Through the analysis on the production process of L-TSA oil, the factors of affecting the demulsibility of steam turbine oil are sought from the base oil, additive and blending process.

通过对L-TSA油品的调合过程进行分析，分别从基础油、添加剂和调合工艺过程三方面探寻制约汽轮机油抗乳化性能提高的原因，研究发现基础油的白土吸附深度、水分含量对基础油本身的破乳化性能影响显著，从而导致用其调制的汽轮机油抗乳化性出现相应变化；而添加剂中金属减活剂和防锈剂的加剂量对成品油的抗乳化性能有一定的影响。
