Abstract
The invention discloses a process for extracting diesel oil from waste mineral oil, and belongs to the technical field of petrochemical industry. In the process, a waste oil chemical analysis method is adopted. Waste oil with large molecular weight is added into special refining equipment; and kerosene, the diesel oil, gasoline and residual oil are effectively separated out by waste oil treatment, distillation, gasification and condensation processes. The process for extracting the diesel oil from the waste mineral oil has the advantages of strict criterion, high degree of automation, high refining efficiency and low cost, is easy and convenient to operate and is practicable, safe and reliable; and an obtained base oil product accords with the national standard.
Description
Technical field
The invention belongs to the petrochemical technology field, relate to a kind of waste oil and refine the base oil method.
Background technology
It mainly is based on the local method freshening that the waste oil that utilizes various machineries such as automobile, tractor, train, steamer, transformer, wheel box, hydraulic machinery to change refines on the technology market of gasoline, diesel oil, kerosene; Its technology mainly is that a pot type is refined, and lacks gasification condensation operation, is heated after directly go out diesel oil after the condenser condenses by reactor; There is not the strict process step, technology is simply elementary, control of process parameters can not get guaranteeing, critical temperature can not effectively be controlled, operation control is not rigorous, oil yield and production efficiency are low, and product mixture, non-alkane material that output is come are more, cause the oil quality index of producing not reach the national standard requirement.
Processes well known is the refining process at the oil molecular chain, and waste oil mainly is the mineral oil that extract from oil, is multiple hydrocarbon polymer of containing of a complexity---be called " hydro carbons ", and the mixture of element such as oxygen, nitrogen, sulphur.When abstracting from crude oil useful oil, removed wherein to the oily deleterious hydrocarbon compound of reasonable usefulness---be wax, pitch, colloid, unstable component and low-viscosity index component etc.; As seen, most of waste oil is the petroleum products of based on very high purity.Waste oil in use generates various deterioration by oxidation things (as carboxylic acid, alcohol acid and condenses thereof, organic acid salt because of being subjected to oxygenizement, bituminous matter, lime-ash, greasy filth etc.), and bring part dust impurity and moisture etc. into because of carrying secretly or leaking, the quality of oil is reduced, replaced out by new oil until reaching the changing oil standard of oil plant regulation, the kerosene of being changed is called as waste oil.Because waste oil (going bad of oil) just waste oil part hydro carbons (accounting for 1～25%) has taken place rotten, rest part hydrocarbon composition (accounting for 75～99%) is still good viscosity carrier, as long as remove rotten thing and impurity, the base oil that can conform to quality requirements waste oil regeneration one-tenth just.Therefore, waste oil is a kind of fabulous petroleum resources of reproducible utilization.
Summary of the invention
The purpose of this invention is to provide the oily diesel oil technology of refining of a kind of mineral waste, refine, lack gasification condensation operation, heat after directly go out diesel oil after the condenser condenses by reactor to solve prior art one pot type; Problems such as do not have the strict process step, technology is simply elementary, and control of process parameters can not get assurance, and critical temperature can not effectively be controlled, and operation control is not rigorous, and oil yield and production efficiency are low, and product mixture, the non-alkane material that output is come is more.
The technical solution adopted for the present invention to solve the technical problems is that the waste oil that molecular weight is big adds in the refining equipment, and kerosene, diesel oil, gasoline and residual oil are separated effectively, and its processing step is as follows:
1, waste oil treatment: in waste oil pool, add warm water washing, remove impurity such as earth, gravel, iron filings in the waste oil.
2, distillation: in distiller waste oil is heated to 310-350 ℃, adds nickel vanadium sintered catalyst, waste oil and catalyst ratio are 100:1, waste oil molecule generation open loop, chain rupture, condensation chemical reaction.
3, gasification condensation: carry out in fractionator gasification condensing chamber, have water medium to regulate controlled temperature, bed tempertaure 238-242 ℃ and generate kerosene, 193-197 and ℃ generate diesel oil, 73-77 and ℃ generate gasoline, gasoline direct taps into into storage tank.Major product diesel oil accounts for about 80%, is introduced into the limpid treater of diesel oil, enters the diesel oil storage tank again through after the limpid processing, and residual oil returns in the distiller and refines repeatedly, and a spot of inflammable gas can return and carry out the hydrotreatment utilization.
It is rigorous to adopt positively effect of the present invention to be that mineral waste oil refines the diesel oil technological specification, and the level of automation height is easy to operation, safe and reliable, and oil refining efficient height, cost are low, obtain the base oil product quality and meet national standard.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the invented technology schema.
Embodiment
As shown in the figure, the waste oil that molecular weight is big adds in the special-purpose refining equipment, and kerosene, diesel oil, gasoline and residual oil are separated effectively.Its concrete implementing process step is as follows:
1, waste oil treatment: in waste oil pool, add warm water washing, remove impurity such as earth, gravel, iron filings in the waste oil.
2, distillation: in distiller waste oil is heated to 320 ℃, adds nickel vanadium sintered catalyst, waste oil and catalyst ratio are 100:1, waste oil molecule generation open loop, chain rupture, condensation chemical reaction.
3, gasification condensation: carry out in fractionator gasification condensing chamber, have water medium to regulate controlled temperature, 240 ℃ of bed tempertaures and generate kerosene, 195 ℃ and generate diesel oil, 75 ℃ and generate gasoline, gasoline direct taps into into storage tank.Major product diesel oil accounts for about 80%, is introduced into the limpid treater of diesel oil, enters the diesel oil storage tank again through after the limpid processing, and residual oil returns in the distiller and refines repeatedly, and a spot of inflammable gas can return and carry out the hydrotreatment utilization.
