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

HS v2017 Code: 2705

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

HS code 2705 covers a range of gaseous fuels that are produced from coal, including coal gas, water gas, and producer gas. These gases play a crucial role in various industrial processes and energy generation, serving as important energy sources in the broader economy. The production and utilization of these gases are essential for industries such as steel manufacturing, chemical processing, and power generation, contributing to the overall efficiency and sustainability of industrial operations.

Production process

The production of the gases covered under HS code 2705 typically involves the thermal decomposition of coal or other carbonaceous materials. This process, known as gasification, involves heating the raw material in the absence of oxygen or with a limited supply of oxygen, resulting in the release of combustible gases. The specific techniques used may vary, but commonly involve the use of specialized gasifiers, such as fixed-bed, fluidized-bed, or entrained-flow gasifiers, to optimize the conversion of the solid fuel into a gaseous form.

Production inputs

The primary input for the production of the gases under HS code 2705 is coal or other carbonaceous materials, such as biomass or waste products. In addition to the raw material, the production process may require various supporting inputs, including air or oxygen, water, and specialized equipment like gasifiers, compressors, and purification systems. The availability and quality of these inputs can significantly impact the efficiency and cost-effectiveness of the production process.

Production outputs

The main outputs of the industries covered under HS code 2705 are the various gaseous fuels, including coal gas, water gas, and producer gas. These gases can be used as energy sources in a wide range of industrial applications, such as 7207 Iron and steel, 2401 Tobacco and manufactured tobacco substitutes, and 2401 Fertilizers. Additionally, the gases produced under this code may be further processed or combined with other fuels to create more refined energy products, such as synthetic natural gas or syngas.
