Prime-G+ 1st Step 

• Removes Diolefins from HCN

• Minimizes pressure drop in selec• Allows to achieve long cycles on 

• Removes Diolefins from LCN

• Feed preparation for alkylation or 

• Converts Lt. Mercaptans/Sulfide

• Very low sulfur LCN product• No need for extractive sweetenin

• Isomerizes External Olefins into 

• Moderate octane gain on LCN
