Design and Construction of Atmospheric and Vacuum Distillation Columns by INVEXOIL

Invexoil designs and builds distillation towers for separation of components from liquids through distillation processes. These towers are used in oil refining, petrochemicals, pharmaceuticals and food processing where separation of mixtures into its parts is required.

Benefits of Invexoil’s Distillation Towers

• Efficient Separation: Invexoil’s distillation towers are designed for high separation of different components from liquids. Suitable for processes where light and heavy fractions are to be extracted from a mixture, to get the best purity of each product.
• Customizable Design: Distillation towers are built to meet each application’s requirements. They can handle various flow rates, pressure, and temperature conditions according to the process needs.
• Optimized Heat and Mass Transfer: The design ensures maximum heat and mass transfer, to reduce energy consumption and improve distillation.
• Advanced Materials: The towers are made of high-quality materials to withstand high temperature, pressure, and corrosive substances, for long and reliable performance.
• Modular Design for Flexibility: The towers can be designed in modular form to fit into existing systems or to expand as per future needs.
• Full Automation: Equipped with modern control systems, Invexoil’s distillation towers are fully automated for monitoring and control of variables like temperature, pressure, flow rates, and distillation fractions. This results in higher operational efficiency, precision, and safety.

Features of Invexoil’s Atmospheric Distillation

Atmospheric distillation is a process of separating components in crude oil which is done under atmospheric pressure.

• Pressure: Atmospheric distillation uses pressure almost similar to atmospheric pressure (1.2-1.5 atm).
• Theory: Atmospheric distillation is used to separate the low boiling fraction of the mixture.
• Fractionation: Atmospheric distillation separates the light fractions of the mixture.
• Degradation of the Key Components: Atmospheric distillation does not degrade the component.

Applications of Distillation Towers in Industries

1. Oil Refining Industry: To separate components from crude oil, gasoline, diesel, and base oils.
2. Petrochemical Industry: In the production of petrochemical products and separation of raw materials for the production of plastics, fertilizers, and other goods.
3. Pharmaceutical Industry: To separate pharmaceutical compounds and produce pure pharmaceutical products.
4. Food Industry: For refining and separating components in processes such as producing edible oils, essential oils, and other food products.

Process description of Atmospheric Distillation (ADU)

Atmospheric Distillation is the first process and has the largest capacity in a refinery complex. Different fractions are produced based on their boiling point and further processed in the downstream units to produce desired products. In this process, preheated crude oil (heated to around 250-260°C) is further heated to around 350°C. This heated crude oil is then fed into a distillation column where the top pressure is maintained around 1.2-1.5 atm (almost atmospheric pressure).

The feed to the atmospheric distillation column is desalinated and preheated. The components separated by this distillation are hydrocarbons such as fuel gases, naphtha, kerosene, diesel and fuel oil. The residue at the bottom of the atmospheric distillation column is called heavy hydrocarbon fraction. This fraction is sent to vacuum distillation.
