Definitions
- the invention relates to a device for carrying out a gas scrubbing, in which gas from bottom to top and detergent from top to bottom by a
- Washing column are performed, with at least two laundry sections in the
- Washing column are arranged one above the other, of which the upper is bounded below by a chimney tray, from which at least a part of the detergent loaded in the upper washing section deductible at a provided in the chimney flue outlet and as detergent at an opening provided in the lower washing section discharge point in the lower washing section can be introduced, wherein in the flow direction behind the take-off point and before the
- the washed-out carbon dioxide can be compressed and, if necessary, pressed into the ground after further treatment or put to another use. In this way, for example, a nearly carbon dioxide emission-free operation of coal power plants is possible.
- a flue gas C0 2 scrubbing is carried out in a scrubbing column in which at least two washing sections are arranged one above the other and are separated from each other by a chimney tray, wherein in the lower section of the first and in the upper section of the second washing step take place.
- a washing column has in its lower part via a device for supplying the flue gas to be washed and at its head via a device for the withdrawal of the washed flue gas.
- it has facilities for supplying unladen detergent at the top of the column, for the withdrawal of loaded detergent from the chimney tray, for the supply of laden W schstoff in the lower washing section and for the withdrawal of the bottom product from the sump space.
- the loaded detergent which collects in the chimney tray, is withdrawn from this and at least partially promoted by means of a pump to a heat exchange device in which it is cooled to increase the solubility coefficient.
- Heat exchange device with the detergent guaranteed by a pump.
- a pump drive, a pump control and a liquid template within the wash column are necessary, which is significant
- Object of the present invention is therefore to provide a device of
- the object is achieved by the device according to the invention in that the withdrawal point is arranged so far above the point of introduction that the hydrostatic energy is sufficient only to flow through the heat exchange device and for introducing the detergent into the lower washing section.
- the invention is based on the idea to replace the pump energy by hydrostatic energy.
- a height difference is set between the take-off point and the point of introduction of the detergent, which is a hydrostatic pressure of the detergent has the consequence, for a flow through the
- Heat exchanger device and sufficient for the introduction of the detergent in the lower washing section.
- the driving force for the detergent is therefore no longer generated by the pump, but solely by the hydrostatic energy due to the difference in height between the discharge and discharge point.
- a pump is used in order to be free in the installation of the heat exchange device and on the other hand a higher
- the heat exchange device is outside the wash column. arranged and connected via lines on the one hand to the withdrawal point and on the other hand to the discharge point. In this case, the withdrawal point is arranged at a height above the point of introduction, from which a hydrostatic energy of the
- Heat exchange device can be overcome.
- the chimney tray in the wash column is designed so that at the trigger point of the lower
- Washing section of certain detergent can form a static fluid pressure, which is sufficient to compensate for the pressure losses experienced by the detergent on its way from the chimney tray in the lower washing section. Because of the frictional losses in the ducts and the pressure losses caused by the heat exchanger, heights of several meters may result for the chimney tray. Preferably, the height difference between the take-off point and the point of introduction is about 2 to about 8 m.
- An advantageous embodiment of the invention provides that at least three, separated by fireplace floors washing sections are arranged in the washing column, wherein the withdrawal point for the detergent in the area of the lowest
- Chimney tray and the introduction point for the detergent are arranged in the region of the lowest washing section and the heat exchange device between
- Embodiment can be used for example with advantage for amine scrubbing of flue gases.
- these washing sections may optionally be additionally provided a pre-wash.
- the invention is suitable for all gas scrubbing in which the loaded detergent withdrawn from an upper washing section and after a
- Heat exchange to be initiated in a heat exchange device in a lower washing section is provided.
- the invention is provided for physical gas scrubbing in which the withdrawn detergent is cooled in the heat exchange device to increase the solubility coefficient and introduced into the lower washing section.
- the invention further relates to a method for carrying out a gas scrubbing in which gas from bottom to top and detergent from top to bottom are passed through the scrubbing column, wherein at least two washing sections in the
- Washing column are arranged one above the other, of which the upper is bounded below by a chimney tray, from which at least a portion of the loaded in the upper washing section detergent withdrawn via a
- Heat exchange device passed and introduced as a detergent in the lower washing section.
- the object is achieved in that the detergent is driven solely due to the hydrostatic energy through the heat exchanger to the lower washing section.
- Detergent at least a portion of the carbon dioxide is washed out.
- FIG. 2 shows a washing column with a gravity-driven intermediate cooler
- FIG. 3 shows a washing column with an elevated level
- FIG. 1 shows a washing column for flue gas C0 2 scrubbing according to the prior art, in which carbon dioxide-containing flue gas obtained, for example, in a coal-fired power plant, the carbon dioxide is largely removed by means of an amine-containing detergent in several washing sections.
- the leached carbon dioxide can be pressed in the background after appropriate, not shown in the figure, treatment or another use, eg as a feedstock for bioreactors (algae cultures) for fuel production, fed.
- the flue gas to be purified is introduced into the wash column T and then flows upward through the lower washing section WS1.
- Detergent which has already been used in the upper washing section WS2 for gas scrubbing, is collected in the chimney tray K, which closes the washing section WS2 down, and passed via lines 5 and 4 in the lower washing section WS1.
- the detergent flows in the lower washing section WS1 from top to bottom, and washes on its way out of the counter-current flue gas part of the
- Carbon dioxide before it - now loaded with C0 2 and possibly other components - in the sump space S of the wash column T is collected. That already partially cleaned flue gas flows through the chimney tray K up to the top
- Washing section WS2 in which it is further purified from carbon dioxide by countercurrent detergent regenerated at the head of the washing section WS2 via line 2. Via line 3, the purified flue gas is finally withdrawn from the wash column T.
- the scrubbing agent withdrawn from the scrubbing column via line 5 is cooled by heat exchange with a refrigerant in a heat exchanger 6, which is provided as a heat exchange device and is usually referred to as an intercooler.
- the cooled detergent is introduced via line 4 into the lower washing section WS1.
- the flow through the heat exchanger 6 is ensured by a pump 7.
- Heat exchanger 6 is not guaranteed by a pump, but solely by the hydrostatic pressure of the withdrawn via line 5 from the fireplace floor K detergent.
- the withdrawal point A is disposed at a height above the discharge point E, which has a sufficient for overcoming the pressure loss in the lines 4 and 5 and in the heat exchanger 6 hydrostatic pressure result.
- the height difference between the withdrawal point A and the point of introduction E is in practice e.g. 2 to 8 m.
- FIG. 3 shows a variant of the exemplary embodiment shown in FIG. 2, in which the heat exchanger 6 is arranged at an elevated level in order to prevent the heat exchanger
