As one of the most precious natural resources, petroleum contains crude oil and other useful components, and we convert it into different types of fuel or products through petrochemical plants and oil refineries. A Fractionating Column is definitely indispensable in this process.

Crude oil will be heated at very high temperature and sent to the base of a fractionating column, after eliminating the salt in the oil to avoid corrosion to the petrochemical plant. When crude oil moves upwards, it will be separated into diesel, kerosene and naphtha, thanks to their different molecular weight and boiling point. Of course, these oil derivatives should be refined through more distillations to make it more pure and effective.

This type of distillation is composed of different phases, and takes place inside a single column, which has a complex structure with different entry and exit points to allow the crude oil to be reinserted for a better efficiency of the process. It is a delicate work and requires the precision in the processing and excellent quality of the plant. Here it worth mentioning that Cividac, an Italian company with over thirty years' experience, deeply studied in this field and produce metallic equipment especially for petrochemical industry in both national and international market. Their specialized management and trained operators guarantee a proper processing, eliminating errors that can compromise the quality of the product.

Besides the columns, Cividac also produces Pressure Vessels, Heat Exchangers, and so on, designed for complex industrial proposes. And the company uses all types of stainless steels and alloys to achieve the goal of quality and safety. One of the most relevant advantages of using stainless steel is its corrosion resistance, combined with safety and convenience. Thanks to the presence of alloying elements such as chromium or nickel, stainless steel become particularly resistant to corrosive attack of the atmosphere, water and many solutions of acids, salts and alkalis. And it is widely used today in the petrochemical and chemical industries, especially the type of austenitic steels with chromium, nickel and molybdenum.
