Isomerisation unit U-618 for the Repsol refinery T-46, Tarragona, Spain.

Revamping of the isopentane unit for the production of isomerates in the C.I. at Tarragona. In this project part of the existing units (U-618 and U-613) are re-used in the building of the isomerisation unit U-618. The project includes the Pentane Continuous Catalytic Isomerization (PENEX) and the revamping of the auxiliary units (Naphtha Desulphuration, Platforming CCR, Isomax, Blending and Offsites).

This unit is part of a new gasoline manufacturing plan. It has a production capacity, starting from light naphtha with a low octane index, of 300,000 t/yr of a discharge denominated high-octane isomerate. This product is obtained free of aromatics and sulphur and with a moderate steam pressure.

SENER’s work consists of the detail engineering, purchases management and building supervision. It also carries out spot modifications on other existing units whose products go on to form part of the supply of the new isomerisation unit. It also works on the interconnections, auxiliary services and the necessary infrastructure.

  • Project data:
  • Nominal capacity: 37.5 t/h isomerate.
  • Basic Engineering: UOP.
  •  Contract type: EPCM.
  • Scope: Detail Engineering, Management of Procurement and Construction (EPCM).
