Fractionation for full boiling range gasoline desulfurization |
摘要 |
Savings in the processing of a naphtha boiling range feed containing a thiophene are achieved by fractionating the feed stream in a single dividing wall column to yield a C6-minus overhead stream, a side-draw containing the majority of the C6 and C7 paraffins and olefins, and a bottoms stream comprising C7 and heavier hydrocarbons. A dividing wall column provides better control of the concentration of both thiophene and toluene in the side-draw. Less of the valuable naphtha is lost and the amount of thiophene in the overhead product is minimized.
