Lubricating mineral base oils are normally extracted from lube-oil cuts with furfural solvent. Aromatic content in the raffinate phase from extraction process is an essential parameter that affects the quality of the lubricating base-oils. For determination of aromatic content by the usual ASTM D3238 method, density, refractive index and molecular weight of the raffinate are required. In this work,...
Industrial processes are the most energy consuming processes in the world. Modification of these processes helps us with controlling the consumption of energy and minimizing energy loss. Changing raw materials is one of the ways through which we can optimize industrial processes. In this paper, a new solvent mixture (furfural+a co-solvent) was used for the extraction of lubricating base oil from lube-oil...
