The low emission level is based on a combination of well-proven and new advanced abatement techniques capable of com-plying with the most stringent emission norms. The power producing units of the plant are eight diesel generation sets, Wartsila 18V46 medium speed dieselen-gines with ABB AMG1600 alternators, each rated 17.1 MWe, and as bottom cycle one common Dresser Rand steam turbine generator with a Converteam alternator rated 13.2 MWe. The fuel of the plant is Heavy Fuel Oil with a maximum sulfur content of1%. The flue gas abatement includes NOx abatement by Selective Catalytic Reduction, SO, and Particulate abatement by dry Flue Gas Desulfurization with Sodium Bi-Carbonate injection followed by filtration in a BagHouse filter. The plant is cooled by Sea Water. The obtained net plant electrical efficiency with the extensive utilization of the exhaust gas energy in boilers and the steam turbine generator is 46.9% with due consideration of auxiliary power consumption for emission abatement purposes. In addition the plant include two desalination units, each rated 700 m3 /day driven byengine cooling water, thus achieving a total thermal efficiency exceeding 50%. The major unabated flue gas emission with the installed equipment would have been approx.2,000 mg/Nm3 nitrogen oxides(NOx),565mg/Nm2 Sulfur Oxides(SOx), and Particulate Matter(PM)75 mg/Nm3, all ref.15% O2, dry. The contractual and obtained requirements are 150 mg/Nm3nitrogen oxides(NOx),112.5 mg/Nm3 Sulfur Oxides(SOx), and Particulate Matter (PM)50 mg/Nm3. The particulate matter is under all normal operational conditions much lower. The NOx reduction is obtained by a well established SCR principle with injection of Urea.
