Abstract

The invention relates to a regeneration refining process for waste lubricating oil. A raw material tank is connected with a raw material pump, the outlet of the raw material pump is connected with thelower part of a primary extraction tower after passing through a raw material heat exchanger; the tower top of the primary extraction tower is connected with the lower part of a secondary extractiontower, the tower top of the secondary extraction tower is connected with a solvent settling tank, the solvent settling tank is connected with a first heating furnace, the first heating furnace is connected with the upper part of a lubricating oil flash tower, the bottom of the lubricating oil flash tower is connected with a lubricating oil flash bottom pump, an outlet of the lubricating oil flashbottom pump is connected with the upper part of a lubricating oil stripping tower, the bottom of the lubricating oil stripping tower is connected with a lubricating oil stripping bottom pump, the outlet of the lubricating oil stripping bottom pump is coupled and connected with an extract secondary evaporation bottom heat exchanger, the extract secondary evaporation bottom heat exchanger is coupledand connected with the raw material heat exchanger through a pipeline, and the raw material heat exchanger is connected with a finished product tank. According to the regeneration refining process, colloid and asphaltene in the waste lubricating oil can be effectively removed, the process flow is continuously carried out, and the energy consumption is low.

Description

technical field [0001] The invention relates to a regeneration and refining process for waste lubricating oil, belonging to the technical field of lubricating oil separation. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. With the development of the machinery industry, the demand for lubricating oil is increasing, and the waste lubricating oil produced in the machinery industry is also increasing. If the waste lubricating oil is discarded directly, it will cause serious environmental problems. Using conventional filtration, Adsorption or simple distillation methods are used to recover waste lubricating oil. The recovered lubricating oil often contains some impurities such as colloids and asphaltene, so that th...
