Description

The present invention relates to a method for producing Diesel oil from hydrocarbon containing residual substances in an oil cycle with solid deposition and product distillation for the Diesel product.

In the previously mentioned patent specification, the components of the input and output are dealt with only in general manner. The goal of the supplementary application is to precisely describe these components and to explain them in an embodiment. These precisions become possible since the high-performance chamber mixer is able to produce a high negative pressure, and thus all of the input problems can be solved based thereon. An embodiment of the present invention is described in more detail below by way of the drawings. There show:

FIG. 1 a schematic representation of a plant for performing the method according to the invention;

FIG. 2 a schematic representation of the plant of FIG. 1.

By way of FIG. 1, first, the method is explained. For the purpose of a clogging-free input, on the suction side of a high-performance chamber mixer 1, an input container 2 having three input openings is disposed. At the upper end of the input container 2 there is the first input opening, the residual substance input 4, which adjoins the input container 2 through an input system 3 acting in crushing and metering manner.

The substances to be input, residual substance dry 5, residual oil from the plant or as a residual substance 6, lime or soda as a neutralising agent 7 and the catalyst 8 in the mixing hopper 9, enter this input system 3 through the hopper 9 and the collecting container 4. Both the hopper 9 and the collecting container 4 are equipped with vibrators ensuring continuous inflow.

The other two openings at the input container 2 are a cycle catalyst oil supply 10 from an oil collection container 15 and a collection catalyst oil supply 11 from an oil collection container 15 disposed at the discharge of this oil collection container 15. Thereby, it is made possible that the catalyst oil also retains the lime residues in the cycle.

On the pressure side of the high-performance chamber mixer 1, a pressure line 12 is attached. It passes the product vapour-oil mixture produced in the high-performance chamber mixer 1 into an evaporator 14. It has a distribution gutter 13 dividing the entering oil-vapour mixture into a plurality of partial jets through perforated sheets in an annular nozzle with open end, which wet the wall, and which results in a surface of the liquid in the evaporator 14 as large as possible.

Thereby, it is achieved that almost the entire product separates in vaporous state from the liquid and is able to deposit upwards in a distillation column 18, and no product will enter the oil collection container 15, if possible. Repeated cleavage of already generated product in the Diesel boiling region would reduce the production amount and decrease the product in quality.

The input system 3 is turned on and off and speed controlled by a level controlling container 16 indicating and controlling the level in the oil collection container 15, respectively. At the lower end of the level controlling container 16, a pump 17 is disposed, which passes a small amount of oil to the input system 3 in order to protect it from obstructions.

On the vapour side of the product, the product vapour is purified from the entrained oil particles by fractioned distillation in the distillation column 18 and condensed in the condenser 19. The water portions arising in the condensation are retained in the condenser 19 by a partition on the input side due to their higher specific gravity.

From there, the water portion enters a pH measuring container 20 by exchange with the product located there with the water settling downwards. In the pH measuring container 20, there 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 container 21 and from there discharged into an overflow pipe.

The lighter product, Diesel or fuel oil, enters a product line 24 on the output side through the separating sheet in the condenser, wherein vaporous product portions enter a product container 25 through a line 26 like the product in the product line 24. A small portion of the product gets back in controlled manner into the distillation column into one of the upper bases 27 through the line 25.

Therein, the control is adjusted such that the amount controls the return in the column. It generates a different product quality for summer Diesel with an average boiling temperature of 290° C., for winter Diesel with an average boiling temperature of 270° C., and for kerosene with an average boiling temperature of 240° C. Cooling the condenser is effected with cycle water and a heat exchanger 38 with cycle water pump.

Behind the product container, there is a vacuum pump 37 which keeps the entire system under negative pressure. The sucked gas is added in the current generator as intake air or purified in a catalytic exhaust air purification. As gases sucked off from the plant, the carbon dioxides derived from the biologic substances and the small gas amounts possibly derived from leaks result.

Thereby, it is ensured that no combustible product can exit the plant. To this end, the vacuum pump controls the amount of input and the amount of output of the non-reactive, inorganic residues discharged at the lower end of the plant.

The non-reactive portions of the input substance and the salts forming by the ion-exchanging catalyst and the added lime or soda enter a heat chamber 32 through a control valve 30 and a hot sludge pump 31.

It is electrically heated to 550° C. and has a heat-resistant evaporation container with the sludge entry on the inner side, a vapour return line to the evaporator and a screw output 33 for the heated inorganic substances entering a residual container 34. On average, it is 1 to 3% of the input substance.

