  • 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 ...

  • 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 ...

  • Customized grading solutions for your feedstock

    Match your catalyst grading to your feedstock for minimum pressure drop build-up and maximum demetallization. As today’s opportunity crudes and heavier feedstocks become more economically viable, the oil fractions you refine are posing new challenges. Creating the optimal grading solution for your individual feedstock is essential to minimize pressure drop build-up, increase metals pick-up, and reduce downtime and catalyst replacement. An overlooked advantage The importance ...

  • 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, ...

  • Diagnostics™ Leak Study Optimise Ammonia Synthesis Loop

Tracerco Diagnostics™ Leak studies have proven invaluable in identifying potential areas or locations of leakage within an ammonia synthesis processing loop, converter, ...

  • 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 ...

  • Expertise beyond the column LPG Treating

    DC Coalescer™. Composite two-material design with very different surface free energies — typically metal and plastic. This simple principle offers notable advantages over conventional, single medium alternatives. The combination of both high and low surface energies gives effective separation irrespective of which phase is dispersed. The rate of coalescence is significantly increased.

  • FCC Main Fractionator Coking

    One common cause for coking is poor vapor distribution. Packing selection in the Slurry P/A section is critical to ensure good distribution and reliable performance. Mellagrid™ combines the performance of Mellapak™ with the robustness of traditional grid. Resists coking and fouling due to its smooth surface and geometrical. Better de-entrainment and separation efficiency than traditional grid. Efficient dissipation of temperature. Excellent mechanical strength.

  • Gain 5-10% efficiency with this simple 4-pass tray revamp

    The design of 4-pass trays can be complex. It not only requires a close evaluation of the mechanical design but also the process response to that design at various flow rates. The balancing of the fluid flows across the tray can have a substantial effect on the tray performance, namely efficiency. Many existing columns are operating with older 4-pass designs. While some of these are well designed, others could use some improvement. Since 4-pass trays always involve a fairly ...

  • Improve separation in your column by increasing the number of trays

    Refiners often face revamp challenges when trying to improve separation within an existing column. Improving diesel recovery from gas oil, splitting benzene precursors from naphtha reformer charge, or simply minimizing product overlaps after capacity creep can all be difficult when limited by a fi xed existing tower height. For these cases, revamp solutions that increase the number of theoretical stages by adding trays to an existing column or a section of a column pay large dividends. ...

  • Increase capacity in your column with a tray design revamp

    When trying to increase column capacity beyond design rates, an operator may notice loss in separation efficiency or high pressure drop, indicative of either vapor phase or liquid phase hydraulic limitations. An optimized tray design can eliminate hydraulic constraints to provide better column capacity and performance. Common Vapor Constraints to Raising Throughput In systems limited by higher vapor rates (typically lower pressure systems), jet flooding may constrain the column. ...

  • Preparing for a petrochemical plant revamp or technology upgrade

    Petrochemical producers have recently confronted unprecedented volatility in crude oil prices and limits on advantaged feedstock, while the refining and gas sectors remain vigilant to global supply conditions. However, some industry challenges remain unchanged, such as the need to optimize plant operations and cut carbon footprint by reducing the amount of energy required to drive a plant. 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 ...
