  • 摘要: 针对罐底油泥水洗过程中存在的油相与固相分离难度大、回收的油分中含固率与含水率较高2个关键问题，研究了以“球磨+浮选”为核心的联合工艺的处理效果。对球磨和浮选工艺参数进行优化后，确定球磨段的最优处理条件为球磨温度45 ℃，液固比3∶1，球磨处理时间30 min，球磨药剂用量0.8%；浮选段的最优处理条件为浮选温度55 ℃、液固比4∶1、浮选时间35 min、浮选药剂用量0.6%。结果表明：在最优条件下，处理后罐底油泥的固体出料含油率可降低到0.8%，达到了 SY/T 7301-2016中规定的处理处置要求；处理过程中得到的原油经过油品纯化后，含水率与含固率均低于0.5%，可在炼厂进行回收利用。以“球磨+浮选”为核心的联合工艺较好地解决了罐底油泥在水洗过程中暴露出来的2个问题，为罐底油泥的无害化、资源化处理提供了参考。
    Abstract: During treating oily sludge of tank bottom by water-based extraction, two key problems, such as difficult separation of oil and solid phases and high water and solid contents of the recovered oil, need to be solved. A combined process based on the core technology of “ball mill + flotation” was used to study its treating effect for this oily sludge. After optimizing the process parameters of ball milling and flotation, the optimal operational conditions at ball mill stage were determined as follows: 45 ℃, the liquid-solid ratio of 3∶1, 30 min treating duration and the ball mill dosage of 0.8%. The optimal operational conditions at flotation stage were determined as follows: 55 ℃, the liquid-solid ratio of 4∶1, 35 min treating duration and the flotation reagent dosage of 0.6%. Under the optimal conditions, the oil content in solid discharge of treated oily sludge of tank bottom could be reduced to 0.8%, which could meet the treatment and disposal requirements stipulated in SY/T 7301-2016. Both water and solid contents in the purified oil were lower than 0.5%, which could be delivered to the refinery for recycling. The combined process based on the core technology of “ball mill + flotation” can solve the two key problems during treating oily sludge of tank bottom by water-based extraction, and provides a reference for the harmless and resource utilization of oily sludge of tank bottom.
