Pakokaasuista

Pakokaasuista, also known as blast furnace gas or BFG, is a byproduct of the iron and steel industry. It is primarily composed of carbon monoxide, hydrogen, and methane, with smaller amounts of other gases such as nitrogen and carbon dioxide. The production of pakokaasuista occurs during the smelting process in a blast furnace, where iron ore is reduced to metallic iron using coke as a fuel source.

Pakokaasuista is typically collected and cooled before being sent to a gas cleaning system. This system removes impurities and harmful substances, making the gas suitable for various applications. The cleaned gas can be used as a fuel for power generation, heating, or as a raw material in the production of chemicals and synthetic fuels.

The use of pakokaasuista as a renewable energy source is gaining attention due to its potential to reduce greenhouse gas emissions and dependence on fossil fuels. However, the availability and quality of pakokaasuista can vary depending on the specific iron and steel production process and the efficiency of the gas cleaning system.

In some regions, pakokaasuista is also used in the production of synthetic natural gas, which can be injected into the natural gas grid. This process helps to balance the supply and demand of natural gas and supports the integration of renewable energy sources into the energy system.
