  • 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 ...

  • Dynawave® reverse jet scrubber

    How a reverse jet wet gas scrubber works. The DynaWave® Reverse Jet Scrubber is an open duct in which scrubbing liquid is injected, through a non-restrictive reverse jet nozzle, counter current to the dirty inlet gas. Liquid collides with down-coming gas to create the “Froth Zone,” a region of extreme turbulence with a high rate of mass transfer. The clean, water saturated gas continues through the scrubber vessel to mist removal devices. the liquid reverses ...

  • Making the invisible visible

    In FCC Units (Fluidised Catalyst Cracking Units) the atmospheric residue from the distillation is cracked to LPG, naptha and other components. This sometimes leads to “invisible” deposits inside the Riser. This article features Tracerco’s ThruVision™ scans to illustrate how the technology helped the refinery to identify these deposits at an early stage. Bayernoil operates two FCC Units to convert heavy hydrocarbons. In the FCC Unit the feed is injected ...

  • Maximize reliability in grassroots crude units

    Crude unit operators are far too familiar with a long list of crude unit reliability problems including fouling in heat exchangers and fired heaters, poor desalting, corrosion of piping and equipment, and coking in the vacuum column wash zone. Many millions of dollars have been spent fighting these problems, yet they continue to force unplanned shutdowns with depressing regularity. Revamps must address reliability issues, but project scope is hindered by the limitations of existing ...

  • MD FCC Catalysts - boosting middle distillates production in FCC

    Maximizing middle distillates in FCC units. A range of catalysts is available from Albemarle for increasing the production of middle distillates in the FCC process while retaining the many other attractive features of this versatile bottom-ofthe- barrel upgrading process. The key to success is to adjust the catalyst properties for maximum production of LCO while maintaining maximum bottoms (slurry oil) destruction and good product quality. The middle distillate catalyst family ...

Using new measurement detector technology and innovative analysis of gamma scanning data Tracerco is now able to ...

  • 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 ...

  • Opportunity or Annoyance?

    Price differentials between conventional and opportunity crudes compel refiners to process increasing percentages of lower valued opportunity crude. However, as many refiners have learned the hard way, opportunity crudes are tied to unique processing challenges. Furthermore, existing crude unit configurations may limit high profit opportunity crude to a disappointingly small proportion of the total unit blend. Processing a changing slate of opportunity crudes of varying compositions ...
