Renewable diesel processing, materials and corrosion challenges for unfamiliar feedstocks are the focus of a roundtable discussion to be hosted by the Materials Technology Institute (MTI) on June 21.

As a “drop-in” biofuel, renewable diesel is the fastest-growing addition to the suite of energy sources, notes MTI. Suppliers, fabricators and engineers will be tasked to select materials, predict damage mechanisms and establish mechanical-integrity programs for renewables units as companies build equipment and start processing renewable feeds. 

Producers of biodiesel and renewables are invited to join a roundtable meeting in Kansas City, Mo., which will be held in conjunction with MTI’s North American Technical Advisory Council (AmeriTAC). “The Roundtable aims to educate and bring a clear understanding of the ‘what’ and the ‘why now?’ of renewable diesel and its distinction from biodiesel, as well as provide knowledge of the major damage mechanisms of concern, candidate materials and pitfalls when processing renewable feeds,” says Nate Sutton, co-chair of the roundtable.

As a part of the meeting, presentations and discussions will focus on understanding the role of corrosion control documents and integrity operating windows (IOWs) for renewables units. This one-time event also will provide a forum to share information about challenges in renewables units and identify areas for MTI projects to help fill the knowledge gaps. 

The current agenda includes presentations covering: 

  • Renewable hydrocarbon biofuels overview, including laws and regulations, and the U.S. government perspective.
  • Policy and regulatory considerations for renewable hydrocarbon biofuels in the United States and Europe.
  • Pretreatment of renewable feedstock and objectives, types of pretreatment units and downstream implications.
  • Hydrotreating bio-oils and renewable diesel unit process, catalyst and layout considerations.
  • Damage mechanisms in pretreatment biofuels processing units.
  • Leveraging integrity operating windows to enhance renewable diesel unit reliability and profitability.
  • Use of polymeric coatings in storage, handling and pretreatment.
