Abstract
The invention relates to a structured packing special for atmospheric capture of CO2. The invention is characterized in that: the employed structured packing is a corrugated metal plate packing, and the corrugated metal packing plate has thickness of 0.5-1.5mm, a wave crest height h of 12-24mm, an addendum angle beta of 75 degrees and a wave bottom inclination angle alpha of 30-37.5 degrees. The corrugated metal plates are intercrossed and placed together vertical to each other, thus forming the cylindrical structured packing. Bundled and fixed by a metal thin skin, the structured packing has a diameter as a required tower diameter, and the packing is installed in the tower at a height of 200-500mm. The structured packing provided by the invention improves the mass transfer efficiency of a CO2 absorption and capture device, and especially under a low liquid spray density, the efficiency is increased by 10-20%. The use of the new packing can reduce the manufacturing cost of capture equipment, thus lowering the energy consumption and cost of the whole CO2 capture process.
Description
Technical field
The present invention relates to one capture and separation CO from admixture of gas
2absorption tower and the structured packing of desorber inner member used.
Background technology
Global warming has become the fact free from controversy.Greenhouse gases CO
2discharge be the principal element causing climate warming.How from being rich in CO
2atmosphere gas mixture in, comprise the capture and separation CO such as flue gas, refinery gas and hydrogen production exhaust gas
2very important.
According to the pressure height of different application scenarios and unstripped gas, decarbonization method can be divided into dry method and wet method.Dry method comprises absorption method and embrane method, is generally applicable to CO
2the occasion that concentration is higher, pressure is higher; Wet method is solvent absorption, and solvent absorption is used for the occasion of the lower or normal pressure of raw gas pressure.
In structured packing, Chinese patent application (93104269.0) discloses a kind of annular ring wave-shaped filler, and it is characterized in that perforated plate corrugated is arc-shaped, and on described every section of ripple, have one group of ring plate, the ring plate in every two adjacent corrugations is staggered.Chinese patent application (200610053562.8) proposes a kind of plate ripple arranged packing tower, is separated with the plate ripple arranged packing layer of at least one layer of axial diversion between every two-layer oblique template corrugated regular filler layer.Chinese patent application (200810052976.8) proposes screen aperture reticular lamina corrugated filler tablet and structured packing.Chinese patent application (200910099811.0) discloses a kind of plate ripple arranged packing and the manufacture method with plain edge structure.Chinese patent application (200910115360.5) proposes a kind of honeycomb type metal structured packing, and it is made up of at least two layers of mesh pass filler, and every layer of mesh type filler is spaced by metal strap and is formed.Chinese patent application (201010290219.1) discloses a kind of transition curved edge improved plate corrugated regular filler and manufacture method thereof.The Chinese patent application of these structured packing aspects, does not all have special in CO
2the feature of trapping system, designs and proposes suitable structured packing.
For CO
2trapping process is generally the unstripped gas of normal pressure, as flue gas, refinery gas and hydrogen production exhaust gas etc., and the CO containing 5-60%
2, change in concentration scope is large, and pressure is near normal pressure, is generally 0.05-0.15MPa, adopts absorption process to absorb CO
2during gas, liquid-gas ratio is very little, and liquid spraying density is little, even little of 5-10m
3/ m
2h.Metallic plate ripple packing conventional in the market, mainly X-type and Y type, its ripple and horizontal angle (inclination angle) are 45 ° and 60 °, and in low liquid spraying density situation, mass-transfer efficiency is poor.
Summary of the invention
The object of this invention is to provide a kind of normal pressure trapping CO
2special structured packing, especially for the CO in atmosphere gas
2the structured packing of the inner member in the catching apparatus that absorption process trapping technique is commonly used.The structured packing of design, mass-transfer efficiency is high, and resistance is little, and the height of required absorption tower and desorber is little, can save a large amount of equipment investments.
Capture and separation CO in a kind of gas of the present invention
2absorption tower and desorber structured packing used be metal corrugated plate filler, the thickness of this metal corrugated plate filler plate is 0.5-1.5mm, crest height of wave h is 12-24mm, crest apex angle ss is 75 °, and wave base inclination alpha is 30-37.5 °, is put together by mutual for metal corrugated plate intersecting vertical, form the structured packing of a column type, bundled fixing by metal thin skin, structured packing diameter is required tower diameter, and it is 200-500mm that filler is arranged on tower inner height.
This filler is used for the CO under the condition of normal pressure such as flue gas, refinery gas, hydrogen production exhaust gas
2concentration is absorption process trapping or separation of C O in the gas of 5%-60%
2absorption tower in technical process, desorber and water scrubber.Can be used for comprising conventional absorption, the CO of heating desorption
2trapping separating technology; The technique of absorption, vacuum desorption; The technique of absorption, inert gas air lift; Or at trapping or separation of C O
2simultaneously stability be separated SO
2, H
2the technique of S and/or organic sulfur.Be applied to CO
2absorb the technique of trapping, it is characterized in that, described acceptance condition: temperature is 30 DEG C-80 DEG C, pressure is 0.05-0.15MPa; Described desorption condition: temperature is 80 DEG C-130 DEG C, pressure is 0.1-0.2MPa.
The effect of structured packing of the present invention is, improves CO
2absorb the mass-transfer efficiency of catching apparatus, particularly under low liquid spraying density, improve 10-20%.The use of new filler, can reduce the manufacturing cost of catching apparatus, thus reduces whole CO
2the energy consumption of trapping process and cost.
