Société Anonyme Marocaine de l’Industrie du Raffinage (SAMIR) is one of the largest companies operating in Morocco and owns the sole refinery of the country.

The refinery (125.000 bpd), located at Mohammedia, on the Atlantic coast, about 30 km north of Casablanca, has started a major expansion program as of 2005 to upgrade and add new units to the existing ones.

Front End Engineering and Design (FEED) works completed by Foster Wheeler foresee a project configuration based on the installation of a new processing complex, which will be integrated into the existing refinery.

The project also includes necessary expansion of the refinery infrastructure covering offsite and utility systems, amine treatment and sour water stripping facilities, plus 398 tie-ins to the existing system.

The upgrade scheme is designed to enable the Samir Refinery to meet future domestic demand of Morocco for refined products, particularly middle distillates and also to manufacture products for the European and other markets.

Services provided by Tekfen Engineering are civil and structural design for all units, buildings, u/g oily system and electrical /instrumentation cable channels and trenches, all off site piping works (interconnecting the new process units and utilities to the tanks and pump stations) and relevant civil / structural detailed design works.

Units are;

  • Hydrocracker Unit
  • Hydrogen Unit
  • Hydrotreater Unit
  • Vacuum Distillation Unit
  • Sulphur Recovery Unit
  • Sulphur Storage Unit
  • Amine Treatment Unit
  • Sour Water Stripper Unit