The substances collected in the residual container 34 are subsequently mixed with the water of the container 21. The substances depositing in the suspension, metal, glass and ceramics, are separated and the suspension is filtered. The filter residue is re-utilisable catalyst. The liquid contains the formed salts and is passed into the waste water.

The containers have relieve and pressure balance lines like the input container 2 connected to the distillation column through a vent chamber with check valve 35. Furthermore, all of the heat carrying parts are doubly isolated with an alumina fibre mat on the surface and an isolating mat thereon. On the outside, a cover sheet is disposed, which is formed as a closed chamber on the turbine, which can withstand a small overpressure.

In one embodiment, the method is explained. A high-performance chamber mixer 1 with an electrical power of 200 kW sucks the solids from a collection container 2 having a volume of 800 l from the Correau pump of the Correau Paris, a crushing and metering gear pump of 37 kW. The container located above has a capacity of 2 m3. The connecting line is DN50.

The connecting lines between the collection container 2 and the oil collection container 15 are relatively small to allow a high mixing action in the collection container with high oil exit speed and controlled negative pressure. They have a diameter of 1.5 inch and valves controlling the negative pressure in the collection container 2 depending on the material located at the input 3. The relieve line with check valve 36 has a diameter of ¾ inch.

The evaporation container 14 has a capacity of 2 m3 and a distribution gutter 13 with a width of 80 mm and three rows of holes with a hole diameter of 8 mm, wherein the inner and outer row of holes have inclined bores from the centre towards the wall and the interior space. The oil collection container 15 disposed below has a volume of 1.5 m3 and the level container has a volume of 100 litres.

The distillation column 18 has 15 bubble trays with each 52 bubble caps having a diameter of 600 mm. The condenser 19 has a volume of 300 litres. The output system has the control valve 30 DN50 with a hot sludge pump without plastic parts, and is connected to the heat chamber 32, a heating furnace of the company Nabertherm with 15 kW power, and a vapour pipe 35 to the evaporator 14 with a diameter of 1.5 inch, isolated and provided with condensation loops.

The residual output 33 is a screw having a diameter of 200 mm and a closure envelope over the connection from the residual container 34 with a volume of 1 m3. The line to the pH container 20 has a diameter of 1.5 inch and the pH container has a volume of 0.5 m3 with conductivity sensor 22 and pH gauge 23. The water collection container 21 has a volume of 1 m3.

The device for performing the method is explained by way of FIG. 2. On the suction side of the high-performance chamber mixer 101, an input container 102 is disposed, which has input openings. At the upper end of the container, there is the first input opening, the residual substance input 104 adjoining the input container 102 through an input system 103 having gears and a metering insert.

The input openings, residual substance dry 105, residual oil from the plant or as a residual substance 106, lime or soda as neutralising agent 107 and a catalyst 108 in the mixing hopper 109 are connected to the input system 103 through a hopper 109 and a collection container 104. Both the hopper 109 and the collection container 104 are equipped with vibrators.

The other two openings at the input container 102 are the cycle catalyst oil supply 110 from an oil collection container 115 and the collection catalyst oil supplies 111 from an oil collection container 115 disposed at the discharge of this oil collection container.

On the side of the condenser opposing the input side, lines 124 and 126 are attached at the bottom and at the top, which are connected to a Diesel product container 125. An adjusting valve 128 is disposed in the line 124, which is connected to a connecting line to the distillation column. The adjusting valve is communicated with an electronic control, which is set to a temperature measurement. This control has the indications Summer Diesel, Winter Diesel and kerosene.

On the cooling side, the condenser 19 is connected to a heat exchanger 138 with cycle water pump. After the product container, there is a vacuum pump 137, which is thereby connected to all of the parts of the plant.

At the lower end of the oil collection container 115, the residual output valve 130 is disposed. It is connected to a hot sludge pump 131 and a heat chamber 132. It is located in an electrically heated furnace and has a vapour output 135 besides the input from the hot sludge pump 131.

This line is also isolated and has condensate loops with drain cocks and terminates in the evaporator container 114. The heat chamber 132 has a discharge screw 133 on the output side, which is connected to an ash container 134.

A suspension chamber follows the residual container 134, which has a connecting line to the water container 121 and has two outputs. The one output at the upper side is connected to a filter press suitable for catalyst sludge, and the lower side is connected to a reusable material container for ceramics, metal and glass.

The containers have relieve and pressure balance lines as the input container 102 connected to the distillation column through a venting chamber with check valve 135. Furthermore, all of the heat carrying parts are doubly isolated with an alumina fibre mat on the surface and an isolating mat thereon. On the outside, a cover sheet is disposed, which is formed as a closed chamber on the turbine, which can withstand a small overpressure.
