With the advent of clean fuels and the constantly changing sources of crude, it's important for refiners to understand the many variables for control and optimization to maximize profitability. Read on to discover what crude distillation is and why crude distillation is so important in the oil refining process. Overview Crude distillation is the first step in …
The refining process. Every refinery begins with the separation of crude oil into different fractions by distillation. The fractions are further treated to convert them into mixtures of more useful saleable products by various methods such as cracking, reforming, alkylation, polymerisation and isomerisation.

Salt is the common name for the substance sodium chloride (NaCI), which occurs in the form of transparent cubic crystals. ... About 70% is used in the chemical industry, mostly as a source of chlorine. ... At this point foreign matter is removed from the salt, a process known as picking. Metal is removed by magnets and other material by hand ...
Refining of metals is the final process. After the extraction process the metal is free from impurities. The refining method to be chosen will depend on the physical and chemical properties of a particular metal. There are different methods of making a metal pure : Distillation. Liquation. Poling. Electrolysis. Zone refining. Vapour Phase refining
Demand for lithium for batteries and other green technologies is exploding. The industry must develop sustainable methods to remove and process the element from ores and brines to avoid ...
