Definitions
- the present invention relates to a device for the tangential introduction of a gaseous liquid stream into the head of a column in which gas and liquid are separated, the entry into the column head by a conventional radially arranged nozzle, which, however, followed by a special pipe construction , which ensures a smooth as possible, untwisted flow and their tangential exit into the column head.
- gas streams the acid gases such.
- These gas streams may be, for example, natural gas, synthesis gas from heavy oil or heavy residues, refinery gas or in the partial oxidation of organic materials such as coal or petroleum, resulting reaction gas.
- the sour gas content of the gas must be significantly reduced.
- CO 2 needs to be removed from natural gas because a high concentration of CO 2 reduces the calorific value of the gas.
- CO 2 in conjunction with water often entrained in the gas streams, can lead to corrosion on pipes and fittings.
- the chemical solvents have in particular the aqueous solutions of primary, secondary and tertiary aliphatic amines or alkanolamines such as monoethanolamine (MEA), diethanolamine (DEA), monomethylethanolamine (MMEA), diethylethanolamine (DEEA), triethanolamine (TEA), diisopropanolamine (DIPA ) and methyldiethanolamine (MDEA) proved technically, cf. z.
- MMEA monoethanolamine
- DEA monomethylethanolamine
- DEEA diethylethanolamine
- TEA triethanolamine
- DIPA diisopropanolamine
- MDEA methyldiethanolamine
- the treatment of the raw gas with the liquid absorbent is usually carried out in countercurrent process under pressure in an absorption device.
- the latter is usually fed to a desorption device in order to recover the valuable absorbent and to be able to feed it back to the absorption device.
- the gas-laden Absorption liquid relaxes.
- the pressure drop when entering the desorption effected especially in the modern and very powerful absorbents, for example, the tertiary aliphatic alkanolamines such.
- MDEA methyldiethanolamine
- flashed feeds pressurized gas-laden absorption liquid feeds which, upon entry into a regeneration column operating at much lower pressure, immediately release large amounts of gas charge due to the pressure gradient.
- Figure 1 is the schematic representation of a head of a regeneration column with tangential inlet of the prior art
- Figure 2 shows schematically three radial inlet variants of the prior art.
- the head (15) of a regeneration column of the type in question comprises an inlet (17) for the gas-laden absorption liquid.
- This inlet opens into a gallery (18), on which the first great relaxation of the liquid takes place and large quantities of gas are liberated.
- Built-in components (19) are provided above the gallery.
- the released gases leave the column through the outlet (16).
- the feed (17) shown in Figure 1 opens tangentially into the column, which is shown more clearly in the sectional view A-A.
- This tangential inlet ensures a low-turbulence gentle transition into the column and a uniform release of the gas load, so that no rapidly changing and / or asymmetric momentum occur which would permanently lead to damage of the column or the internals due to alternating stress.
- a tangential configuration of the inlet is therefore advantageous to indispensable, especially in flashed feeds.
- FIG. 2 shows in three sectional views a, b and c three embodiments of radial inlets.
- the sectional views a and b represent cross sections through a regeneration column of the type shown in FIG. 1 at the level of the section AA.
- the cylindrical jacket (25, 35) of a regeneration column has a radial inlet (26, 36) which, in the case of the 2a embodiment directly into a voltage applied to the inner wall of the column deflector (27) opens, in which divides the influx and is deflected abruptly by 90 °. In the gallery (28) then distribute the two out of the deflector (27) exiting counter-currents.
- the abrupt deflection of the inflow in the deflector (27) with simultaneous expansion leads to violent turbulence, impacts and shocks, which affect the entire column head and its internals, so that in the long term damage is unavoidable.
- the situation is similar in the embodiment shown in FIG. 2b.
- the through the cylindrical column wall (35) guided radial inlet (36) is connected to a arranged in the axial center of the column T-piece (37) whose ends (39, 39 ') in the space between gallery (38) and column shell ( 35) are angled in the T-plane by 90 °.
- the influx is in this case even deflected by two 90 ° abruptly, causing, as in the case described above, considerable turbulence, shocks and collisions in the top of the column.
- the invention is therefore based on the object, an apparatus for introducing a gas-laden liquid stream in the head of a regeneration column, are separated in the gas and liquid to provide, which is connected to a conventional radial inlet but no sudden 90 ° flow deflections, but as a result, a turbulence-poor tangential introduction of a gas-laden liquid stream in the head of a regeneration column allows.
