活性白土净化废汽轮机油

对废汽轮机油进行了再生研究。选用吸附能力比较强的活性白土为原料，采用实验室自制的经过引入无机高分子以后的改性活性白土为主要吸附剂，利用再生后油的透过率的变化，对再生条件进行了研究。再生条件：温度５５ ～６５ ℃；搅拌时间２０～３０ ｍｉｎ，根据汽轮机油劣化的程度不同，通过实验确定所加的吸附剂量一般为５％ ～２０ ％ 。再生后的油送检测单位检验，再生前后对比：水溶性酸碱ｐＨ４－９／５－８，酸值０－０５９６／０－００５７ ｍｇ ＫＯＨ／ｇ，破乳化度（ 搅拌法）５０／１ ｍｉｎ。结论：再生效果较好，达到新油标准。再生后废油的回收率可达８５％ 左右。

Purification of Waste Turbine Oil by Activated White Clay

To research into the regeneration of waste oil,activated white clay having stronger adsorbing capacity was selected as raw material.In order to increase its adsorbability,the modified activated white clay made by introducing inorganic high molecule was adopted as the chief adsorbent.Using the transmissivity change of regenerated oil,the regeneration conditions were investigated.Thus,at temperature 55-65 ℃,mixing time 20-30 min,the adsorbent dosage was determined by experiment,usually 5%-20% according to the quality of waste oil.Regenerated oil was tested by the testing works.Comparing with the waste oil,after regeneration,liquefacient acid and alkali pH changed from 4 9 to 5 8,acid value from 0 0596 to 0 0057 mgKOH/g,and broken emulsifiability(stirring method)from 50 to 1min.Therefore the regenerated oil was better,reaching the standard of new oil(testing report attached).Recovery of the waste oil reached about 85%.
