Prime-G+® stems from Axens' extensive experience acquired in cracked naphtha HDS and selective hydrogenation of LPG and gasoline. Although the naphtha splitter may be optional depending on the required HDS severity, the association of a Prime-G+® selective hydrogenation unit (SHU) with a splitter for light naphtha desulfurization and sweetening ideally complements the selective HDS on the heavier fraction.
Within the preferred arrangement, the "Prime-G+® 1st Step" produces an olefin-rich light cracked naphtha (LCN) and the sulfur-rich heavy cracked naphtha (HCN) is sent to the selective HDS to maximize octane retention.
Prime-G+® offer is particularly flexible allowing different process configurations to best fit the gasoline pool requirement and also maximize refinery profitability.
The first step of Prime G+® technology feature is in offering excellent preparation for the feed of the light gasoline etherification (TAME / TAEE) unit. The TAME/TAEE process ideally complements Prime-G+® technology in compensating for the octane loss and regaining the octane barrels.
One other technology features of the Prime G+® is, being coupled with Axens’ Polyfuel® technology, to offer the possibility to turn Olefinic feedstock into high value Products. LPG and LCN Upgrading towardistillates while maintaining good quality gasoline.
