Raffinointimenetelmät

Raffinointimenetelmät refer to the processes used to purify or transform raw materials into more valuable products. These methods are fundamental in industries such as petrochemicals, metallurgy, and chemical manufacturing.

In the petrochemical industry, common raffinointimenetelmät include fractional distillation (to separate crude oil into fractions like gasoline, diesel, and lubricants), catalytic cracking (to break down heavy hydrocarbons into lighter ones), and hydrocracking (to improve product quality and remove sulfur).

Metallurgical raffinointimenetelmät often involve pyrometallurgy (e.g., smelting and refining of copper, lead, or zinc) and electrometallurgy (e.g., electrolytic refining of aluminum or copper, where impurities are removed by passing an electric current through a solution containing the metal ions).

These processes enhance the purity and usability of raw materials, enabling the production of high-quality fuels, metals, and chemicals essential for modern technology and infrastructure.
