Manufacture of gas

NACE v2.1 Code: D35.21

About manufacture of gas

NACE code 35.21 covers the manufacture of gas, a critical industry that plays a vital role in powering economies worldwide. The production and distribution of gas, whether natural, liquefied, or synthetic, is essential for meeting the energy demands of households, businesses, and industries. This industry is a key component of the broader energy sector, contributing to the reliable and efficient supply of fuel for heating, electricity generation, and various industrial processes.

Production process

The manufacture of gas typically involves a multi-step process. Natural gas is extracted from underground reservoirs, processed to remove impurities, and then liquefied or compressed for storage and transportation. Synthetic gas, on the other hand, is produced through the gasification of coal, biomass, or other carbon-rich materials. The specific techniques employed may vary depending on the type of gas being produced, but the core objective is to convert raw materials into a refined, usable fuel source.

Production inputs

The manufacture of gas requires a range of inputs, including raw materials such as natural gas, coal, or biomass, as well as specialized equipment and machinery for extraction, processing, and distribution. Energy-efficient compressors, liquefaction plants, and pipeline infrastructure are essential components of this industry. Additionally, skilled labor, including engineers, technicians, and operators, is necessary to ensure the safe and efficient operation of gas production facilities.

Production outputs

The primary output of the gas manufacturing industry is, of course, the gas itself, which can take the form of natural gas, liquefied natural gas (LNG), or synthetic gas. These gas products are then distributed and sold to a variety of consumers, including 35.22 Manufacture of refined petroleum products, 35.30 Steam and air conditioning supply, and 49.50 Transport via pipeline, as well as residential and commercial end-users.
