prosessikaasun

Prosessikaasu, also known as process gas, refers to any gas or mixture of gases produced as a byproduct or intermediate in an industrial or chemical process. These gases are distinct from ambient air or pure gases used as feedstock. Their composition and properties are highly dependent on the specific manufacturing or chemical reaction from which they originate.

Common examples of prosessikaasu include synthesis gas (syngas), which is a mixture of hydrogen and carbon monoxide, often produced from the gasification of coal or biomass. Another example is blast furnace gas, generated during iron production, which contains nitrogen, carbon dioxide, and carbon monoxide. Refinery gases, a mixture of light hydrocarbons, are also considered prosessikaasu, produced during crude oil refining.

The handling and utilization of prosessikaasu are critical aspects of industrial efficiency and environmental management. These gases can be valuable resources, often serving as fuel for energy generation within the plant or as feedstock for further chemical synthesis. For instance, syngas can be converted into methanol or ammonia. However, many prosessikaasut also contain impurities or pollutants that require treatment before release into the atmosphere or before they can be safely reused. Technologies such as scrubbing, adsorption, or catalytic conversion are employed to purify or detoxify these gases. The economic and environmental implications of managing prosessikaasu are significant, driving innovation in gas processing and utilization techniques.
