DuPont Clean Technologies announced that it has signed a contract with ISAB S.r.l. (ISAB, wholly owned by LUKOIL) to revamp the refinery’s existing trickle-bed diesel hydrotreater at the Priolo Refinery in Siracusa, Italy with the IsoTherming Hydroprocessing Technology. ISAB commissioned DuPont for the project in an effort to increase unit capacity to a target of 205 m3/hr (31,000 bbl/d), while also extending catalyst cycle length.
IsoTherming Diesel Hydrotreaters enable refiners to produce high-quality, low-sulfur fuels that comply with increasingly stringent environmental requirements, but at lower energy consumption rates and operating costs than trickle bed hydroprocessing units. T
“We are delighted to have the opportunity to work with ISAB on this project,” said Kevin Bockwinkel, global business manager, IsoTherming Hydroprocessing Technology. “In addition to producing high-quality, low sulfur fuels, our IsoTherming technology will grant ISAB the opportunity to process more difficult, cracked feedstock without sacrificing product quality all while extending catalyst cycle length. Utilizing the IsoTherming technology allows us to accomplish all of this without additional catalyst volume, thus maximizing the benefit to the refinery without the need for significant capital investment. We look forward to expanding upon our strong relationship with ISAB and continuing it for years to come.”
Startup of the IsoTherming Diesel Hydrotreater at the Priolo Refinery is expected to take place by 2024.
