An oil refinery is a plant that processes crude oil. A typical plant processes thousands of barrels of oil a day, continuously. Refineries are operated continuously in order to optimize the process and the refineries’ capacity. Refineries process crude oil because in its raw form, crude oil is dangerous and produces explosive vapors.

2 Feb 2011 Oil refining is the process whereby crude oil is split — refined — into commercially useful products. Distillation is the primary means of  Continuous distillation is a process in which a chemical mixture is continuously fed into a distillation column where its contents are separated through selective  An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful petroleum products, such as  required distillates that the refinery is committed to bring to market. The economics of refining are even. On-line process analysers in crude distillation units 

For distillation, the crude oil is first heated to around 350 °C (662 °F) and then broken down into Home · Industries · Refining technology; Distillation process

Much like a simple still, in a distilling column, liquid is heated to a vapor and lifted upward to be distilled again into separate substances. This is the beginning of the refining process The process simulation system PRO/II is used to build a rigorous model for the crude oil distillation unit based on the conventional two-furnace and three-column process flow in refinery that addresses both the distillation columns and the heat exchanger network (HEN) simultaneously. The oil refining process starts with a fractional distillation column. On the right, you can see several chemical processors that are described in the next section. Very few of the components come out of the fractional distillation column ready for market. Many of them must be chemically processed to make other fractions. The Distillation Process The main way of processing crude oil is to separate it using fractional distillation. Oil is made up of many different hydrocarbons of different boiling points, so the oil is heated and different hydrocarbon chains vaporize at different times, allowing them to be collected and used as products. Vacuum distillation is a part of the refining process that helps to produce petroleum products out of the heavier oils left over from atmospheric distillation. In the refining process, the atmospheric distillation unit (ADU) separates the lighter hydrocarbons from the heavier oils based on boiling point. The ADU is capable of boiling crude oil Each refinery has its own unique arrangement and combination of refining processes largely determined by the refinery location, desired products and economic considerations. Some modern petroleum refineries process as much as 800,000 to 900,000 barrels (127,000 to 143,000 cubic meters) per day of crude oil. Distillation is the main separation process in crude oil refining. Depending on the size and complexity of the refinery, typically there could be 30 or more large distillation columns ranging from 2 to 14 m diameter.
