The steam generated by heating to 00~4-00℃ is 40~7.5
In Broceze, which recovers distillate oil by cooling it to ℃, the distillate contains gummy and resinous substances that are thought to be due to the oxidation, decomposition, and polymerization of heavy oil and additives, and the recovery plant They deposit in piping systems, pumps, etc., not only impeding the smooth operation of the plant, but also causing a decline in the quality of distillate oil. Conventionally, product oils are filtered using R-cloth filters with a pore size of 3 μm, but most of the gum or resinous substances contained in distilled oil immediately after distillation exist as fine particles of 1 μm or less. Therefore, filtration and separation using sawcloth was insufficient.

なる各種の添加剤が混入されている。Waste oil generated from automobile repair shops, gas stations, machine shops, etc. is a mixture of various oils such as engine oil, machine oil, gear oil 1, spindle oil, and washing oil. These various lubricating oils contain thioethers, sulfonates, sulfinates, oxycarboxylic compounds, etc., such as acid monoxide inhibitors, detergents, viscosity index improvers, rust inhibitors, antifoaming agents, and emulsifiers, depending on the purpose. Various additives such as 1 ether and carbonyl compounds are mixed in.

じられていた。Most of these additives decompose at 150 to 400°C to form hydrogen sulfide, mercaptans, sulfates, etc., which are contained in the gas side or distillation residue and are separated from the distillate. However, the distillate oil contains gummy or resinous substances that are thought to be produced by the decomposition, oxidation, and polymerization of hydrocarbons or the decomposition, oxidation, and polymerization of the additives. These gums or resins are used in piping systems, pulp,
Gradually adheres to and accumulates on pumps, etc., obstructing fluid flow and impairing the operability of pulp and pumps. Furthermore, when distillate oil is used as fuel oil, gum or resinous substances not only gradually settle on the bottom of the fuel tank, but also adhere to the burner nozzle and impair combustibility. No countermeasures were taken at the plant to deal with these problems, and the distillate oil was left unprotected.

た。However, most of the gummy or resinous substances present in distilled oil are fine particles of 1 μm or less in the distilled oil immediately after distillation, and cannot be completely removed by the commonly used cloth with a pore size of about 3 μm. In addition, since the gum or resinous substance in the distillate oil is viscous and cohesive, there is a problem in that it promotes clogging of the cloth and significantly shortens the life of the cloth.
本発明は、これら留出油中のガム質あるいは樹脂質のよ
うな粘稠性物質を簡単に除去し、上述したような欠点を
生じさせない廃油の回収処理方法を提供しようとするも
のである。The present invention aims to provide a waste oil recovery and treatment method that easily removes viscous substances such as gum or resin from these distillate oils and does not cause the above-mentioned drawbacks.
本発明は廃油を減圧下で加熱・蒸留して燃料油又は潤滑
油原料を回収するに当たって、留出油に多価アルコール
を添加、共存させたのち、留出油を遠心分離処理するこ
とを特徴とする廃油の回収処理方法である。The present invention is characterized in that when waste oil is heated and distilled under reduced pressure to recover fuel oil or lubricating oil raw materials, a polyhydric alcohol is added to the distillate to make it coexist, and then the distillate is centrifuged. This is a method for collecting and treating waste oil.
本発明は、パラフィン基、ナフテン基、オレフィン基の

適用される。The present invention can be applied to any of paraffin-based, naphthenic-based, and olefin-based waste oils, but is particularly applicable to paraffin base oils. The present invention uses 80 T of the above waste oil.
Applies to distillate oils distilled at temperatures below orr and below 560°C.

い。The polyhydric alcohol (one or more of ethylene glycol, diethylene glycol, and glycerin) added to the distillate, which is a feature of the present invention, is added to the distillate at a level higher than its solubility (usually o, o s wt%). be done. Thereafter, the polyhydric alcohol in which the gum or resin has been dissolved is separated by centrifugation and liquid cyclone. The polyhydric alcohol may be added at any temperature range below its decomposition temperature.

め容易に分離される。Gummy and resinous substances in the distillate oil are selectively dissolved and extracted by a small amount of added polyhydric alcohol, and are granulated, precipitated, and separated. In addition, the sediment is less viscous than gum or resin, so it does not adhere to or accumulate on piping systems, pulp, pumps, etc., and has a higher specific gravity than distillate oil, so it is easier to use. separated into
