Description
Technical field
The present invention relates to a kind of waste mineral oil comprehensive utilization device, particularly in a kind of waste mineral oil deep processing, dehydrated sulfur takes off technology application.
Background technology
In oil production, processing and oil product use procedure, can produce a large amount of waste mineral oils, oils meeting contaminated land itself, waters, impurities has larger harm to human health and ecotope.Along with the continuous increase of domestic high-sulphur heavy fuel oil consumption, in the shop sump oil of the waste mineral oil recovery especially waterborne of reclaiming, sulphur content is high, water content is large, and oil-water emulsion state is serious.Have that a patent No. is 96119130.9, name is called the patent of invention of " waste oil regeneration carclazyte high-temperature refined craft and device ", disclose technique and device that a kind of waste oil regeneration is neutral oil and bright stock, its technical process is: first by waste oil, carclazyte, vapour three-phase mixed transferring, in tube furnace circulation refining and distilling tower, be heated to 300 DEG C, flash off moisture, solar oil; Then oil with soil proceeds to second tube furnace circulation refining and distilling tower, and oil, soil, vapour three-phase heat and be refined to 400 DEG C under violent turbulent state; Last heat exchange is filtered after being cooled to 130 DEG C, obtains neutral oil and bright stock.Though the ripe application of this technology, because current similar waste mineral oil treatment unit only can process low sulfur-bearing waste mineral oil, costs and poor dehydration results, without desulfurization equipment, cannot carry out deep processing utilization, so need further improvement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of comprehensive utilization device processing high sulfur-bearing waste mineral oil for above-mentioned prior art present situation.
The present invention's adopted technical scheme that solves the problem is: select the operational path device based on dry vacuum distillation, comprising: electro-dewatering tank, electrical desalter, flashing tower, condensate cooler, process furnace, vacuum distillation tower are formed by connecting by pump, pipeline and valve.
As improvement, electrical desalter is set to secondary or plural serial stage uses, to adapt to the feature of waste mineral oil High water cut height saliferous.
Improve again, the outlet of condensate cooler is provided with liquid film alkali cleaning reactor and liquid film sweetening reaction device, fiber liquid film alkali cleaning and mercaptan removal process are carried out respectively to flash distillation overhead oil (chemical industry light oil), the content of hydrogen sulfide and mercaptan sulfur in product can be reduced, improve product quality.
Improve, vacuum distillation tower top is provided with vacuum jet, Water-ring vacuum compressor, hypergravity machine, is connected successively by pipe valve, and hypergravity machine pneumatic outlet is connected with process furnace by pipeline again.Select hypergravity machine depriving hydrogen sulphide technology, the cracking noncondensable gas produced in vacuum distillation tower still-process, after hypergravity machine desulfurization, hydrogen sulfide content is reduced greatly, the requirement being used as furnace fuel can be met.
Further improvement, discharge on line at the sewage of electrical desalter and set up except trap for oil, when electrical desalter sewer oleaginousness is excessive, this facility can play sump oil interception, solves the Crude Desalting System problem that draining oil-containing exceeds standard when fluctuation of service.
Accompanying drawing explanation
Fig. 1 is the process structure figure of the embodiment of the present invention;
Concrete enforcement
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1, waste mineral oil comprehensive utilization device designed by the present invention comprises: electro-dewatering tank 1, electrical desalter 2, flashing tower 3, condensate cooler 4, process furnace 7, vacuum distillation tower is formed by connecting by pipeline and valve by pump 8, electrical desalter 2 is set to secondary or plural serial stage uses, the outlet of condensate cooler 4 is provided with liquid film alkali cleaning reactor 5 and liquid film sweetening reaction device 6, vacuum distillation tower 8 top is provided with vacuum jet 9, Water-ring vacuum compressor 10, hypergravity machine 11, connected by pipe valve successively, hypergravity machine 11 pneumatic outlet is connected with process furnace 7 by pipeline.Discharge on line at the sewage of electrical desalter 2 and be provided with except trap for oil 12.
Concrete treatment scheme is as follows: waste mineral oil enters electro-dewatering tank 1 and I and II electrical desalter 2 after a heat exchange, then enter flashing tower 3 through secondary heat exchange, the lightweight cracked oil distillated from flash distillation tower top enters liquid film alkali cleaning reactor 5 after condensate cooler 4 cools and liquid film sweetening reaction device 6 carries out desulfurization process.Oil at the bottom of flashing tower enters process furnace 7, enters vacuum distillation tower 8 after heating, and vacuum distillation tower 8 side line oil is middle matter cracking stock oil, is asphalt stock oil at the bottom of tower.The cracking noncondensable gas that flashing tower 3 end oil produces when vacuum furnace heats, extract out through condensate cooler 4 from Top of Vacuum Tower through vacuum jet 9, by Water-ring vacuum compressor 10, pressure-raising laggard enter hypergravity machine 11 depriving hydrogen sulphide, after desulfurization, gas is delivered to process furnace 7 and is burnt.
By adopting above-mentioned Technology in dehydration desulfurization, the ability of device is possessed all kinds of waste mineral oil of deep processing process, the production of device achieve safety, environmental protection, flexibly, efficient, and higher economic benefit can be obtained.
