  • Combines ExxonMobil’s operating experience with Axens’ licensing and engineering expertise
  • Includes standalone FLEXICOKING technology license option or in combination with Axens’ H-Oil Process
  • Ideal option to meet IMO 2020 standards and eliminate high-sulfur fuel oil
  • Clean burning flexigas by-product replaces liquefied petroleum gas or liquefied natural gas while substantially minimalizing pet-coke 
  • FLEXICOKING is the leading option to co-produce power, offering 40% lower capital investment versus pet-coke gasification-based solutions

ExxonMobil (Houston – Texas) announced that ExxonMobil catalysts and Licensing LLC and Axens have signed a licensing alliance agreement to allow Axens to provide ExxonMobil’s FLEXICOKING™ technology and integrated resid conversion solutions.

Under the agreement, Axens is granted a worldwide right to market, license and provide engineering work and technical support for the design, construction and start-up of new FLEXICOKING units. The technology will be offered under a single license and engineering agreement to be provided by Axens. This new alliance leverages collective expertise to meet customer needs by providing a resid conversion solution that maximizes liquid yields and minimizes pet-coke production.

FLEXICOKING technology is a commercially proven, cost-effective, continuous fluidized bed process that thermally converts heavy feeds to lighter products and flexigas. FLEXICOKING technology, when integrated with Axens H-Oil technology, offers flexibility when upgrading residuum.  It provides smart solutions that enhance high-value liquid products as well as clean flexigas that can be used as fuel substitute or for power generation, making it an ideal option to meet IMO 2020 fuel standards.  When configured for power generation, it offers 40% lower capital investment vs. a delayed coker combined with pet-coke gasification.

We are excited to expand our partnership with Axens and provide this proven technology to the industry. In particular, FLEXICOKING offers a robust, capital and energy efficient process compared to installing a delayed coker unit and an independent gasifier complex for power or fuel gas production.By combining our owner-operator experience with Axens’ strong licensing and engineering expertise, we are able to provide advanced technologies to help meet refinery and crude to chemical-complex customer needs.
Dan Moore
President of ExxonMobil Catalyst and Licensing
We are pleased to once again partner with ExxonMobil to better meet client needs to address terminal residue conversion while producing less coke or low-value blendstock. The alliance brings a combination of FLEXICOKING and H-Oil technologies to provide a compelling new resid conversion option to our customers.
