Description

 Hochfeistungskammermischer for kata / ytische oil suspensions

The present invention relates to a process for the production of diesel oil from hydrocarbon-containing residues in an oil circulation with solids separation and product distillation for the diesel product

The above patent mentions the components of the entry and the delivery in general only. The object of the additional application is to describe these components precisely and to explain them in an exemplary embodiment. These specifications are possible because the high-performance chamber mixer can produce a high degree of underpressure and thus All entry problems on this basis can be solved. An embodiment of the present invention will be described in more detail below with reference to the drawings

1 shows a schematic representation of a system for carrying out the inventive method,

FIG. 2 shows a schematic representation of the system from FIG. 1

The method is first explained with reference to FIG. 1. For the purpose of a blockage-free entry, an emulsion container 2 is arranged on the suction side of a high-performance chamber mixer 1, which has three inlet openings. by an entry system 3, which acts crushing and dosing, adjacent to the entry container 2

The substances to be introduced, dry residue 5, residue sol from the system or as residue 6, lime or soda as neutralizing agent 7 and the catalyst 8 in the mixing funnel 9 enter this entry system 3 through the mixing funnel 9 and the Sammelbehalter 4. Both the Mischtπchter 9 and the Sammelbehalter 4 are equipped with vibrators, which ensure a continuous inflow

The other two openings on the entry vessel 2 are a Kreislaufkatalysatorol- supply 10 from a Olsammelbehalter 15 and a Sammelkatalysatorol supply 11 from an oil collecting container 15, which is arranged at the outlet 29 of this ÖlsammeJbehälters 15. This makes it possible for the catalyst oil to also keep the lime residues in circulation.

On the pressure side of the high-performance chamber mixer 1, a pressure line 12 is attached. It directs the product vapor-oil mixture produced in the high-performance chamber mixer 1 into an evaporator 14. This has a distribution channel 13 which divides the incoming oil-vapor mixture into a plurality of partial streams through perforated plates in an open-ended annular die forming the wall wet and leads to the largest possible surface of the liquid in the evaporator 14.

This ensures that almost the entire product separates in vapor form from the liquid and can settle upwards in a distillation column 18 and, if possible, no product enters the oil collecting tank 15. Repeated splitting of already produced product in the diesel boiling range would reduce the production amount and lower the quality of the product.

The entry system 3 is controlled by a level control container 16, which indicates and regulates the level in the oil reservoir 15, on and off or in the speed regulated. At the lower end of the level control container 16, a pump 17 is arranged, which directs a small amount of oil to the entry system 3 in order to protect it from blockages.

On the steam side of the product, the product vapor is purified in the distillation column 18 by fractional distillation of the entrained oil particles and condensed in the condenser 19. The thereby incurred in the condensation of water are retained in the condenser 19 by a partition wall due to their higher specific gravity on the input side.

From there, the water content passes into a pH measuring container 20 by exchange with the product located there with the water settling down. In the pH measuring container 20 is a pH measuring probe 23 and a conductivity probe 22. Upon reaching the water at the conductivity probe 22, a certain amount of water is discharged into a product water tank 21 and discharged from there into a sewer.

The lighter product diesel or fuel oil passes through the baffle in the condenser on the output side in a product line 24, wherein vaporous product components over a line 26 also as the product in the product line 24 into a product container 25 arrive. A small portion of the product passes via the line 24, regulated via a return valve 28, back into the distillation column 18 in one of the upper floors 27th

The control is set so that the amount controls the return in the column. This produces a different product quality for summer diesel with an average boiling point of 290 ⁰ C, for winter diesel with an average boiling point of 27O ⁰ C and kerosene with an average boiling point of 240 ⁰ C. The cooling of the condenser with circulating water and a recooler 38 with circulation water pump.

Behind the product container is a vacuum pump 37, which keeps the entire system at negative pressure. The sucked gas is added to the generator as intake air or purified in a catalytic exhaust air purification. As gases which are sucked out of the plant fall from the biological substances derived carbon dioxide and possibly resulting from leaks small Gasmengeπ on.

This ensures that no flammable product can escape from the system. The vacuum pump controls the amount of entry and the amount of discharge of non-reactive, inorganic residues that are discharged at the bottom of the system.

The non-reactive components of the input material and the catalyst exchanging with the ions and the added lime or soda-forming salts pass through a control valve 30 and a hot sludge pump 31 into a heat chamber 32.

This is electrically heated to 55O ⁰ C and has on the inside a heat-resistant evaporation vessel with the sludge inlet, a vapor return to the evaporator and a screw discharge 33 for the heated inorganic substances, which reach a Rückεtandsbehälter 34. This is on average 1 to 3% of the input material.

The substances collected in the residue container 34 are subsequently mixed with the water of the container 21. The substances settling in the suspension, metal, glass and ceramic, are separated and the suspension is filtered. The filter residue is again a usable catalyst. The liquid contains the salts formed and is passed into the wastewater.

The containers have relief and pressure equalization lines, such as the feed tank 2, through a venting chamber with check valve 36 with the distillation column - A -
