Special Report: Process/Plant Optimization
Using a rigorous refinery-wide simulation, a refiner moved more low-value products into value-added end products
Using this technique can take the guess work out of design calculations and improve costs
Incorporating them can yield significant improvements in efficiency and productivity
A European refiner effectively uses delayed coking to exit residual fuel-oil market
Cutting corners can incur long-term performance issues and expenses; this refiner used revamp monies wisely to stretch capacity and increase equipment availability
Common-sense approach uncovers potential problems when upgrading tower internals
Understanding the stages and having a strong vision of where you need to go are essential first steps
Asset Management
Four key benefits can evolve from filing the paperwork
Corrosion/Maintenance
Several inspection techniques were required to determine the root cause of the failure
Engineering Case Histories
Weld failures can be due to manufacturing defects
