Waste mineral oil catalytic cracking comprehensive utilization system and processing process thereof

Abstract

The invention relates to a waste mineral oil catalytic cracking comprehensive utilization system and a processing process thereof. The comprehensive utilization system comprises a raw material pretreating system, a raw oil preheating system, a flashing catalytic cracking system, a solvent refining system, a finished product oil storage system, a heating system, a residual oil subsequent processing and treating system and a waste water treating system. The processing process comprises the steps of pretreating the raw materials, preheating the raw oil, performing flashing catalytic cracking and performing solvent refining. According to the processing process provided by the invention, a fuel oil product can be recovered, impurities and water can be removed from waste mineral oil, the problem that the waste mineral oil is difficult to treat is solved, waste water and waste gas are comprehensively utilized in the whole process, no waste is discharged, the problem of environmental pollution is avoided, recycling economy is realized, energy consumption is reduced, and the application prospect is wide. The final refined oil product has clarified and transparent color and is widely applied.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of catalytic cracking of waste mineral oil, in particular to a comprehensive utilization system of catalytic cracking of waste mineral oil and a processing technology thereof. Background technique [0002] Waste mineral oil is the oil that is replaced when the original physical and chemical properties are changed due to impurity pollution, oxidation and heat, and it cannot continue to be used. Waste mineral oil contains impurities and moisture such as metal scraps, dust, sand, and fibrous substances. Waste mineral oil is widely produced and exists in various fields of industrial production. For example, power plants replace a large amount of steam turbine oil and gear oil every six months to two years; metallurgical industries discharge mechanical oil and anti-wear hydraulic oil that have lost their effectiveness; auto repair shops replace them every day Vehicle gear oil and gas...
