Metallurgy Metallurgy Refining: Refining is the final procedure for removing (and often recovering as byproducts) the last small amounts of impurities left after the major extraction steps have been completed. It leaves the major metallic element in a practically pure state for commercial application. The procedure is accomplished in three ways: refining by fire, by electrolytic, or by

The petrochemical industries produce huge quantities of oily sludge during the crude oil refining process that includes different sources such as slop oil emulsions, crude oil tank bottoms, onsite effluent treatment ponds, and oil or water separators (Hu et al., 2013). These oily sludges consist of unruly mixtures of total petroleum hydrocarbon

During the process, which is also known as topping (refining) Another name for atmospheric distillation., the oil is heated at the bottom of a 60meter distillation column at a temperature of 350 to 400°C, causing it to vaporize. The vapors rise inside the column while the heaviest molecules, or residuals, remain at the bottom, without vaporizing.

The term "refining" is used in a narrower context. Henry Cort''s original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
