The invention is based on a complex process »For the production of synthetic bitumen on asphaltenes and oil

The formation of synthetic bitumen by mixing asphaltenes with oil is known. In a known method of production of such a bitumen, asphaltenes are separated from a mineral oil liquid by adding an additive and centrifuging the resulting suspension in succession switched centrifuges «« «if an additional amount of pelletizing agent is suggested before centrifuging.

by. Applying a falling agent and separating the precipitated asphaltenes, whereupon the concentrated asphaltenes a residual oil can be added and oil from the obtained The mixture is removed by distillation and the synthetic bitumen is obtained as a bottom product

The ash-free and asphaltene-free oil is partially used the separation of the asphaltenes from the residual oil (at what stage it still contains precipitant) «through Distillation can be removed and partly during the distillation of the mixture of asphaltenes and residual oils

Sin particularly interesting point in the process according to the! Invention is its great adaptability, which allows the production of bitumen from any hardness "of the like for road construction. Is needed, without being dependent on the selected tu Ausgangematerial * This is achieved by That the mixing ratio of asphaltenes and residual oil as well as the distillation of the mixture can be changed depending on the requirements. Another part of the gate "which results from the combination of the production of asphaltenes and the manufacture of bitumen" consists in receiving the asphaltenes in the form of a suspension which can be easily mixed with the Ztüekstandsöl. Without such a subdivision, the asphalts would "necessarily have to be produced free of volatile precipitants. This is interesting for the production of synthetic bitumen" because dissolving such semi-solid asphaltenes in residual oil is a problem in itself "3 in another part of the process in that W mixing the suspension of asphalt

Suitable residual oils from which the asphaltenes can be obtained and suitable residual oils which the asphaltenes obtained are added «are residual mineral oil fractions, which have been produced by direct distillation of crude oils, which contain asphaltenes and residues contain, caused by thermal or catalytic gap » processes have been obtained · When a crude has a low It can contain volatile components as a starting material for the process, as it is »used» i.e. after removal by distilling only the flüefc » tigeten components · Preferably, fractions with a Initial boiling point of at least 300 ° used »

Suitable lällungsmlttel for the extraction of the Aspaaltene and the ash-forming constituents are liquids in which asphaltenes - if at all - sohow dissolve. Examples are aliphatic hydrocarbons old straight or branched chain, such as pentane, hexane, heptane and isooetane, Oylische aliphatic hydrocarbons, such as methylcyclohexane and dimethylcyolopentane, and polar liquids such as diethyl ether and Ethylacet · iowlo Gemieohe of liquids.

The overflow opening and the lower drain opening are related to one another as 1.5 «3i1 to 2.5» 3 »2, and 75 to 95% of the supplied oil is discharged from the hydrocyclone via the overflow opening Durohmeeeer in the cylindrical part is 10 mm and the diameter of the inlet opening, overflow opening and lower drain opening is 2 mm, 3 mm or 1.5 µl. At an inlet pressure of 5 * t, the throughput of this hydrocyclone is 150 liters of asphalt suspension / hour Results were also obtained with a hydrocyclone, the diameter of which in the cylindrical part was 25 * a and the diameter of the ileal inflow opening, overflow opening must «fteV lower drainage opening 5» · »7 * 5« ab * w. 3.75 «m · The throughput was 1 w / h at an inlet pressure of 2.5 at, and with a hydrocyclone whose diameter in the cylindrical part was 100 mm and the diameter of the inlet opening, overflow opening and lower drain opening 20 mm, 30 mm or 15 mm, the Durohsats with a valley imprint of 10 at 30 a * / h

In order to increase the capacity in terms of throughput, several hydrocyclones can be kept in parallel, which in a very convenient form through the use of multi-cyclones can be achieved, which are understood to be structural units that contain a large number of hydrocyclone « and in the beginning with a supply line and two discharge lines are relieved

Bel use of hydrocyclones connected in series are, let ee desired, purposes of obtaining an asphaltene suspension with a low oil content, the asphalt suspension emerging from the lower drain of the first hydrocyclone or multi-cyclone to be diluted with precipitants before it is fed into the second hydrocyclone or multicyclone · 3s then a sufficient amount of precipitant is exposed to the Oil content of the liquid phase of the asphaltene suspension to 2.5 VoI .- ^ or less to set
