Abstract:  

The fixed-bed residue hydrotreating technology developed by SINOPEC Engineering Incorporation (SEI) is introduced, and its process flow and characteristics are analyzed. Taking the modification of the existing 2.0 Mt/a conventional fixed-bed residue hydrotreating unit as an example, the technical scheme, investment estimation and economic benefits are introduced. This technology is conducive to the large-scale production of single-train residue hydrotreating unit and can significantly prolong the operation cycle of the unit, achieving significant economic benefits.

Key words: fixed-bed residue hydrotreating, upflow reactor, complete set of technology
