Prime-G+ HDS Benefits

High performance- Deep HDS (less than 10 wppm product S)

- Low Octane Loss, Low product mercaptan Low Cost and Utilities

- Well suited for idle units reutilization

Simple and Reliable Process- Easy operation

- Excellent stability Industrially proven at Ultra Low Product Sulfur

Ability to Co-process other Streams than FCC

Prime-G+ 1stStep - SHU + Splitter

Removes Diolefins from HCN

- Minimizes pressure drop in selective HDS

- Allows to achieve long cycles on selective HDS

Removes Diolefins from LCN

- Feed preparation for alkylation or etherification

Converts Lt. Mercaptans/Sulfides to Heavy Sulfur

-Very low sulfur LCN product

- No need for extractive sweetening

Isomerizes External Olefins into Internal Olefins

- Moderate octane gain on LCN
