摘要： This invention relates to a commercially viable process for extracting oxygenates from a hydrocarbon stream, typically a fraction of the condensation product of a Fischer-Tropsch reaction, while preserving the olefin content of the condensation product. The oxygenate extraction process is a liquid-liquid extraction process that takes place in an extraction column using a polar organic solvent, such as methanol, and water as the solvent, wherein the polar organic solvent and water are added separately to the extraction column.

The oxygenate extraction process is a liquid-liquid extraction process that takes place in an extraction column using a mixture of methanol and water as the solvent, wherein an extract from the liquid-liquid extraction is sent to a solvent recovery column from which a tops product comprising methanol, olefins and paraffins is recycled to the extraction column, thereby enhancing the overall recovery of olefins and paraffins.

摘要： This invention relates to a process for the purification of phenols in a feedstock containing phenols and neutral oils and/or tar bases. The process includes liquid-liquid extraction of feedstock using a solvent and a counter-solvent, and separating the resulting solvent and counter-solvent layers. Phenols are then recovered from the separated solvent layer, and counter-solvent is recovered form the counter-solvent layer. The process also includes at least one of the following additions steps i) subjecting the separated solvent layer to distillation at atmospheric pressure; ii) subjecting the separated solvent layer to distillation, recovering an organic phase from the overheads product of the distillation step and recycling it to the liquid-liquid extraction step; and iii) recovering solvent from the counter-solvent layer.
