Abstract:

Most of the traditional aging oil treatment methods have the disadvantages of high treatment cost, environmental pollution, low dehydration rate and large occupy area, which cannot meet the processing requirements of aging oil on offshore platforms. The model of rapid evaporation of aging oil film in vacuum environment is studied. It is shown that the higher the temperature and the smaller the flow rate is, the lower the moisture content of the aged oil is. For the aging oil with a water content of 10%, when the oil flow rate is 0.15 kg/min and the temperature reaches 80℃, the dehydration rate of the aging oil can reach 90%. After two cycles of dehydration, the moisture content of the aging oil is less than 0.5%, reaching the standard of crude oil external transportation.

Key words: aging oil, oil-water separation, vacuum, film, dehydration

摘要：

传统的老化油处理方法大多存在处理成本高、污染环境、脱水率低、设备占地面积大等缺点，不能满足海上平台老化油的处理要求。构建了真空环境下薄膜对老化油进行快速蒸发的模型。研究结果表明，温度越高、流量越小，老化油的含水率越低。对于含水率为10%的老化油，进油流量为0.15 kg/min、温度为80℃时，老化油脱水率可达90%。经过2次循环脱水后老化油的含水率低于0.5%，达到原油外输标准。
