The design and engineering for the power and desalination units are based on a proven off the shelf technology with successful track records.
The steam turbines are back-pressure units using Siemens established modular design technology coupled directly to synchronous generators. The desalination technology is multi- stage flash (“MSF”) which is a thermally driven process that involves heating brine with steam and then allowing the hot water to flash off at successively lower pressures. The MSF process is a success story for a large unit size throughout the Middle East and worldwide.
The EPC contractors for the Project are Siemens AG of Germany for the power train and Doosan Heavy Industries & Construction of Korea for the desalination units.
The plant operation is in compliance with both KSA’s Presidency of Meteorology and Environment (“PME”) environmental standards and requirements for air and water pollution, permissible noise levels and soil contamination and with applicable World Bank standards. Shuaibah III IWPP is the first plant in the KSA utilising the Flue Gas Desulphurisation (FGD) system, along with low NOx burner design and Electrostatic Precipitator (ESP). Continuous Emission Monitoring System (CEMS) is installed for round the clock monitoring.
Independent environmental audit is being carried out in 6-monthly interval to ensure continuous compliance with the regulations. SWEC also undertakes an added initiative in measuring Ground Level Concentration (GLC) on yearly basis.
