Heavy Oil Upgrading
Summary
The upgrading of heavy oils means the conversion processes primary producing products that have lower boiling point than the feedstock oils. The need for upgrading technology for processing heavy oils and residue is now increasing.
Heavy oil upgrading process technology
The technology for upgrading heavy oils which converts atmospheric and vacuum residues, and other heavy oils into more valuable products, features many processes with different characteristics such as thermal cracking, FCC, hydrocracking, gasification and so on, enabling the effective utilization of crude oils. TOYO has designed and constructed over 20 facilities for upgrading heavy oil resources both within Japan and abroad, for various licensed processes of UOP, AXENS, KBR, Lummus, Shell, Exxon Mobil, Foster Wheeler, Petrobras and many others.

Features and benefits of visbreaking process technology
 Visbreaking |
Visbreaking is a thermal cracking process that intends to reduce the viscosity and pour point of residual oil without using catalyst, from which high-quality fuel oil and a small amount of naphtha and distillate are obtained. |
