Definitions
- the invention relates to a process for the continuous treatment of soot water, which results from a partial oxidation of heavy metal-containing liquid hydrocarbons.
- soot In a high-temperature process such as a partial oxidation of heavy metal-containing liquid hydrocarbons falls very finely divided soot, which is mainly discharged by washing the soot-containing raw gas with water from the process. Up to about 2% carbon black contains the soot water.
- the soot contains heavy metals, especially nickel and vanadium.
- the soot water after washing has a temperature between 150 0 C and 300 ° C at a pressure of 40 to 85 bar. It is generally sent through a pressure-expansion device and a cooling device to the soot water in the atmospheric state and acceptable temperature to obtain, so that a further treatment of the soot water is possible.
- the soot water has a high proportion of water, it has a high-viscosity consistency, and the soot hardly settles.
- the soot water can only be dewatered with great effort.
- the soot water is usually collected in tanks and later subjected to filtration. This is a discontinuous process, the water separated by the filtration being heated up as working water, returned to the process, and the leftover residue is deposited in containers for further processing.
- DE 40 03 242 A1 discloses, the soot water is mixed in a sewage sludge treatment plant with a sewage sludge, drainage aids such as organic flocculant is added, then the soot water is subjected to filtration. This requires large amounts of drainage aids and large space requirements, which economically means a great burden.
- DD 10 63 35 also describes a process for the treatment of soot water, wherein a lime-containing suspension is added and a sedimentation is effected.
- soot water is subjected to a chemical process, wherein the contaminated wastewater can not be recycled without further treatment.
- the disclosure DE 4331322 A1 is directed to a method for the separation of undesirable substances from a sludge in a sludge purification plant with settling tanks and agitators.
- the removal of soot and heavy metals is mentioned after a flue gas desulfurization plant, to a hydrocyclone is used for thickening. Because of the tough pasty nature of the soot water from a partial oxidation of liquid hydrocarbons, the use of a hydrocyclone for dewatering is not favorable.
- the soot water can also be filtered off discontinuously. This requires large-volume stacking tanks before and after filtration, but this leads to more costs compared to the continuous process.
- the invention is therefore based on the problem to develop a method for the continuous treatment of soot water from a partial oxidation of heavy metal-containing liquid hydrocarbons, which is technically simpler and more economical compared to the prior art.
- the invention solves the problem by a method for the continuous treatment of soot water obtained in a partial oxidation of heavy metal-containing liquid hydrocarbons, wherein the soot water at a temperature of 15O 0 C to 300 0 C and a pressure of 40 to 85 bar is withdrawn from the gasification process, a pressure relief device passes to reduce the pressure up to about 5 bar, and then without the addition of adjuvants as a Vorentskysstechnikshack at a pressure of up to 5 bar and a temperature of up to 150 0 C is centrifuged to a solids content of up to 10%, a pasty, heavy-metal-rich carbon black slurry being obtained and a low-metal-content centrate being obtained, which is at least partially recycled as useful water back into the gasification process.
- the soot water from a partial oxidation of heavy metal-containing liquid hydrocarbons has a temperature of 150 ° C to 300 0 C and a pressure of 40 to 85 bar. It must first go through a pressure-release device to the pressure of up to about 5 bar to relax. The soot water is cooled by a cooling device to 150 0 C, if the temperature of the soot water is above 150 ° C. The drainage of the soot water is carried out in two stages.
- the soot water is passed through a centrifuge at a pressure of up to 5 bar and a temperature of up to 150 ° C without the addition of auxiliaries, whereby a thick, heavy metal-rich soot sludge and a heavy metal-poor centrate are obtained.
- the carbon black slurry contains up to 10% solids.
- the centrate which has not been contaminated by any additives, is largely returned to the gasification process as used water. Before the recirculated useful water flows back into the gasification process, it is heated up to 150 0 C, if the temperature of the centrate is below 150 0 C. Due to the low loss of the temperature of the centrate during operation, the centrate also needs to be slightly heated again.
- the pre-dewatering is carried out with the aid of a sedimentation centrifuge.
- a sedimentation centrifuge This is a Vollmantel- screw centrifuge or a disc centrifuge, because these centrifuges can in a Pressure of up to 5 bar and a temperature of up to 150 0 C perform the drainage of soot water.
- the heavy metal-rich soot slurry is subjected to a post-dewatering up to 20% solids content.
- a post-dewatering up to 20% solids content.
- the post-dewatering can also be carried out in a drying plant or spray drying.
- the soot slurry can be further dewatered in a deck oven and then burned.
- the invention will be explained with reference to the drawing Fig. 1.
- the resulting soot water from the scrubber (1) is first in a pressure-release device (2) the pressure of 40 - 85 bar relaxed to about 5 bar. If the temperature of the soot water above 150 0 C, the soot water is cooled in an air or water cooler (3) to about 15O 0 C.
- the soot water is pre-dewatered at a pressure of up to 5 bar and a temperature of up to 150 0 C by a centrifuge (4), wherein a pasty, heavy metal-rich Rußschlamm (6) is obtained and a heavy metal poor Zentrat (5) is obtained , which is returned as useful water back into the gasification process (10), this, the useful water is heated to 150 0 C, if the temperature of the centrate is below 150 0 C.
- the carbon black slurry (6) is further dewatered in a post-dewatering (7) up to 20% solids content.
- the post-dewatering (7) can also be carried out optionally with filter aids.
- the resulting water (8) is passed on for treatment.
- the filter cake (9) with about 20% solids content is puncture resistant and landfillable and is available for further processing.
- the process of the invention is characterized in that the pre-dewatering is purely mechanically without the addition of excipients in a centrifuge at a pressure of up to 5 bar and a temperature of up to 15O 0 C feasible, the accumulating centrate as the only water slightly heated and returned to the gasification process. This eliminates the cost of the additional auxiliaries and energy, the use of water in the process is greatly reduced, eliminating the tanks for collecting the soot, which is a great economic advantage over the prior art.
- the pre- and post-drainage can be carried out by means of simple drainage equipment. ] List of reference numerals
