Coal gas, water gas, producer gas and similar gases, other than petroleum gases and other gaseous hydrocarbons

cpc code 172 encompasses the production and distribution of various types of industrial gases, including coal gas, water gas, and producer gas. These gases play a crucial role in a wide range of industrial processes, serving as essential inputs for numerous manufacturing and energy sectors. The production and utilization of these gases contribute significantly to the overall efficiency and sustainability of the global economy.

The primary production techniques for the gases covered under cpc code 172 involve the thermal decomposition or gasification of solid fuels, such as coal, biomass, or other carbonaceous materials. This process typically involves heating the raw materials in the absence of oxygen, which results in the release of combustible gases. The specific methods used may vary, but often include techniques like coal gasification, biomass gasification, and the use of producer gas generators.

The main inputs required for the production of the gases under cpc code 172 include solid fuels, such as coal, biomass, or other carbonaceous materials, as well as various types of equipment and machinery necessary for the gasification and purification processes. Additionally, the production of these gases may require access to reliable energy sources, water, and specialized labor with expertise in gas processing and handling.

The primary outputs of the industries covered under cpc code 172 are the various types of industrial gases, including coal gas, water gas, and producer gas. These gases are then consumed by a wide range of other industries, such as 231 Manufacture of coke oven products, 351 Electric power generation, transmission and distribution, and 201 Manufacture of basic chemicals, fertilizers and nitrogen compounds, plastics and synthetic rubber in primary forms, among others. The efficient production and distribution of these gases are crucial for the smooth operation of many downstream industries.
