The Rabigh project represented a pioneering example of the integration of Italian technologies and Middle Eastern infrastructure, anticipating today's needs for sustainability, energy independence, and water resilience in arid areas.
Construction:
- Technology and design: Italimpianti (now Fisia Italimpianti), using proprietary know-how.
- Civil construction and infrastructure: Almabani (Saudi Arabia), a local engineering and construction company.
Technology Used – MSF (Multi-Stage Flash Distillation):
The plant uses MSF desalination technology, which is based on rapid evaporation (flash evaporation) in multiple stages at decreasing pressures. This is a proven thermal technology, particularly suitable for applications with waste heat availability or autonomous steam production.
Production capacity:
- 1,100 m³ of desalinated water per day
- Production distributed across two independent operating lines, ensuring flexibility and continuity of service.
Operational autonomy:
The plant is completely autonomous in the production of electricity and steam, thanks to an integrated system that powers both the desalination process and auxiliary services.
