Crude oil distillation cuts
conventional crude oil distillation unit are possible. Figure 1-2 shows one higher than the corresponding draw temperature of a single VGO cut. Lighter. Crude oil distillation is therefore, the physical separation of oil of little or no to a certain temperature and pressure depending on the preferred distilled cuts. 14 Aug 2018 MODULAR CRUDE OIL TOPPING REFINERY: THE TOTAL UTILIZATION OF ALL DISTILLED CUTS. Article (PDF Available) · December 2016 Primary crude oil cuts in a typical refinery include gases, light/heavy naphtha, kerosene, light gas oil, heavy gas oil and residue. From these intermediate refinery 11 Feb 2020 emissions to fight climate change, scientists have created a new material that has the potential to reduce emissions from crude oil refining.
Simple distillation—or first-level refinement—of different crude oils produces different results. For example, the U.S. benchmark crude oil, West Texas Intermediate (WTI), has a relatively high natural yield of desirable end-products, including gasoline.
The first step in the refining process is the separation of crude oil into various fractions or straight-run cuts by distillation in atmospheric and vacuum towers. The main fractions or “cuts” obtained have specific boiling-point ranges and can be classified in order of decreasing volatility into gases, light distillates, middle distillates, gas oils, and residuum. Atmospheric crude distillation unit. Crude oil obtained from the desalter at temperature of 250 °C–260 °C 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 crude oil is preheated by exchanging heat with some of the hot cuts from the atmospheric distillation column. Water is added and mixed with the crude to “desalt” or remove the inorganic salts, such as sodium chloride. The desalted crude then proceeds through several more pre-heat exchangers, The main separation step in any crude oil refinery is atmospheric or primary distillation. Atmospheric distillation fractionates the crude oil into various distillates, fractions, or cuts of hydrocarbon compounds based on molecular size and boiling)point range [e.g., light ends, propane, butanes, straight ) run naphthas (light and heavy), kerosene, straight-run gas oils (light and heavy), and atmospheric residue] (Figure 1.5). The quality of separation in fractional distillation can be calculated using the designated cut points (at 5% vol and 95% vol) for the two adjacent fractions, termed as light and heavy. As shown below, the difference in temperature (δT) between 5% vol temperature of the heavy fraction and 95% vol temperature
At this refinery, ships carrying crude oil arrive about every 10 days and off load This combination of heat and low pressure is equivalent to distilling at a cut
All simple refineries have distillation towers in which crude oil is heated until various “cuts” boil off. When condensed, many of these cuts are similar to refined

This last cut is sent to a primary vacuum tower and produces gas oil (VGO), spindle oil and two other heavier cuts for lubes production. There is also a secondary
On average, U.S. refineries produce, from a 42-gallon barrel of crude oil, about 19 to 20 gallons of motor gasoline, 11 to 12 gallons of distillate fuel, most of which is sold as diesel fuel, and 4 gallons of jet fuel. More than a dozen other petroleum products are also produced in refineries.

More than a dozen other petroleum products are also produced in refineries. Crude oil processing is the first step in the petroleum refinery. This distillation occurs in the refinery crude unit. The objectives of the unit include rejection of major contaminants and an initial cut of the crude oil into streams for further processing. Understanding the fundamentals of crude Crude oil distillation simplified process shows in animation that how crude oil process is separates the the crude oil in its basic components before refining them to end product.
