Abstract
Process for removing oxygen-containing organic compounds from mixtures of hydrocarbon compounds, in which a liquid phase () containing hydrocarbons and oxygenates is charged to a first column (), a light fraction is separated as top product () by distillation, and that a heavier C4+ fraction is removed from the bottom, the light fraction () and a gaseous mixture of hydrocarbons and oxygenates () is charged to a second column (), and separated into a light and a heavy hydrocarbon fraction distillation, and an additional solvent () is supplied to the upper part of the second column (), which dissolves the oxygenates and, the solvent and oxygenates being discharged as bottom product () and a hydrocarbon product (), which is free from oxygenates leaves the top of the column (). The solvent optionally is wholly or partly regenerated and recirculated to the extractive distillation column.
