocessing applications
Refinersa re strongly motivated to evaluate and select premier catalyst systems for the production of both diesel products from their hydrocracking and diesel treating units.
Improved oxidation process increases sulfur recovery with Claus unit
Since its development in 1936, the “modified Claus” technology has been the preferred process used by refineries and gas processing plants for the recovery of sulfur from acid-gas streams. M..
Update: Russia’s capacity and modernization program
Since 2008, Russian regulations regarding the crude oil and refining industry have changed substantially. At present, Russia has 22 large refineries, each with an individual throughput capacity exceed..
Consider accurate feed characterization with improved simulation methods
Assay definition is crucial for accurate process simulations. The performance of process simulators depends on the feed definition to the processing unit. Modern analytical laboratories can offer comp..
Optimize slop-wax bed height in the vacuum unit
The vacuum distillation (VD) unit in the petroleum refinery separates the heavier fraction of crude oil from the atmospheric distillation unit (ADU) into light vacuum gasoil (LVGO) and heavy VGO (HVGO..
