S-Oil contracts Axens on Korean refinery upgrade
7/20/2015 12:00:00 AM
Axens has been awarded several contracts for the expansion of the existing residue conversion facilities at S-Oil’s Onsan refinery in South Korea, officials announced on Monday.
The residue upgrading complex project (RUCP) is aimed at reducing fuel oil production while producing propylene through the conversion of atmospheric residue and will include the world’s first commercial high-severity FCC unit (HS-FCC).
For this complex (RUCP), Axens says it has supplied the following technologies:
- An atmospheric residue desulfurization unit (Hyvahl) for the production of diesel and improvement of residue quality. The Hyvahl unit includes a permutable reactor system (PRS);
- A high-severity FCC unit (HS-FCC)–for the conversion of the hydrotreated residue produced by the Hyvahl unit. The HS-FCC technology bridges the refining and petrochemical gap by maximizing propylene production using an innovative down flow reactor;
- An unsaturated liquefied petroleum gas (LPG) extractive sweetening unit (Sulfrex) for the treatment of the LPG cut originating from the HS-FCC unit upstream of polymer-grade propylene recovery process (PRU).
Axens says it will provide technology licenses, basic engineering, catalysts, adsorbents and proprietary equipment for the complex.
In addition, Axens says it has supplied the following technologies:
- A selective desulfurization unit (Prime-G+) for the treatment of the HS-FCC gasoline;
- A C4-stream processing section including a C4 selective hydrogenation unit, a MTBE unit, a super-fractionator and a butane isomerization unit. This section will produce MTBE and 1-butene which will be used as a co-monomer in polymerization applications, as well as isobutane feed for an alkylation unit.
The RUCP scheme is the result of a conceptual study carried out by Axens’ performance programs business unit, which provides services for new and existing plants in the refining and petrochemical industries.
