SOTU重质污油处理技术的应用及分析

SOTU技术是一种新型的重污油处理技术，采用多级循环处理工艺。污油经过预处理部分的超声波破乳组件、次高频振动组件和高能电子束组件增核破乳后，经一级分离去除固体杂质、二级分离去除水分后，达到污油进装置或者进入原油罐回炼的目的。塔河重质污油的油水密度差小，固体杂质含量较高，传统工艺技术处理难度大，经SOTU技术处理后，污油含水率（w）为1.45%，处理后污水的含油量为49.3 mg/L，优于污油含水率（w）小于3.0%、处理后污水含油小于150 mg/L的目标。

APPLICATION AND ANALYSIS OF HEAVY WASTE OIL TREATMENT TECHNOLOGY SOTU

SOTU (Slop Oil Treatment Unit) is a new heavy dirty oil treatment technology, which adopts a multi-stage cycle treatment process. After demulsification and nucleation by ultrasonic demulsification, sub-high-frequency vibration and high-energy electron beam in the pretreatment part, the solid impurities are removed in the first stage separation, and water is removed in the second stage separation, then the waste oil is transported to the device or returned to the original tank for refining. The density difference of heavy dirty oil and water of Tahe Refining and Chemical Co. is small, and the content of solid impurity is high, which is difficult to deal with by traditional process. After treatment by SOTU, the water content of dirty oil is 1.45%(w), and the oil content of treated sewage is 49.3 mg/L, which is better than the target that the water content of dirty oil is less than 3.0%, and the oil content of treated sewage is less than 150 mg/L.
