Maximum Conversion of Vacuum Residue to Naphtha and Diesel. The UOP Uniflex™MC™ process converts vacuum residue to maximize the production of clean distillates. The process has been proven on a commercial scale, with years of efficient and reliable operation providing robust economic returns.
The kinetic rate constants proposed by Sanchez at al.[1] for hydrocracking of vacuum residue at 380, 400 and 420oC were used in a simple kinetic model using a series of CSTRs to calculate the residue conversion and the VGO, distillate, naphtha and gaseous products concentrations and molar flow rates.
Apr 16, 2014 · The residue from vacuum distillation (VDR) can be upgraded into marketable products and fuels using processes such as visbreaking, deasphalting, and coking, as will be discussed in later sections. [3] Refining Overview - Petroleum, Products and Processes, AIChE, 2000, p. 10-4.
This is the bottom product from the vacuum distillation unit. Just as in the case of the atmospheric residue it has several options for its use in meeting the refinery's product slate. Distillation of crude oil under reduced pressure produces the vacuum residue. We .
Maltenes and Asphaltenes of Petroleum Vacuum Residues 95 Fainberg et al. (1996) have modified the ASTM D4124 (Drews, 1989) method by carrying out extraction in soxhiet apparatus, by heptane. By using pentane, asphaltenes precipitate along with polar aromatics. Propane precipitates along with asphaltenes a mixture of polar aromatics and
To make full use of heavy oil by thermochemical conversion, the thermal behaviors of vacuum residue (VR) were investigated first by thermogravimetry – Fourier transform infrared spectrometer (TG–FTIR) and then via a laboratory-scale fluidized bed reactor (FBR). The TG–FTIR results showed that the changes in the absorbance of volatiles during thermal cracking were consistent with the ...
The coking procedure transforms the vacuum residue into solid, liquid and gas products. After some time, the heavy feedstock is heated and pumped to insulated drums where the large molecules are divided into smaller molecules, liquid products, producing gas, and coke.

hydrotreating of the hydrocracked gas oil and lighter products to produce SCO. The first process hydrocracks vacuum residue in ebullated bed reactors in a single stage without heavy oil recycle. Bitumen derived naphtha and gas oils from the crude unit are also charged to the single stage hydrotreating section of this plant.
As the name vacuum distillation implies, the distillation column is under a vacuum, or significantly less than atmospheric pressure of 760 millimeters of mercury (mmHg). At low pressures, the boiling point of the ADU bottoms is low enough that lighter products can vaporize without cracking, or degrading, the oil.

The heaviest and the most contaminated component of crude oil is the vacuum distillation residue (VDR), also referred to as the bottom-of-the-barrel. There are ple processing paths to upgrade VDR into usable products. One process is called deasphalting, which removes the heaviest fraction of VDR as asphalt that is used mainly to pave roadways.

Vacuum distillation is a method of distillation performed under reduced pressure, which lowers the boiling point of most liquids. As with distillation, this technique separates compounds based on differences in boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve, will cause the compound to decompose or simply to save energy in heating.
The vacuum residue itself also figures in the production of bitumen. Where non-energy products are significant in the refinery's product slate, the vacuum residue as produced is the key component in bitumen production. Categories: Fractions from atmospheric and vacuum distillation ...
