Crude Oil Distillation Process

The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. The steps of fractional distillation are as follows:

Industrial Application of Crystallization

Crystallization is one of oldest unit operation is chemical & process engineering. In pharmaceutical , food, fertilizer ... etc industries crystallization is widely used. In pharmaceutical & food industry the purity of crystals are highly important while some of other industries need crystal size & quantity. There are many equipments available in industry.

• Tank crystallizers
• Scraped surface crystallizers
• Double-pipe scraped surface crystallizer
• Circulating-liquid evaporator-crystallizer
• Circulating-magma vacuum crystallizer

These are some of equipments which is found in industries.
