  • 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 ...

  • Comparing physical solvents for acid gas removal

    Physical solvents such as DEPG, NMP, Methanol, and Propylene Carbonate are often used to treat sour gas. These physical solvents differ from chemical solvents such as ethanolamines and hot potassium carbonate in a number of ways. The regeneration of chemical solvents is achieved by the application of heat whereas physical solvents can often be stripped of impurities by simply reducing the pressure. Physical solvents tend to be favored over chemical solvents when the concentration ...

  • Condensate is crude

    Ultra-light crudes and condensates are here to stay. These streams have flooded the market in recent years, and many of them are deeply discounted against reference crudes. Refiners have been processing increasing percentages of this light material through their Crude Distillation Units (CDUs) up against unit naphtha handling limits. On the surface, processing condensate and other ultra-light crudes with high API gravity and low sulfur should be easy. In reality, many refiners ...

  • 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, ...

  • Eliminate heat exchanger fouling with Watlow’s HELIMAX technology

    Fluctuations within the heat exchanger to either the operating temperature or the mass flow rate are common causes of coking, which can lead to system failures and expensive downtime. Some heat exchanger design methods, like segmental baffles, have known dead zones where hot spots can occur, accelerating the coking process. Watlow’s HELIMAX ultra-efficient heat exchanger was designed to eliminate temperature-related failures. Leveraging our proven, patent-pending continuous ...

  • Is pinch enough?

    Back in the late 1970’s and early 1980’s when fuel gas prices were high, energy utilization assumed major importance. A new method of calculating heat exchanger networks was developed. It was called Pinch Technology. Today pinch has been rediscovered by engineers who have access to fast computer simulation models. But as occurs with any older method that is rediscovered by a newer generation, enthusiasm generated by the rediscovery tends to obscure the deficiencies ...

  • 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.

  • 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 ...

  • 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.
