Atmospheric and Vacuum Distillation Units | FSC 432: Petroleum Refining
WEBDistillation of crude oil is carried out in two units, first in an Atmospheric Distillation Unit (also known as Crude Distillation Unit, CDU), with further processing of the residue from atmospheric distillation in the Vacuum Distillation Unit (VDU), as illustrated in Figure 4.2.
Vacuum distillation is a key part of the petroleum refining process
WEBDec 10, 2012 · About 80% of the refineries operating in the United States have a vacuum distillation unit (VDU), a secondary processing unit consisting of vacuum distillation columns.
Vacuum distillation - Wikipedia
WEBVacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.
Optimisation of Vacuum Distillation Units in Oil Refineries Using ...
WEBFeb 10, 2024 · To ensure the optimum performance of downstream processes in a petrochemical refinery, the operation of a vacuum distillation unit (VDU) is critical. It needs to satisfy the yield and quality requirements of the downstream process.
Simulation of Vacuum Distillation Unit in Oil Refinery: …
WEBAug 2, 2024 · The vacuum distillation unit in the oil refinery has a systematic pressure increase from 6.6 kPa to 8.26 kPa. This sequence of pressure indicates that components with distinct boiling points have been effectively separated.
Petroleum refining - Vacuum Distillation, Fractional Distillation ...
WEBA vacuum of 50 to 100 mm of mercury absolute is produced by a vacuum pump or steam ejector. The primary advantage of vacuum distillation is that it allows for distilling heavier materials at lower temperatures than those that would be required at atmospheric pressure, thus avoiding thermal cracking of the components.
Atmospheric and Vacuum Crude Distillation Units in Petroleum …
WEBJan 1, 2015 · Crude oil received by a refinery is initially distilled or fractionated into multiple “cuts” by boiling range. These cuts are further processed into final products in the refinery units. This chapter describes the initial crude fractionation process in both atmospheric and vacuum distillation units and how these units are designed.
Vacuum Distillation Unit - Petroleum Refinery Process Modeling …
WEBFeb 23, 2018 · This chapter presents the methodology for the development and applications of simulation models for vacuum distillation units (VDUs) based on plant data. It begins by describing the typical VDUs, and then presents the data requirements and reconciliation procedures for simulating VDUs.
Simultaneous optimization of crude oil refinery vacuum distillation ...
WEBMay 1, 2024 · Vacuum distillation unit (VDU) is a typical refinery process that aids in the recovery of higher boiling gas oil from atmospheric column residue [1]. Higher efficiency and less costs are attained by fractionating crude oil in two steps: First, the entire crude oil is distilled at near atmospheric pressure, then the heaviest fraction usually ...
Distillation in Refining - ScienceDirect
WEBJan 1, 2014 · This chapter reviews basic principles of refinery crude and vacuum distillation units (for more information about vacuum distillation see also Volume 2, Chapter 9) and illustrates some of the optimization opportunities. Some of the other distillation units associated with refinery conversion and …
