  • Avoid fired heater coking

    For many refiners, heater coking in Crude and Vacuum Distillation Units (CDU/VDUs) is a common occurrence. Many units around the world are shut down every two years, every year, or even every six months to deal with chronic heater coking. However, with the right design features driven by a solid understanding of heater coking mechanisms, fired heater run length can be extended beyond five years, even with relatively challenging crudes. The two primary drivers of heater tube ...

  • 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 ...

  • Designing deepcut vacuum units that really work

    Every barrel of vacuum gas oil (VGO) you can save from being reduced to coke in the delayed coker unit is a barrel more that can go to the FCCU. That’s a good reason to raise HVGO cutpoint. But how to do it? Some people think the job can be done just by running computer models in the engineering office, relying on vendors and their data sheets for a clue to true equipment performance. Experience, however, shows it just ain't so. For either a grass roots project or a revamp, ...

  • Dynawave® reverse jet scrubber

The clean, water saturated gas continues through the scrubber vessel to mist removal devices. the liquid reverses ...

  • Equipment design matters

    Many attractive projects fail to meet expectations at startup. Disappointing performance often results from bad simulation practices and/or poor equipment design rather than faulty execution. Refineries are currently considering FCC revamps to increase olefins for more alky unit feed, maximize LCO product recovery, and minimize slurry product by producing HCO for hydrocracker feed. These changes raise fractionator operating temperature. Higher temperatures require better process ...

  • FCC stripper - distribution studies

  • Myth of the 1000°F vacuum unit cutpoint

    Canadian Synbit and Dilbit crudes will come to make-up a substantial fraction of feedstocks to North American refineries. Today, however, for the most part refiners both north and south of the 40° parallel seem to be unaware of the extreme challenges this change will present. To run an oil sands crude in a vacuum unit designed for conventional heavy feedstocks and to expect a 1000°F cutpoint for a 5-6 year run is like believing in the Tooth Fairy. Bitumen based crudes ...

  • Nasty stuff

    Heavy crudes are here to stay. As longs as oil prices remain high, Canadian, Venezuelan, Deep Water Gulf of Mexico, Mexican and other low API gravity crude oils will play an ever more important role in supplying world refineries. And prices promise to remain high because gainsayers notwithstanding, Hubbert was right. A big question is how to handle best these nasty crudes? Do you revamp existing units or invest in new capacity? With refineries now running flat out, the balance ...

  • Oil sands crude – profits and problems?

    Canadian bitumen production currently runs about 1 MMbpd, with some being sold as Synbit and Dilbit. Over the next 10-12 years output is expected to increase to 3.5 MMbpd and more refiners will begin investing to process it and come to depend on the Synbit and Dilbit for a significant part of their supply. Few today, however, have ever processed these feeds at high blend ratios, and are unaware that conventional process and equipment designs are not up to the job. Canadian oil ...

  • On budget, on time, offine

    Flawless project execution will not prevent a unit shutdown due to selecting the wrong metallurgy for a challenging crude slate. No matter how well it is fabricated and installed, a shell and tube exchanger with cold, high viscosity vacuum resid on the tube side will have poor heat transfer performance. On-time shipping and installation of a too-small desalter will not prevent crude column overhead corrosion if the centerline velocity is overly optimistic for the design crude. A ...

  • Tray design features that reduce turnaround maintenance time

    Column shutdowns can be costly. Production is halted and maintenance expenses accumulate without any offsetting revenue. Maintenance crews need to isolate, open, inspect, modify, repair, and close columns, all under pressure to complete work as expeditiously as possible. Minimization of shutdown costs begins during the equipment design phase. Sulzer incorporates several features into our tray designs that can reduce column shutdown time. Tray Replacement and Installation Tray ...

  • When reliable operation and easy inspection is key

    Topsoe’s outlet collector is easy to install and inspect and help ensure even flow distribution in the bottom of the reactor. It is important to have the best catalyst to ensure optimal performance of your hydroprocessing unit. However, it is equally important to have the best reactor internals to ensure the optimal flow conditions for the catalytic reactions in your reactor. Topsoe’s outlet collector ensures even flow distribution in the bottom bed thereby maximizing ...

  • 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 ...

  • Why produce diesel from the vacuum unit?

    Look ahead five years. The economy is likely to keep tightening and the rush to control pollution will inevitably be accompanied by demands for greater energy conservation. Consequence? A growing market for diesel which yields more energy per unit volume. Yet many continue to believe that producing diesel from the vacuum unit is poor design—that it should be produced only from the atmospheric column. Hence many refiners feed 20-30% diesel boiling range material to their ...

  • Understanding the financial impact of a collapsed flue gas tunnel in your SMR

    The overall influence of tunnels on the flue gas flow in a steam methane reformer has been modeled and documented, and the concept that running a reformer without tunnels can decrease overall efficiency is well understood in the industry. The study detailed in this webinar focuses on the effects of operating a reformer after removing just a single tunnel, leaving the rest in place. The resultant flue gas flow field is analyzed by looking at temperature profiles, residence time ...
