19 - Manufacture of coke and refined petroleum products

This Chapter has been extracted from the ONS Explanatory Notes and provides a more detailed explanation of possible activities that could fall within the SIC Codes related to the Chapter.

This division includes the transformation of crude petroleum and coal into usable products. The dominant process is petroleum refining which involves the separation of crude petroleum into component products through such techniques as cracking and distillation. This division also includes the manufacture for own account of characteristic products (e.g. coke, butane, propane, petrol, kerosene, fuel oil etc.) as well as processing services (e.g. custom refining).

This division includes the manufacture of gases such as ethane, propane and butane as products of petroleum refineries.

Not included, is the manufacture of such gases in other units (20.14), manufacture of industrial gases (20.11), extraction of natural gas (methane, ethane, butane or propane) (06.20), and manufacture of fuel gas, other than petroleum gases (e.g. coal gas, water gas, producer gas, gasworks gas) (35.21).

The manufacture of petrochemicals from refined petroleum is classified in division 20.

19.1 Manufacture of coke oven products

19.10 Manufacture of coke oven products

This class includes:
- operation of coke ovens
- production of coke and semi-coke
- production of pitch and pitch coke
- production of coke oven gas
- production of crude coal and lignite tars
- agglomeration of coke

This class excludes:
- manufacture of coal fuel briquettes, see 19.20

19.2 Manufacture of refined petroleum products

19.20 Manufacture of refined petroleum products

19.20/1 Mineral oil refining

This subclass includes the manufacture of liquid or gaseous fuels or other products from crude petroleum, bituminous minerals or their fractionation products. Petroleum refining involves one or more of the following activities: fractionation; straight distillation of crude oil; and cracking.

This subclass includes:
- production of motor fuel: gasoline, kerosene etc.
- production of fuel: light, medium and heavy fuel oil, refinery gases such as ethane, propane, butane etc.
- manufacture of oil-based lubricating oils or greases, including from waste oil
- manufacture of products for the petrochemical industry and for the manufacture of road coverings
- manufacture of various products: white spirit, vaseline, paraffin wax, petroleum jelly etc.
- manufacture of petroleum briquettes
- blending of biofuels, i.e. blending of alcohols with petroleum (e.g. gasohol)

This class also includes:
- manufacture of peat briquettes
- manufacture of hard-coal and lignite fuel briquettes

19.20/9 Other treatment of petroleum products (excluding mineral oil refining/petrochemicals manufacture)

This subclass includes:
- manufacture of oil-based lubricating oils or greases, including from waste oil
