  • Air emissions modeling advances for oil and gas production facilities

    A perfect storm has dramatically changed the way oil and gas production facilities are designed and permitted for air quality compliance. Air quality regulations have been strengthened due to rule changes in the Clean Air Act (40 CFR 60, Subpart OOOO), drastically reducing the allowed emissions of VOCs from well sites. These changes were made along with new regulations of Green House Gas emissions (40 CFR 98, Subpart W). Due to the more stringent and complex permitting regime, ...

  • Approaches to simulating distillation and absorption

    Distillation of spirits has been practiced since the time of the ancient Greeks who ascribed sacred powers to the liquids that resulted from refining wine using stills such as the one shown in Figure 1. Dionysian cults incorporated these early spirits into religious rituals. Distillation and other phase separation processes have come a long way since then, and so have the ways they’ve been analyzed and computed. Figure 2 shows the progression of models and computational ...

  • 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 ...

  • 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, ...

  • Dynawave® reverse jet scrubber

    How a reverse jet wet gas scrubber works. The DynaWave® Reverse Jet Scrubber is an open duct in which scrubbing liquid is injected, through a non-restrictive reverse jet nozzle, counter current to the dirty inlet gas. Liquid collides with down-coming gas to create the “Froth Zone,” a region of extreme turbulence with a high rate of mass transfer. The clean, water saturated gas continues through the scrubber vessel to mist removal devices. the liquid reverses ...

  • Ideal stage or mass transfer...which model should be used?

    The design and optimization of separation processes is carried out using process simulators, which utilize various calculation approaches. Two techniques that are widely used for modeling distillation are the ideal stage model and the mass transfer model. Ideal Stage Models - The ideal stage model requires a minimum amount of data—only equilibrium relationships and enthalpy data for the heat balance. The assumptions of the ideal stage approach are: 1) that the vapor and ...

  • InFocus™ Unit Monitoring Tool can be used to avoid costly plant slowdowns

    Challenge: Avoiding slowdowns by detecting process issues early. A cumene customer with an ExxonMobil alkylation/transalkylation catalyst system has been on-stream for over 5 years producing cumene product at high purity and yield. Unit monitoring analysis was provided on a quarterly basis. Shortly after one of the monitoring reviews, the benzene feedstock quality was compromised. The poisons in the benzene feedstock were undetected and caused significant deactivation of the alkylation ...

  • InFocus™ Unit Monitoring Tool can help avoid unplanned shutdows and lost production

    Challenge: Avoiding shutdowns due to lack of experience and poor knowledge transfer A large refinery frequently rotates personnel to give them broader experience. Frequent engineering personnel changes result in sub-optimal knowledge transfer and reduced operational experience of the dewaxing technology. An engineer inexperienced with the operating unit was unaware of a non-standard operating mode which resulted in an unplanned shutdown and three days of lost production. Additional ...

  • InFocus™ Unit Monitoring Tool can provide alerts regarding unit operations

    Challenge: A refinery produces high-quality, Group II base oil using MSDW™ Catalyst. Historically ExxonMobil Technical Support had received process condition data to periodically evaluate unit performance and provide technical recommendations on catalyst aging and unit operations. Recently, an operational upset caused rapid catalyst deactivation and was not identified due to unavailability of data for the ExxonMobil experts. Because the unit is on an annual monitoring cycle, ...

  • InFocus™ Unit Monitoring Tool could have helped avoid up to 40% reduction in catalyst life

    Challenge: Avoiding shutdowns by detecting impact to changes in sulfur specification. A major diesel producer on a 36-month catalyst changeout cycle runs a hydrotreater with a target product sulfur specification of 8 wppm. Typical operation variability routinely leads to over-treating product sulfur by 2 wppm. The diesel producer expects that the over-treating of the diesel hydrotreater product sulfur by 2 wppm has a negligible impact on cycle length, so no objections are raised ...

  • InFocus™ Unit Monitoring Tool enables timely evaluation and detection of unit issues

  • InFocus™ Unit Monitoring Tool facilitates collaboration with ExxonMobil experts

    Challenge: Effective communication and collaboration between companies. Communication between a cumene customer and ExxonMobil Technical Support was challenging due to language and location barriers. Feed treaters which should be regenerated at least once a week were only regenerated once every couple of months. This reduction in regeneration frequency led to faster deactivation of the alkylation catalyst with a potential 20% reduction in cycle length. Solution: InFocus™ ...

  • InFocus™ Unit Monitoring Tool helps maintain process continuity

    Challenge: Maintaining continuity and retaining knowledge A new employee was assigned as the process engineer for the cumene unit of an ExxonMobil customer. Unfamiliarity with process and systems created a 6 month gap in providing data to ExxonMobil Technical Support for unit monitoring analysis. During this period, the unit experienced a step-change in alkylation catalyst activity (~15%) which was not recovered. Solution: InFocus™ Unit Monitoring Tool. The InFocus Unit Monitoring ...

  • 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 ...

  • Processing heavy Canadian crude

    Reducing crude oil cost is the major incentive driving crude and vacuum unit projects to handle heavy Canadian crudes. But such crudes–Albian Heavy, Christina Lake, MacKay River and others derived from oil sands–today present refiners with a unique set of problems not just because of extra-low API gravity, but also because of asphaltenes, vanadium and nickel, high solids content and extremely high viscosity vacuum residues. To process such crudes reliably over a 4-5 ...
