Abstract: A method and system generate steam for SAGD operation wherein steam generator blowdown water is acidified, cooled and clarified before reuse. Acid Clarification Treatment, or “ACT”, mitigates organic fouling in Once-Through Stream Generators. Lab tests quantitatively and qualitatively show that ACT reduces Total organic carbon (TOC) and ‘bad actors’ TOC, respectively, in blowdown streams.

Abstract: Methods and systems relate to generating steam from water that contains dissolved organic compounds. The methods mix a polymerization inhibitor with the water prior to feeding the water into a steam generator. The polymerization inhibitor limits coupling of the dissolved organics under boiler conditions to mitigate fouling issues within the boiler.
