Abstract: An extraction-rectification process produces a low-volatile sump fraction and ionic fluid, in a reaction in which the ionic fraction is used as an entrainer. The sump fraction is discharged to an evaporator stage operated at a pressure of less than 500 mbar, thereby separating most of the low-volatile fraction from the ionic fluid. The low-volatile content in the ionic fluid falls to less than 5% wt. Alternatively, the discharging sump fraction is surrendered to a stripper where it is exposed to an inert gas or super-heated steam at ambient pressure or less than 900 mbar. The ionic fluid is surrendered to a further stripper where it is exposed to an inert gas or super-heated steam at ambient pressure or less than 500 mbar. The inert gas is dry air. The ionic fluid yield is returned to the extraction-rectification column. An independent claim is included for a process to separate mixtures of polar and non-polar substances that form azeotropes, or have a narrow boiling point range.

Abstract: A process for separating azeotropic or close-boiling mixtures by means of an extractive rectification in which an ionic liquid is used as entrainer, wherein a high boiling bottom product is taken off from the column in vapor form via a side offtake.

Abstract: Processes for chemical reaction and separation in a column comprising, (a) providing one or more reactants to a column; and (b) carrying out at least partially superimposed reactive distillation and extractive distillation on the one or more reactants in the column to form a reaction product mixture comprising at least two components and separate at least one of the components; wherein an ionic liquid is present in the column.

Abstract: Método para el procesamiento de una corriente de fondo que contiene uno o más productos con punto alto de ebullición y líquido iónico de una rectificación extractiva, en la cual el líquido iónico se emplea como agente de arrastre, caracterizado porque se alimenta la corriente de fondo a una etapa del evaporador la cual se opera a una presión menor de 500 mbar y se separa el producto con punto alto de ebullición, contenido en su mayor parte en forma de vapor, del líquido iónico de modo que el contenido de producto con punto alto de ebullición en el líquido iónico se reduce a concentraciones menores de 5% en peso, y a continuación se alimenta el líquido iónico tratado a un depurador (columna de agotamiento o despojamiento) cargado con gas inerte o vapor recalentado y el depurador se opera a presión ambiente.
