Major Equipment in Atmospheric Distillation Unit (ADU) The Atmospheric Distillation Unit (ADU) is the primary processing unit in most oil refineries. It separates crude oil into various fractions based on their boiling points. The following are the key pieces of equipment found in an ADU: 1. Crude Oil Preheat Furnace: Purpose: Heats the crude oil to a temperature close to its boiling point before it enters the distillation column. Type: Typically, a fired heater that uses fuel gas or oil to generate heat. 2. Atmospheric Distillation Column: Purpose: Separates the heated crude oil into different fractions based on their boiling points. Components: Tray or Packing: Used to provide contact between the vapor and liquid phases. Reboilers: Heat the bottoms product to generate vapor. Condenser: Cools the vapor to condense it into liquid. 3. Fractionators: Purpose: Further refine certain fractions (e.g., naphtha, kerosene) to meet specific product specifications. 4. Strippers: Purpose: ...

  Knowledge Sharing#2 What is an Atmospheric Distillation Unit (ADU)? An Atmospheric Distillation Unit (ADU) is a crucial piece of equipment used in the petroleum refining process. It's designed to separate crude oil into its various components based on their boiling points. These components include gasoline, kerosene, diesel fuel, and other products. How does an ADU work? Crude Oil Feed: The process begins by heating crude oil to a high temperature. Vaporization: The heated crude oil vaporizes into a mixture of different hydrocarbons. Separation: The vapor mixture is then passed through a series of trays or packing in the distillation column. As the vapor rises, it cools, and the components with higher boiling points condense and are collected in the lower trays or sections. Product Collection: The condensed products, such as gasoline, kerosene, and diesel fuel, are drawn off at different levels of the column. Key Components of an ADU: Distillation Column: The main structure ...

  Knowledge Sharing#1 Different Units in a Refinery A refinery is a complex industrial facility that processes crude oil into various petroleum products. It consists of numerous interconnected units, each performing a specific function. Here are some of the key units found in a typical refinery: Crude Oil Distillation Units: Atmospheric Distillation Unit (ADU): Separates crude oil into various fractions based on their boiling points, such as gasoline, kerosene, diesel, and residual oil. Vacuum Distillation Unit (VDU): Further processes the residual oil from the ADU to produce heavier products like lubricating oils and asphalt. Conversion Units: Catalytic Cracking Unit (CCU): Converts heavy hydrocarbons into lighter products like gasoline and olefins. Hydrocracking Unit: Converts heavy hydrocarbons into lighter products using hydrogen. Catalytic Reforming Unit (CRU): Converts low-octane gasoline into high-octane gasoline for use in modern engines. Alkylation Unit: Combines ole...
