  • What is a vacuum crude distillation unit?
  • Whether you have a grass roots or revamp application, we can provide you with an optimized, robust solution to meet your most demanding VDU requirements. The vacuum crude distillation unit takes the reduced crude from the atmospheric column and produces light ends, gas oils, lubricants, and bottoms residue.
  • What is crude oil vacuum distillation?
  • In the crude oil vacuum distillation process, the side-stream products and VR are further processed in downstream units and converted into more commercially valuable products. Besides, the heat is recovered by the preheat trains.
  • What is a vacuum distillation unit (VDU)?
  • Such unit consists of a pre-flash unit, an atmospheric distillation unit, and a vacuum distillation unit (VDU). VDU is part of a typical refinery process that helps to further recover the higher boiling gas oil from the atmospheric residue of an atmospheric distillation unit.
  • Is vacuum distillation a dynamic process in oil refining?
  • Despite the abundant literature on distillation processes in the oil refining industry, the dynamic aspect of vacuum distillation operations is still mostly unknown, even though previous research has concentrated primarily on steady-state modeling and simulation of crude oil dehydration and desalination.
  • How to design a vacuum distillation unit?
  • Conceptual framework for optimisation of the vacuum distillation unit (VDU) Generally, two types of models can be used to design the crude distillation unit: the shortcut model and the rigorous model. A rigorous model can simulate mass balance, energy balance, and equilibrium relations for every stage of the distillation unit.
  • What is a crude distillation unit (CDU)?
  • Some refinery systems refer to the crude distillation unit (CDU) products, which are often fractions emerging as percentages of naphtha, petroleum, and gas oil, using terms like gasoline, jet fuel, and diesel . Gu et al. describe steady flow modeling and simulation of three vacuum distillation columns in crude oil plants.
