Abstract

The invention relates to an oil purification process, in particular to a purification process aiming to pyrolysis oil of waste rubbers and waste plastics and waste oil under normal temperature and normal pressure. The process comprises the following steps: a purifying agent containing water, flocculant and raw oil are added into an emulsion tank; the purifying agent and the raw oil are mixed to cause the purifying agent to emulsify the raw oil; and obtained emulsified oil enters separation equipment to separate oil and non-oil substances, and pure oil is obtained. In the whole treating process, a method for oil purification by adopting high-temperature distillation, strong acid and strong alkali in the prior art is changed, thereby oil loss caused by oil carbonization and coking because of high temperature and generation of a large amount of acid residues and alkaline residues are avoided to improve the yield and the safety performance of purified oil, the environmental pollution is avoided at the same time, and the energy consumption is lowered.

Description

technical field

[0001] The invention relates to an oil purification process, in particular to a purification process for pyrolysis oil and waste oil by using non-chemical means under normal temperature and pressure. Background technique

[0002] At present, the annual output of various waste oils in my country is about 5 million tons, and a large amount of cracked oil products are produced at the same time. These waste or cracked oil products contain a large amount of solid impurities such as sulfides, chlorides and various impurities and asphalt. The existence of these impurities greatly reduces the quality of the oil, and at the same time affects the reprocessing of the oil, which greatly reduces the added value of the oil. If these substances are directly discharged or used without treatment, the waste gas produced It will also cause huge pollution to the environment.

[0003] There are many ways in the existing waste oil treatment process, but the steps generally include:...
