The invention discloses a solvent dewaxing method for lubricating oil production. A dewaxing device comprises a concrete foundation, and an additive stirring kettle, a cooling kettle and a paraffin filtering kettle are fixedly mounted on the upper surface of the concrete foundation in sequence from left to right. The invention further provides a using method of the solvent dewaxing method for lubricating oil production. The method comprises the following steps that S1, lubricating oil to be dewaxed is injected into an additive stirring kettle from a feeding pipe, an adding solvent is injectedinto an adding pipe, a stirring motor is controlled by a control panel to work, and stirring fan blades are driven by the stirring motor to stir the solvent and the lubricating oil to be dewaxed. According to the dewaxing device for lubricating oil production, the stirring motor and the stirring fan blades are arranged, the stirring motor is used for driving the stirring fan blades to stir lubricating oil and an added solvent in the additive stirring kettle, and due to the fact that the stirring fan blades are provided with the round holes, when a mixed liquid is blocked by the stirring fan blades, the mixed liquid can flow out of the small holes in the stirring fan blades, and stirring is more sufficient.
Description
technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to a solvent dewaxing method for lubricating oil production. Background technique [0002] Solvent dewaxing is an important method of refining petroleum products. The raw material of lubricating oil is diluted and frozen by solvent to crystallize the wax in it, thereby lowering the freezing point of lubricating oil. Solvent deasphalting, solvent refining, solvent dewaxing and hydrofinishing processes to produce lube base oils and paraffins. [0003] The traditional lubricating oil dewaxing equipment cannot stir the lubricating oil well when adding solvent, resulting in incomplete dilution, which will cause incomplete filtration during filtration, and the precipitated wax crystals will block the mesh on the filter net , causing problems such as poor filtering effect. Contents of the invention [0004] The object of the present invention is to provide a solvent ...
