Introduction
The visbreaking technology is a mild thermal cracking process aiming at lowering the viscosity and pour point of residue, reducing dilution (LGO and HGO) used in residual fuel oil production. The technology is helpful for decreasing residual fuel oil production and increasing light oil yield.
Technical Characteristics
(1) Low temperature, long residence time and specially designed internals of the up-flow reactor can reduce condensation reaction and back-mixing, thus increase stability of visbroken residue and reaction conversion rate. The technology shows high light oil yield.
(2) The visbreaking technology can process various residues. Because of lower reaction temperature, the visbroken residue product is more stable.
