Abstract (en)
Fouling during separation of light ends from a mixed hydrocarbon feed in a fractionating tower, particularly in the depropanizer in ethylene separation from steam cracked naphtha, is reduced by fractionating the vapour portion of the feed in a first tower (21) before fractionating the liquid portion of the feed together with the bottoms from the first tower in a second tower (24) operating at a lower pressure than the first. The bottoms temperature of second fractionation is thereby reduced which reduces fouling. Energy consumption is reduced by decreased refrigeration and heating requirements.
