  • 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 ...

  • 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 ...

  • Hydrogen fuel conversion in fired equipment

    Organizations are facing unprecedented challenges in achieving their strategic climate goals. Now is the time to evaluate options for hydrogen refuelling, efficiency improvements, and novel methods of CO2 reduction in fired heaters and boilers. You can reduce carbon footprints by refuelling fired equipment with hydrogen or ammonia. When planning a refuelling effort there is much more to consider than just the Wobbe Index and combustion performance. The system will experience ...

  • 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 ...

  • Moving gamma scanning forward – quantitative analysis of tray capacity

    Improving process operating margins can include maximising production of higher value products and/or minimising production costs. Process plants depend heavily on fractionation towers to produce products meeting customer specifications. Tower gamma scanning is well established in the process industries as a qualitative tool to help troubleshoot fractionation towers. 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 ...

  • On-line heater and boiler chemical cleaning technology

    GTC’s fired heater cleaning solves common process feed heater problems. With rising pressure to reduce energy costs, GTC’s advanced fired heater/boiler chemical cleaning technology is an effective way to improve heater efficiency without shutting down plant operations. Our technology is designed to quickly remove deposits such as slag and other fouling materials that build up over time on tube fire side surfaces. Fouling in the convection section caused by condensed ...

  • 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 ...

  • PackView™ - quantitative analysis of packing mal-distribution

    The last issue of Tracerco Insight (Vol 6 Ed 1) featured our patent pending FrothView™ technology illustrating how using Tracerco’s new measurement detector technology and analysis of gamma scan data provides quantitative information about the useful capacity of trayed towers. In this article you will learn how applying this technology to packed towers can determine the % liquid fraction providing a measure of the maximum useful capacity of the packing. Enhanced ...

  • Xtend by XRG - A better technology for heat transfer

    Fired Heater Fouling Costs Millions. A typical 100,000 barrel per day refinery loses $3-7 million annually because of fouling in fired heaters. Fouling overheats tubes, increases firing rate, reduces yields, and causes lost onstream days. Shutting down a crude, vacuum, or coker heater is extremely costly both in labor and throughput. To combat these issues, XRG Technologies developed Xtend - a tube-insert to reduce fouling and increase heat transfer. Xtend - A Better Technology ...
