Problems solved by technology

Compared with the existing technology, the process is simple, the operation is flexible, and there is no pollution. The quality indicators of the lubricating oil base oil produced all meet the requirements of the general base oil standard for lubricating oil, and can be used to prepare various lubricating oil products; however, although the patented technology experiment According to the data, it can achieve very good indicators such as chroma, but it must go through the hydrogenation step to achieve excellent lubricating oil base oil indicators, which makes the treatment cost of waste lubricating oil higher, while waste lubricating oil without hydrogenation cannot Achieving valid base oil standards

Embodiment 1

[0073] figure 1 It is the process equipment flowchart of the first embodiment of the present invention. according to figure 1 In the shown equipment, the waste lubricating oil of the present invention can implement the following process. According to the description in the specification and the claimed scheme, the connection relationship of the equipment can also be adjusted accordingly, omitted or added.

[0074] Step a) is carried out first. The stored waste lubricating oil raw material is introduced into the raw material buffer tank (not shown in the figure), pressurized by the raw material pump, and after exchanging heat with the heat from the atmospheric pressure evaporator, it is connected with the distillation reagent delivery pipeline The basic reagents are mixed and mixed, and then transported into the first reactor 1, and the reaction temperature of 1 in the first reactor is controlled to be 80°C;

[0075] In this embodiment, the first reactor 1 adopts a plug flow...

Embodiment 2

[0085] figure 1 with figure 2 The combination of is used as embodiment 2 of the present invention. That is, Example 2 implements figure 1 shown in the first paragraph processing, and figure 2 shown in the second paragraph processing.

[0086] The process of the first stage of treatment in embodiment 2 is the same as that in embodiment 1, and will not be repeated here. Further, when an extraction side line is set in the middle of the first decompression evaporator 4 to extract the first stage base oil through the heat exchanger 9 and the condenser 8, the first stage base oil at the outlet is transported to figure 2 In the transfer line of the second reactor 21 (i.e., step d is carried out). Thereafter, the first stage base oil is used as the raw material for the second stage treatment, and the following flow process is carried out:

[0087] Step e), providing the obtained Stage I base oil to the second reactor 21; and, before being supplied to the second reactor, provi...

Embodiment 3

[0097] image 3 and refer to figure 1 It is the third embodiment of the technical solution of the present invention. In this embodiment, four side-drawn oil products are used in the second stage of treatment, so that base oils with different distillation ranges and viscosities can be obtained, and the physical and chemical indicators of the oil products are further optimized. Specifically, see image 3 , when the technique of embodiment 2 was carried out to decompression evaporation, from the first section base oil extraction pipeline 211, the second section base oil extraction pipeline 212, the third section base oil extraction pipeline 213; the fourth section base oil extraction pipeline 214 The first-stage base oil, the second-stage base oil, the third-stage base oil and the fourth-stage base oil were extracted respectively.

[0098] The physical and chemical indicators obtained are as follows:

Abstract

The invention provides a continuous waste lubricating oil steam treatment method. The method comprises the following steps that 1, a raw material containing waste lubricating oil is supplied to a reactor; 2, the raw material passing through the reactor enters a normal pressure evaporator for performing the evaporation treatment technology to obtain a top light oil component, water and a bottom oilcomponent; 3, the bottom oil component is conveyed into a decompression evaporator, reduced pressure distillation is performed in the decompression evaporator, and base oil is obtained in the decompression evaporator; 4, the base oil is pumped out and stored, or the base oil is conveyed to the follow-up technologic step; according to the method, the capability of continuously producing and processing waste lubricating oil is effectively improved, and no complex chemical substances or additives harmful to environment or oil components need to be added; in the preferential scheme, the method can improve the chroma value and other physicochemical indexes of oil products.

Description

technical field [0001] The invention relates to a process for treating and separating waste lubricating oil and a device for implementing the process, in particular to a continuous distillation treatment method for waste lubricating oil. Background technique [0002] In industrial production and use, lubricating oil is subjected to oxidation, thermal decomposition and impurity pollution in various machinery and equipment, and its physical and chemical properties reach the respective oil change indicators. The replaced oil is collectively called waste lubricating oil. Therefore, waste lubricating oil belongs to hazardous waste that is scrapped, polluted, high-temperature oxidized and has lost its original properties; on the other hand, waste lubricating oil is also a class of waste mineral oil with high utilization value. With the continuous deepening of the waste lubricating oil treatment industry, how to more effectively and quickly reach the index of waste lubricating oil ...
