B01D3/26 - CPC Classification

Classification description:

Distillation or related exchange processes in which liquids are contacted with gaseous media, e.g. stripping; Fractional distillation or use of a fractionation or rectification column Fractionating columns in which vapour and liquid flow past each other, or in which the fluid is sprayed into the vapour, or in which a two-phase mixture is passed in one direction
