Summary
-
1.
Light phenol-treated turbine oil from sulfur petroleums, subjected to hydro-afterpurification, has physicochemical indices (particularly the demulsification velocity) superior to those of the oil obtained by hydro-afterpurification with fuller's earth.
-
2.
Tests onhydrorefined turbine oil containing 0.2%topanol in power station turbines showed that this oil has practically the same operational properties as selectively treated oil afterpurified with fuller's earth (and also containing 0.2% topanol).
-
3.
Hydro-afterpurification of phenol-treated turbine oil is technologically superior to contact afterpurification with fuller's earth, and the technical-economic indices of this process are also superior.
