About producer gas or water gas generators; acetylene gas generators and similar water process gas generators; distilling or rectifying plant; heat exchange units; machinery for liquefying air or gas

cpc code 43911 covers a diverse range of industrial machinery and equipment used in the production and processing of various gases. This industry plays a crucial role in the broader manufacturing and energy sectors, providing essential components and technologies that enable the efficient generation, purification, and liquefaction of gases required for a wide array of industrial applications. From the production of acetylene and other fuel gases to the distillation and rectification of industrial gases, this industry is a vital contributor to the global economy.

Production process

The production techniques employed in this industry involve a range of specialized equipment and processes. Producer gas or water gas generators utilize coal, coke, or other carbonaceous materials to produce synthesis gas, which can then be further processed and refined. Acetylene gas generators and similar water process gas generators use a chemical reaction between calcium carbide and water to generate acetylene gas. Distilling or rectifying plants employ fractional distillation and other separation techniques to purify and concentrate various industrial gases, while heat exchange units facilitate the efficient transfer of heat in these processes. Machinery for liquefying air or gas is also a key component, enabling the production of cryogenic liquefied gases for storage and transportation.

Production inputs

The main inputs required for this industry include raw materials such as coal, coke, calcium carbide, and other carbonaceous feedstocks. Specialized machinery, including generators, distillation columns, heat exchangers, and liquefaction equipment, are also essential inputs. Additionally, the industry relies on a skilled workforce with expertise in the design, operation, and maintenance of these complex industrial systems.

Production outputs

The primary outputs of this industry are a diverse range of industrial gases, including producer gas, water gas, acetylene, and other purified and liquefied gases. These outputs are then consumed by a wide range of downstream industries, such as 35110 Basic chemicals, 35120 Fertilizers and nitrogen compounds, 35130 Plastics and synthetic rubber in primary forms, and 35200 Pesticides and other agrochemical products, which utilize these gases as essential inputs for their own production processes.
