  • Avoid unnecessary costs by understanding process problems before taking action

    When a piece of process equipment starts experiencing problems and producing off-spec product, every engineer’s reaction is to make a change to “fix” the problem and get it back on-spec. yet, many plants lack adequate instrumentation to completely diagnose the cause of the poor performance. Without a more complete understanding of the root cause of the problem, “corrective action” could have little effect or make the problem worse. Gathering supplemental ...

  • Cyanide corrosion causes costly upsets

    Refinery cyanides cause considerable corrosion, hydrogen blistering and waste water treatment problems. The majority of refinery cyanides are formed in the reactor of fluid catalytic cracking (FCC) units. All of the gas from the reactor, including the cyanide, is carried overhead into the distillation column, where water is injected into the overhead stream to control corrosion problems. The resulting sour water is separated from the hydrocarbon products at various stages in ...

  • Tray designs for extreme fouling applications

    Today refiners experience a lot of problems with processing of opportunity or heavy crudes. Such crudes have very high sulfur content and require the addition of amine scavengers before desalting. These amines decompose in the heater and create ammonium chlorides in the presence of water in the top of the crude tower. Dissolved salts start to precipitate and crystallize when the solution becomes saturated and water is vaporized. Such fouling starts to grow below and above trays ...

  • Why do many crude/vacuum units perform poorly?

    In many cases it’s because the original design was based more on virtual than actual reality. There is no question: computer simulations have a key role to play but it’s equally true that process design needs to be based on what works in the field and not on the ideals of the process simulator. Nor should the designer simply base the equipment selection on vendor-stated performance. The design engineer needs to have actual refinery process engineering experience, not ...
