Titles differ between systems:

IPC: Fractionating columns in which vapour and liquid flow pass each other, or in which the fluid is sprayed into the vapour, or in which a two-phase mixture is passed in one direction

CPC: 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

Full titles differ between systems:

IPC:

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

CPC:

Distillation or related exchange processes in which liquids are contacted with gaseous media, e.g. stripping ( gas chromatography B01D15/08; destructive distillation C10B; preparation of alcoholic beverages by distillation C12H6/02) > Fractional distillation > 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

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
