TREATMENT OF OTSG BLOWDOWN |
| 摘要 |
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. |

1. A method of treating once through steam generator (OTSG) blowdown water for reuse, said method comprising:
a) providing OTSG blowdown water; b) acidifying said OTSG blowdown water to pH 8 or lower; c) cooling said OTSG blowdown water to 30-40° C.; d) settling precipitants out of said OTSG blowdown water for at least 12 hours to produce an acid clarified blowdown water; and e) reusing said acid clarified blowdown water. |
