  • Anti-fouling trays maximize coker main fractionator profitability

    The Coker Main Fractionator is systematically subjected to harsh operating conditions that can lead to deteriorating efficiency and performance due to coking and fouling. Poor reliability results in loss of profitable coking margins for the refinery. The main fractionator vapor feed from the coke drum overhead is characterized by a tendency for further cracking, as well as the presence of fine coke particles carried from the drums. The hottest zones of the column (bottom quench, ...

  • Auto-switch boring / cutting tool

    The innovative DeltaValve auto-switch coke cutting tool provides a high level of safety and reliability during de-coking operations by allowing the tool to remain in the drum during switching between boring/cutting modes. The auto-switch tool, in combination with the DeltaValve drill stem guide enclosure and the top unheading valve, provide maximum coker safety by allowing personnel to be removed from the cutting deck. Flow channels in the auto-switch tool are optimized to ...

  • 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 ...

  • 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 ...

  • Bicine can be controlled

    Bicine is a very corrosive degradation product produced in certain DEA and MDEA systems. Amine system operators must take steps to minimize O2 and SO2 incursion into the amine system and will need to monitor Heat Stable Salts and Amino Acids (Bicine) concentrations in the amine.

  • Cyanide corrosion causes costly upsets

    Refinery cyanides cause considerable corrosion, hydrogen blistering and waste water treatment problems. The majority of refinery cyanides are formed in the reactor of fluid catalytic cracking (FCC) units. All of the gas from the reactor, including the cyanide, is carried overhead into the distillation column, where water is injected into the overhead stream to control corrosion problems. The resulting sour water is separated from the hydrocarbon products at various stages in ...

  • DeltaValve retractable center feed injection device

    The introduction of DeltaValve’s fully automated coke drum unheading valve in 2001 necessitated the development of side feed entry into the coke drum. No longer was it possible to feed resid into the coke drum through the bottom  ange as was standard with traditional manual or semi-automated unheading systems. Over the years, various styles of side feed entry technology emerged: single inlet, dual inlet, and others, some with straight feed lines, or angled/curved ...

  • 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 ...

  • Minimize recycle and coke carryover with the coker main fractionator washspray header design

    Coker Main Fractionator flash zone design is critical to reliable operation of the column and maintaining product quality. This section commonly experiences problems related to the presence of unstable heavy liquid and carryover of solids. Successful operation often hinges on the design of the wash liquid distributor. Although Sulzer utilizes several styles of wash liquid distributors, this bulletin focuses on the spray header design. The spray distributor design is a careful ...

  • 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 ...

  • On budget, on time, offine

    Flawless project execution will not prevent a unit shutdown due to selecting the wrong metallurgy for a challenging crude slate. No matter how well it is fabricated and installed, a shell and tube exchanger with cold, high viscosity vacuum resid on the tube side will have poor heat transfer performance. On-time shipping and installation of a too-small desalter will not prevent crude column overhead corrosion if the centerline velocity is overly optimistic for the design crude. A ...

  • 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 ...

  • Removal of foaming

    In a recent case history, an East Coast Refinery was experiencing frequent upsets in their amine system due to foaming. MPR Services was contacted and brought in their SigmaPure™ System. SigmaPure removed the foaming agents and the unit returned to optimal operations. Operations management and Engineering were very pleased and the refinery gas treating system significantly increased performance completely eliminating upsets and reducing amine purchases.

  • Running dirty amine to save costs

    Some plants have saved money in the short term by running dirty amine/glycol systems. The result of this obfuscation strategy often is problematic operations. Problems resulting from corrosion, foaming and loss of acid gas absorption arise from processing with contaminated amine/glycol. A single severe process upset resulting in a large solvent loss may put you over budget for the year. We know how important controlling amine/glycol losses and costs can be. MPR Services, Inc. ...
