kalkkikivilietteellä

Kalkkikivilietteellä refers to a mixture or slurry composed primarily of finely ground limestone (kalkkikivi) and water. This suspension is created by dispersing small particles of limestone in a liquid medium. The particle size and concentration of limestone in the slurry can vary depending on the intended application.

The primary use of kalkkikivilietteellä is in industrial processes, particularly in environmental technology. It is commonly employed in flue gas desulfurization (FGD) systems, where it is injected into the exhaust gases of power plants and other industrial facilities. The calcium carbonate in the limestone reacts with sulfur dioxide (SO2), a major air pollutant, to form calcium sulfite. This process effectively removes SO2 from the emissions, thereby reducing acid rain and improving air quality.

Beyond environmental applications, kalkkikivilietteellä can also be used in the production of cement, as a filler in various materials, and in some paper manufacturing processes. The properties of the slurry, such as viscosity and reactivity, are crucial for its effectiveness in these different uses. The preparation of kalkkikivilietteellä typically involves grinding limestone to a specific fineness and then mixing it with water in controlled proportions.
