Asia’s new LNG plants may boost regional demand
The startup of new LNG import facilities in China, Singapore, Malaysia and South Korea may provide a boost for Asian spot prices during the final months of 2013, according to a report.
Asia refining margins remain weak on low demand
Margins are being pressured by simultaneous weakness across the barrel, with gasoline, gasoil and fuel oil cracks all deteriorating recently. The Singapore refining margin fell to its lowest level since late 2011.
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.
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..
Use modeling to evaluate processing solutions for heavy oils
To optimize processing and reduce design and operating costs, refiners should consider using accurate simulation models that are specifically tailored for heavy crudes.
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..
Evaluate surfactants as antifoam substitutes in amine systems
The handling capacity of gas sweetening plants using amine solutions is greatly affected by foaming problems. To mitigate foaming problems, antifoam is injected into the amine recirculating system at Oil and Natural Gas Corp.'s Uran refinery in India.
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..
