Embodiment Construction

[0015] The present invention relates to a method for lowering the cloud point of a base oil having a high saturate / paraffin content below 0°C, wherein said method comprises subjecting said base oil to a cloud point lowering step, said The cloud point lowering step comprises (a) adding said base oil to a solvent mixture to obtain a solvent treated mixture, wherein the solvent mixture comprises a paraffinic naphtha fraction and a co-solvent; and (b) subjecting the solvent treated mixture to a solvent dewaxing step .

[0016] For the purposes of the present invention, a base oil having a high saturate / paraffin content may be a base oil having a saturate / paraffin content exceeding 90%, such as Group II and Group III base oils (according to API classification). Suitably, a base oil having a high saturate / paraffin content may also be a base oil having a saturate / paraffin content exceeding 95%. Suitably, the base oil having a high saturate / paraffin content may also be a base oil hav...

Abstract

The present invention relates to a method for reducing the cloud point of base oil with high saturates / paraffinic content to below 0 DEG C, wherein the method comprises subjecting said base oil to acloud point reduction step comprising adding said base oil to a solvent mixture, wherein the solvent mixture comprises a paraffinic naphtha fraction and a co-solvent to obtain a solvent treatment mixture; and subjecting the solvent treatment mixture to a solvent de-waxing step.

Description

technical field [0001] The present invention relates to a method for lowering the cloud point of base oils with a high paraffin content. Background technique [0002] The American Petroleum Institute (API) provides a generally accepted method of classifying base oils according to which base oils are divided into five groups according to their sulfur content, saturates / paraffins content and according to their viscosity index. Group I base oils contain greater than 0.03% sulfur, have a saturate / paraffin content of less than 90%, and have a viscosity index in the range of 80 to 120. In contrast, Group II base oils contain less than 0.03% sulfur, have a saturate / paraffin content of greater than 90%, and have a viscosity index in the range of 80 to 120. On the other hand, a Group III base oil has a viscosity index greater than 120, even though its sulfur saturate / paraffin content is in the same range as a Group II base oil. A further difference between Group I, Group II, and Gr...
