Michael Massa - INVISTA
FCC Gasoline Hydrotreaters effectively reduce sulfur content to meet ever-tightening gasoline specifications. They also reduce octane through hydrogenation of high-octane olefins. INVISTA is now offering a commercially demonstrated technology to minimize this octane loss using a proprietary solvent extraction technology. The technology sweetens the thiophene-rich middle cut of the gasoline, which can then bypass hydrotreating, freeing up ~30% capacity in the hydrotreater and reducing the Octane loss to < 1 octane number. The sweetened product can be further upgraded to increase aromatics content in gasoline.
