Summary Information

  • Refinery also known as Muskiz Refinery

The Project

  • Project Type: Upgrade
  • Project Summary:
    • The coking complex will be comprised of a 36,000 barrels per stream day delayed coker, which will use FW’s leading SYDECSM delayed coking technology, plus coke handling and storage facilities and a gas concentration unit.
    • The project aims to transform the heavier components of oil ("bottom of the barrel"), whose fate is the formulation of fuel oil, light products in greatest demand: liquefied gases (propane, butane), gasoline and diesel.
  • Main Contractors:
    • Foster Wheeler: engineering, procurement and construction management of the delayed coking complex.
    • Intecsa: As a Cost-Plus-Fee contract, the project included the below execution areas:
      • FEED, front-end engineering and design, which was covered by a cost plus fee contract;
      • Complete detail engineering;
      • Procurement assistance, including inspection and expediting, being responsible for the preparation of all the purchasing inquiry package and purchase order technical documentation;
      • Supervision and technical assistance during construction
      • Commissioning and start up technical assistance.

Refining Units

  • Delayed coker - 36,000 barrels per day

Terminal Capacity

  • Crude Oil:
  • Refined Products:

Crude Supply

  • The resulting increased conversion capacity at the site will make it possible to process heavier and sourer crudes

Products Produced

  • The project will significantly increase the middle distillate yield of the refinery.
  • Fuel oil production will be reduced
