As shown in Figure 3.2, the Light Ends Unit consists of a sequence of distillation processes to separate the overhead distillate product from the atmospheric distillation column into five streams consisting of methane and ethane (C 2 and lighter), to propane (C 3), butane (C 4), light naphtha, and heavy naphtha.The fraction C 2 and …
WebDistillation Processes. The first refinery, opened in 1861, produced kerosene by simple atmospheric distillation. Its by-products included tar and naphtha. It was soon discovered that high-quality lubricating oils could be produced by distilling petroleum under vacuum. However, for the next 30 years kerosene was the product consumers wanted. WebNov 21, 2024 · To separate petroleum products from Crude oil, the distillation of crude oil is performed and it is atmospheric distillation. After atmospheric distillation which is considered as a primary process, leftover heavy oils are feed to a vacuum distillation unit where the separation of compounds is done in a vacuum.
WebTemperature measurement. Crude oil travels from the primary heat exchanger to the atmospheric distillation unit, where it is separated into various ”fractions” or “cuts”, … WebDistillation cuts. Also known as: distillation fractions, straight run streams. Distillation cuts are the output streams from a distillation tower. They are called "cuts" because they are the result of separating the crude oil into its constituent parts based on the different temperatures at which they evaporate and condense (e.g., cut points ...

Crude oil exits from the desalter at temperature of 250 °C–260 °C and is further heated by a tube-still heater to a temperature of 350 °C–360 °C. The hot crude oil is then passed into a distillation column that allows the separation of the crude oil into different fractions depending on the difference in volatility. The pressure at the top is maintained at 1.2–1.… tela aireadaWebAug 6, 2024 · The distillation in the crude distillation unit is carried out consecutively in two ways: atmospheric and vacuum.
