Division · Nomenclature d'Activités Française (2025)

Where 19 sits

This division includes the transformation of crude petroleum and coal into usable products. The dominant process is petroleum refining that involves the separation of crude oil in components by such techniques as cracking and distillation.
This division includes the manufacture of gases (for example, ethane, propane and butane) as as products of petroleum refineries.
This division also includes the manufacture for own account of characteristic products (e.g. coke, butane, propane, gasoline, kerosene, fuel oil), as well as treatment services (for example, refining on account).

This division excludes the manufacture of these gases in other units (see 20.14Y), the manufacture of industrial gases (see 20.11Y), the extraction of natural gas (methane, ethane, butane, or propane) (see 06.20Y), and the manufacture of gases other than petroleum gases intended for the supply of gaseous fuels via a permanent distribution network (e.g., coal gas, water gas, producer gas, town gas) (see 35.21Y).
The manufacture of petrochemicals from refined petroleum and the manufacture of liquid biofuels are classified in division 20.
This division does not include the manufacture of such gases in other units, see 20.14Y -the manufacture of industrial gases, see 20.11 There, the extraction of natural gas (methane, ethane, propane, butane, or propane), see 06.20Y and the manufacture of gas, other than petroleum gases for the provision of gaseous fuels through a network of permanent distribution (for example, coal gas, gas water, gas gas, gas works gas), see 35.21Y
The manufacture of petrochemicals from refined petroleum and the production of biofuels liquids are classified in division 20.
