DuPont hydroprocessing technology undergoes start-up at transmix processing facility

DuPont Clean Technologies (DuPont) has announced the start-up of one of the world’s first IsoTherming® hydroprocessing technology applications to treat diesel from a transmix processing facility.

Transmix is a mixture of refined products that forms when transported in pipelines. This mixture is typically a combination of gasoline, diesel and/or jet fuel.

The IsoTherming hydrotreater, located at the Gladieux Processing (Gladieux) transmix facility in Huntington, Indiana, US, has completed the performance test, certifying that the unit is exceeding performance guarantees and producing 5 000 bpd of ultra-low sulfur diesel (ULSD) containing less than 10 ppmw sulfur.

“With implementation of the global marine fuel sulfur cap, we needed a swift, cost-effective hydrotreating solution for the diesel stream from our transmix processing facility,” said Tim Wagner, president of Gladieux.

The IsoTherming hydroprocessing technology uses a novel liquid phase reactor system. It is suitable for kerosene, transmit, diesel and FCC feed hydrotreating, as well as mild hydrocracking, dewaxing, GTL and heavy oil upgrading.

Growing global demand for cleaner transportation fuel continues to drive refiners toward operations that maximise hydroprocessing capacity and capability either through unit debottlenecks or new unit construction. More stringent environmental regulations and the processing of cost-advantaged sour and heavy feedstocks make meeting this demand even more challenging.
