  • A single integrated vacuum system

    Failure to design the vacuum unit as an integrated system will invariably result in unsatisfactory yield and poor product quality (high vanadium, nickel, microcarbon, or asphaltenes), and ultimately, an unscheduled shutdown. To avoid these revamp problems the charge pump, fired heater, transfer line, column internals and ejector system must all be evaluated and designed as a unified whole so that critical variables – heater outlet temperature, coil steam injection rate, ...

  • 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 ...

  • Be smart about FCC olefin recovery

    Whether the driver is propylene as a chemicals feedstock or propylene and butylene as alky feed, FCC units worldwide are being pushed to maximize olefin production. Increased hydrotreating to meet Tier 3 gasoline requirements is reducing gasoline pool octane at a time of high premium-to-regular gasoline price differentials. Maximizing FCC olefi ns to produce high octane alkylate barrels is attractive – if they can be recovered in the FCC gas plant LPG stream. Higher reactor ...

  • Beyond the column: Sulzer ESR

    New bypass line between diesel draw-off line to side stripper, new bypass valve, incl. update of P&ID, piping isometrics and pipe

  • Caustic tower revamp

    A customer contacted Sulzer to increase capacity while improving the CO2 removal in the existing CO2 absorption column of their ethylene plant. This was the third revamp for this particular column and continued improvements can be hard to find. A proper caustic tower design requires a proper understanding of CO2 absorption with caustic. CO2 + 2NaOH Na2CO3 + H2O Sulzer replaced the conventional random packing with NeXRing and modified the operating parameters to match the ...

  • CO2 reduction in fried equipment

    Fired heaters emit millions of tons of carbon dioxide (CO2) every year. Fired heaters usually have a fuel efficiency well below 100%, so any improvements that making them more efficient reduces CO2. Heaters are currently fuelled by carbon-bearing refinery fuel gas or natural gas, so further CO2 reduction is possible by changing to fuels with less carbon content. With the ever-changing regulatory climate, enacting an emissions reduction plan can provide a strategic advantage ...

Equipment nearing the end of its operational life can not only put plants at risk of ...

  • The case for plant modernization and upgrades

    With a system that's outdated or showing signs of it, you are well aware of the risks of running your plant processes with aging hardware and software. Waiting to modernize will impact your cost of ownership due to shortages of critical parts and support, will increase risk of an unplanned production shutdown, and likely will have no incremental benefits. A well-designed modernization approach allows the opportunity to reduce system footprint and costs. Whether by eliminating ...
