Turbine Engine Lubricant Reclamation.

Abstract

A distillation and adsorption treatment for reclaiming used MIL-L-7808 turbine oils was investigated. A viable additive package was tested on different MIL-L-7808 type virgin base stocks. Fifteen used oils were analyzed by acid number, high performance liquid chromatography, and gas chromatography. A distillation process utilizing caustic (sodium hydroxide) pretreatment was developed on 500-mL and 13-litre scales. Adsorption treatment of distilled oils consisted of barium hydroxide monohydrate. A total of ten 15-25 gallon batches of oil were reclaimed/reformulated and MIL-L-7808H tested. Test results were generally good. However, none of the 10 batches completely passed all of the tests. An extensive screening procedure was found necessary to identify contaminated used oil samples. An engineering cost study is included.
