Tupras Izmit Refinery

Babcock Boilers = 5 Design steam = 120 tons each Total steam = 600 tons per hour Typical steam = 300 – 400 tons/hr Operational pressure = 42 bar Steam temperature = 412°C Fuel used = HFO Feed water deaerated = 150°C Turbine = 4 x 14 MW Condensate return = approx. 50 % Make-up = Demineralized HELAMIN® since = July 2000

Previous water treatment program utilized:

Ammonia, Hydrazine & Phosphate

Commodity treatment limitations:

• Localized metal wastage of the steam and condensate sections of plant.
• Corrosion in the feed section of plant, with deposition of corrosion oxides in the deaerator.
• Corrosion, erosion and fouling of the superheater and steam turbine blading and condensing section of the turbine.
• Deposition of corrosion products in the condensate tank, including under deposit corrosion of the condensate tank.
• Excessive boiler fouling with magnetite leading to short term overheating and tube ruptures

HELAMIN® achieved benefits

• Reduced corrosion in all steam water sections of approx. 4,5 x
• Slow and progressive cleaning of fouled boiler heat transfer surfaces, confirmed by the analytical measurement of residual phosphate in the boilers despite termination of this commodity program some 2 months prior.
• Ease of application, no operator involvement with mixing and handling of chemicals.
• No exposure to toxic hydrazine and termination of environmental abuse.

Comparative analysis

The continued measurement of residual boiler phosphate, despite termination of the commodity treatment some months previous – confirming the HELAMIN? cleaning action and liberation of heat transfer multi-component oxide foulants

Please note the reduced corrosion of steam and condensate sections
