A complete understanding of ejector system performance characteristics can reduce the time and expense associated with troubleshooting poor crude vacuum distillation unit (CVDU) performance.
The products from the crude distillation unit (atmospheric and vacuum distillation) are then chosen. Typical products with their end points are shown in example E4.2.The volume percent of each cut is determined by calculating the cumulative volume percent for each fraction at its end boiling point from any of the fit procedures explained earlier in Section 3.3 and then calculating the difference.
Crude with high salt content will typically be processed through a desalter before going to distillation, to remove salts that could cause corrosion in the distillation tower. Inputs. The primary input to an atmospheric distillation unit is crude oil. This can be a single crude oil or a mixture of several different crude oil grades.
with troubleshooting poor crude vacuum distillation unit (CVDU) performance. Variables that may negatively impact the ejector-system performance of vacuum-crude distillation units include utilities supply, corrosion and erosion, fouling, and process conditions. Fig 1. Fig. 2

May 30, 2020 · An example of fractional distillation is the separation of various grades of gasoline and oil from a crude oil stock. Distillation units use containers to store separated liquids. A simple distillation unit is used when the feed stock is a single .
Crude distillation unit preflashing Implementing crude feed preflashing has been one of the common options to debottleneck crude distillation units. Switching feedstock to a lighter crude slate can cause undesired feed vaporisation at the feed furnace pass control valve and limit capacities in the crude atmospheric column and overhead .
Following installation of a new air-cooled condenser as part of its crude distillation unit's preflash tower overhead, a US Midwestern refinery began producing off-spec light naphtha that led to .
The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser.

Crude Oil Pretreatment: Desalting. Desalting is the first separation process that takes place at the front end of a petroleum refinery (i.e., prior to atmospheric distillation; Figure 1.5). Its primary objective is to prevent corrosion and fouling of downstream lines and .
This article addresses crude distillation unit (CDU) problem areas and identifies specific sections requiring investment to maintain profitability throughout a 4-5 year run length for refiners .
Crude Oil Distillation Unit (CDU): is the first processing unit in virtually all oil refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unit .
This paper presents the case history of corrosion experienced on a new atmospheric and vacuum crude distillation unit The crude charged was a low sulfur type, averaging 0.20% sulfur content, which is produced in West Texas, mostly from Ellenburger formations, of Ordovician age.
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 unit operation is critical to effective design, modification, operation and troubleshooting refinery crude units.
The crude oil distillation unit. The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units.
Typical Crude Distillation with Steam Strippers Fig. 5 a typical crude distillation unit with steam strippers for its side draws products, namely kerosene and gas oil.
The crude oil distillation unit. The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units.
The crude oil distillation plant has many components, for example, crude oil furnace, distillation towers, and heat exchangers network. Figure 16.1 illustrates a schematic diagram of the crude oil distillation system considered here. The system consists of two crude oil distillation units: (1) the atmospheric distillation unit (ADU) and (2) the vacuum distillation unit (VDU), two crude oil .
The first oil refinery unit is crude oil desalting. The desalter removes salt, water and other contaminants from crude oil prior to distillation in an atmospheric tower. The fractions recovered from the atmospheric distillation tower include naphtha, kerosene, diesel and bottoms liquid called atmospheric resid.

1.1 Crude distillation unit Crude distillation units (CDUs) separate feed to a refinery into intermediate products which are further process by the downstream units or blended into the final products. CDUs are complex distillation towers, producing several products and having many degrees of freedom which can be used to fine-tune the operation.

Energy costs for the utilities to operate an ejector-condenser unit varies widely from one part of the country to the other. Particularly with steam, it depends upon the method used to gen-erate (such as coal, oil, gas and electricity). Generally speaking, steam varies from a cost of 1.00/1000 lbs. up to as high as 15.00/1000 lbs.

Petroleum refining - Petroleum refining - Vacuum distillation: The principles of vacuum distillation resemble those of fractional distillation (commonly called atmospheric distillation to distinguish it from the vacuum method), except that larger-diameter columns are used to maintain comparable vapour velocities at reduced operating pressures. A vacuum of 50 to 100 mm of mercury absolute is .
