The Gasoline Splitter column was originally designed to split full range FCC naphtha into three streams as it currently does but for different reasons. The original design was to have a light cut, a heart cut and a heavy cut. The light and heavy cuts were to be combined as a feed to the gasoline MEROX and the heart cut was to go to the CCR to produce reformate. However after the column was built in 1989 it was never commissioned in this service. In 1992 it was then suggested that it could be commissioned in a similar service to help meet legislated sulphur specifications proposed for 1995. A few modifications were made and the unit was finally commissioned in December 1994 with the heavy cut (with high sulphur content) going to 2PTR for hydrotreating. The new sulphur specifications came into force in 1995 but weren't as severe as first proposed and so the splitter was rarely used. In 1999 the strippers function changed again with the introduction of new sulphur specifications coming into the new millennium. This meant that the stripper was put into its current role as a gasoline splitter as it was originally designed.
