Development of Eco-friendly "AO-Industrial Oil" Using AO-Oil Stabilizing Additives

Abstract

  This industrial oil is based on "AO-oil," the stabilization technology of watch lubricating oil. The plant-derived hydrocarbon is applied to this industrial oil instead of the synthetic hydrocarbon PAO. The plant-derived substance is also adopted to the functional additives which are necessary to industrial oil. Cyclic regeneration is enabled by combining the adsorption and distillation process. 95% of this “AO-industrial oil” is composed of the base oil. At least 3.1 kg of CO₂ is absorbed to produce 1 kg of plant-derived hydrocarbon base oil. On the other hand, about 2.7 kg of CO₂ is generated for the synthesis, storage and transportation of the oil. As a result, -0.35kg of CO₂ can be accumulated since the amount of CO₂ absorbed to produce 1kg of base oil exceeds it generated in the production sequences. Therefore, a greater environmental effect can be expected by cyclic regeneration of this plant-derived AO-industrial oil.
