  • Cycle life estimates for catalyst reload vary from 7 to 44 months

    It is very difficult to accurately predict the cycle life for a hydroprocessing unit. This is especially true with today’s highly variable feed slates. Despite this fact, catalyst suppliers are always asked to estimate cycle life when bidding for a catalyst reload, and they comply with the request even when it is nearly impossible to make a decent estimate with the available data.   In one recent case, four catalyst suppliers were asked to make reload proposals, ...

  • Faster lead time for emergency catalyst delivery

    An incident caused irreversible poisoning of a catalyst bed in a hydroprocessing unit. The incentive for immediate catalyst replacement was $400,000 per month, and the quoted lead time was unacceptably long.  The refiner used our network to identify two feasible alternatives for faster delivery.  The outcome was 2 months faster lead time and $800,000 margin saved. Improved refinery lab accuracy:  Refinery lab analyses of FCC gasoline and reformate were incorrectly ...

  • High aromatic/nitrogen feeds cause rapid initial deactivation in pilot plants

    A feed sent to C Solutions in Thessaloniki, Greece caused catalyst to deactivate very rapidly when introduced on day one of a pilot plant run.  Analysis showed the feed to be full of high boiling aromatics and high in nitrogen. The pilot plant run was restarted with the usual 3-day break-in on straight run feed, and the catalyst lined out with the usual moderate initial deactivation, leading to a successful 40 - day test on the difficult feed.    This problem ...

  • Hoekstra war stories

    In the past two years, there have been many field failures in ultra-low sulfur diesel (ulsd) hydrotreaters. By field failures we mean short cycles of less than half the expected cycle life. The root cause of these failures was overestimating what a catalyst can do in a hydrogen starved unit. For example, one unit experienced a cycle life of just 1 year versus an estimated 3 year life on a very expensive catalyst. After two more short cycles of less than one year on other ...

  • How to evaluate, select, and work with a precious metals refiner.

    Precious metals are used in many processes and products for facilitating and/or speeding chemical reactions, pollution abatement, chemical/pharmaceutical production, electroplating, automotive catalytic reactors, jewelry, film, and hundreds more. Escalating values of most precious metals have forced users to view their precious metals purchasing and recovery management programs with a keen focus on costs at all levels. Selecting and working with an established, reliable — ...

  • Hydrogen-starved unit struggles to make ULSD

    This is a 36 bar (525 psig) unit that was converted to ulsd service. The first two cycles used Albemarle KF-757 and lasted 6 months compared to one year expected cycle life. They switched to Topsoe catalyst for the next cycle and saw no improvement. Two suppliers recommended replacing the reactor internals; but Johnson Matthey did a convincing analysis showing the unit was constrained by hydrogen supply, not flow distribution, and new internals would not fix the root ...

  • 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™ ...
