以室内试验数据为依据 ,对曙一区超稠油在热电厂及集中处理站进行了热化学沉降脱水的现场应用试验。现场试验结果表明 ,超稠油含水 18%～ 40 % ,加入LH— 3破乳剂 5 0 0～ 70 0mg/L ,脱水温度为 84～ 90℃ ,沉降时间大于 96h ,可使净化油含水达到 3%以下 ,满足了生产的要求 Based on the laboratory test data, a field application test of thermochemical sedimentation and dehydration was carried out on the super heavy oil in Shu 1 area in thermal power plants and centralized treatment stations. The field test results show that the super heavy oil contains 18% ~ 40% water, the addition of LH- 3 demulsifier 500 ~ 70 0mg / L, the dehydration temperature is 84 ~ 90 ℃, settling time is more than 96h, % Below, to meet the production requirements