- a device of the aforementioned type which is characterized by a first pipe bend with a bending angle ⁇ ⁇ 90 °, which is arranged at the inlet of a radial feed line for the gas-laden liquid stream in the column head and connected to the first pipe bend second pipe bend with an angle of curvature of ⁇ 1 ⁇ 90 °, which is curved against the first pipe bend and arranged so that an outlet opening in the vicinity of the inner wall of the column is and the gas-laden liquid flow substantially tangentially to the inner wall of the column can escape into this.
- the length of the straight pipe section is advantageously chosen so that the outlet opening of the second pipe bend is displaced by about 90 ° on the circular arc, which describes the inner circumference of the column, compared to the entry into the column.
- the device according to the invention comprises exactly one outlet opening, which is expediently formed by the tube end of the second tube bend.
- the second pipe bend is followed by another pipe bend (third pipe bend).
- a partial outlet for the gas-laden liquid is provided between the second and third pipe bends. The transition from the second to the third pipe bend is expediently designed so that the partial stream leaving the column exits into the column essentially tangentially to the inner wall of the column and the other partial stream passes from the second into the third pipe bend without a sudden change of direction.
- the bending angles ⁇ and Y of the two pipe bends may be the same or different and be 30 to 60 °, in particular 40 to 50 °;
- each curvature angle ⁇ Y is approximately 45 °.
- the inventive device has the advantage that it can be installed instead of the known radial feeds in conventional regeneration columns of the type in question here, with no costly modifications or changes to the column itself are required.
- the invention therefore also relates to the conversion of a regeneration column with known radial introduction of a gas-laden liquid stream in a regeneration onskolonne with tangential introduction of the liquid flow, wherein the known radial introduction removed and attached to the radial inlet nozzle, the device of the invention described above.
- the device according to the invention is therefore particularly suitable for use in regeneration columns of acid gas scrubber plants. If an aqueous solution of at least one alkanolamine selected from methyldiethanolamine (MDEA), monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), diisopropanolamine (DIPA), amino-di-ethylene glycol (ADG) is used as absorbent for acid gas scrubbing, it is highly recommended to provide the regeneration column with a tangential inlet according to the invention.
- MDEA methyldiethanolamine
- MEA monoethanolamine
- DEA diethanolamine
- TEA triethanolamine
- DIPA diisopropanolamine
- ADG amino-di-ethylene glycol
- the release of the gas load is therefore only fairly trouble-free, if a low-turbulence smooth, tangential introduction of the gas-laden liquid flow takes place in the regeneration column.
- the device according to the invention is particularly suitable for this purpose. It is advantageous to choose the total alkanolamine concentration of the aqueous absorption solution in the range of 38 to 50 weight percent. In addition, it is advantageous to add the aqueous absorption solution, piperazine, methylpiperazine and / or 3-methylamino-1-propylamine (MAPA) as activator. When using MDEA as an absorbent, the concomitant use of said activators is particularly advantageous.
- FIG. 3 shows an embodiment of the invention with an outlet opening.
- Figure 3 shows schematically the cross-section of a regeneration column at the level of introduction of the gas-laden liquid stream.
- the designated 1 coat of the head of a regeneration column is provided with a radial feed line 3, which passes immediately after entry into the column in a first pipe bend 2.
- a flange can be provided with which the inventive
- Pipe bend construction is attached to the supply line 3.
- the pipe bend 2 shown in Figure 3 has a bending angle ⁇ of 45 ° and is connected to a straight pipe section 7, which merges into a second, opposite curved pipe bend 4.
- This second pipe bend also has a curvature angle (Y) of 45 °.
- the length of the straight pipe section 7 is selected in the case shown in FIG. 3 such that the second pipe bend is offset from the inlet connection 3 by approximately 90 ° on the circular arc described by the inner circumference of the column.
- Its outlet opening 5 is located very close to the column inner wall 6, so that upon introduction of the gas-laden liquid flow, it strikes the inner wall 6 of the column 1 in an almost tangential manner, where the latter has a reinforcement 8.
- the incoming liquid flow is distributed in and on a conventional gallery 9 in the column head.
- the pipe construction according to the invention which converts a radial inlet into a tangential inlet, has the shape of a lying elongated question mark or a stretched S.
