Deep hydrodesulfurization (HDS) of FCC gasoline (the largest sulfur contributor in the gasoline pool) is required to reduce gasoline pool sulfur content. Technologies must meet the following challenges:
Good octane retention
Excellent gasoline yield retention
No RVP increase
Minimum hydrogen consumption
Operational reliability
Ability to co-process other sulfur-rich streams
Although the naphtha splitter may be optional depending on the required HDS severity, the association of a Prime-G+TM selective hydrogenation unit (SHU) with a splitter for light naphtha desulfurization and sweetening ideally complements the HDS on the heavier fraction.
To ensure still further that customers receive the best available solution, Axens and BP have recently formed an alliance that enables Axens to offer exclusively BP’s new OATSTM (Olefin Alkylation of Thiophenic Sulfur) process.
Prime-G+TM stems from our extensive experience acquired in cracked naphtha HDS and selective hydrogenation of LPG and gasoline. Axens’ Prime-G+TM technology has been selected by 150 customers (end 2007) and has been established as the industry’s benchmark process.
