Abstract
Provided is a hydrogenating and regenerating technology for complete hydrogenation type used lubricating oil. The hydrogenating and regenerating technology comprises the following steps: carrying out the extraction and reextraction operation on obtained used lubricating oil, and removing impurities and water in the used lubricating oil; adding the obtained lubricating oil and fresh hydrogen into a heating furnace to heat, and then adding the heated lubricating oil and the heated fresh hydrogen into a hydrogenating reactor; obtaining a high molecular chemical compound and a low molecular chemical compound through carrying out extraction separation on a hydrogenated material; using the obtained high molecular chemical compound as the raw material after the desulfuration is carried out on high molecular chemical compound through a devulcanizer; carrying out fractionating on the obtained low molecular chemical compound through a fractionating tower, and obtaining white oil and lubricant base oil. The hydrogenating and regenerating technology has the advantages that the technology is simple, the operation is convenient, and the recycling of the used lubricating oil is effective.
Description
Technical field
The invention belongs to process for regeneration of waste lubricating oil, be specially complete hydrogenation type waste lubricant oil by hydrogenation reclaiming process.
Background technology
At present, need to change new oil in time after lubrication system works for some time of mechanical means, to ensure the normal work of oiling system, but the waste lubricating oil changed is mostly as offal treatment, causes the very large wasting of resources, simultaneously
Summary of the invention
The object of the present invention is to provide complete hydrogenation type waste lubricant oil by hydrogenation reclaiming process, solve the shortcoming that existing waste lubricating oil can not get Appropriate application.
The present invention realizes by the following technical solutions:
Complete hydrogenation type waste lubricant oil by hydrogenation reclaiming process, comprises the following steps:
The first step: by the waste lubricating oil that obtains by extraction and back-extraction extract operation, the impurity in removing waste lubricating oil and moisture;
Second step: the lubricating oil obtained and new hydrogen are joined and joins in hydrogenator after heating in process furnace;
3rd step: the material after hydrogenation reaction is obtained macromolecular compound and low molecular compound by extracting and separating;
4th step: using the macromolecular compound obtained by using as raw material after digester desulfurization;
5th step: the low molecular compound obtained is carried out fractionation by separation column, obtains white oil material and lubricant base respectively.
Beneficial effect: present invention process is simple, easy to use, can effective recycling waste lubricating oil.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1, the process flow sheet of complete hydrogenation type waste lubricant oil by hydrogenation reclaiming process, complete hydrogenation type waste lubricant oil by hydrogenation reclaiming process, comprises the following steps: by the waste lubricating oil that obtains by extraction and back-extraction extract operation, the impurity in removing waste lubricating oil and moisture; The lubricating oil obtained and new hydrogen are joined and joins in hydrogenator after heating in process furnace; Material after hydrogenation reaction is obtained macromolecular compound and low molecular compound by extracting and separating; Using the macromolecular compound obtained by using as raw material after digester desulfurization; The low molecular compound obtained is carried out fractionation by separation column, obtains white oil material and lubricant base respectively.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention; the technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
