Definitions
- the invention relates to a method for dissolving a quantity of gas in a flowing quantity of liquid according to the preamble of claim 1 and an arrangement for carrying out the method.
- a method of the type identified in the introduction and an arrangement for carrying out the method are, for example, from the company publication "Haffmans C02 measuring and control system", type AGM-05, from Haffmans BV, RD Venlo, Netherlands, pages 2 to 5, known.
- CO 2 gas and beer are brought together in a so-called carbonating device.
- a C02 line ends in the middle of a beer line, and the distribution of the C02 gas takes place via static mixing elements.
- further static mixing elements ensure that the bubble distribution is maintained, which is a necessary prerequisite for the desired mass transfer (absorption of gas into liquid).
- the process engineering and fluid mechanics requirements for the gas / liquid mass transfer are well known.
- the gas must be supplied to the liquid, dispersed in it and distributed homogeneously over the cross section through which the liquid flows.
- the so-called equilibrium curve the solution equilibrium between gas and liquid, provides the maximum amount of gas which is soluble in the liquid at a given line pressure and a given temperature.
- the amount of gas resulting from the solution equilibrium can, if it is offered to the liquid in exactly this amount, theoretically, they can only be dissolved in the liquid over an infinitely long period of time. In practice, therefore, the solution equilibrium is generally dispensed with and the choice of the changeable operating parameters ensures that there is a sufficient concentration gradient between the equilibrium concentration (also saturation concentration) and the desired and finally occurring Actual concentration is given.
- Loop reactors are to be understood as apparatuses in which at least one circulation, defined and directed to encompass the total flow, takes place in a fluid or fluidized system. In this case, a continuous flow can be superimposed on the circulating flow, as a result of which the flow pattern of a "loop" is created. There are loop reactors with internal circulation and those with external circulation.
- a loop reactor is particularly useful when used in the food and beverage industry, where it is extremely important that all areas of the reactor are cleaned in a biologically flawless manner not a particularly cleaning-friendly or ClP-compliant arrangement (CIP: abbreviation for "cleaning in place", which means “can be cleaned on the spot in the flow”), and on the other hand it may have to be classified as a pressure vessel, which determines certain requirements - has to meet safety requirements, which means that it can be subject to approval or monitoring, which makes it technically complex and expensive from the outset.
- CIP cleaning-friendly or ClP-compliant arrangement
- DE 39 20 472 A1 discloses a method for the defined loading of a liquid with a gas, in which the loading process at a specific point in the flow path of the liquid is essentially ended by coalescence of the undissolved gas bubbles. Unresolved, coalesced gas bubbles are either redispersed and mixed in the liquid in the course of the flow path of the liquid to be loaded, or they are separated from the liquid.
- the known device for carrying out the above-mentioned method provides for this at the end of the loading section a separating device in which a separation of undissolved gas bubbles from the liquid is achieved by centrifugal forces in the rotating liquid.
- This separating device is a container in which the rotating liquid forms a rotational paraboloid, over whose free surface the undissolved gas bubbles are separated (column 4, lines 37 to 51). Because of these conditions, the separated material flow is a pure gas flow, and no further statements are made regarding its further use.
- the object of the present invention is to increase the amount of gas which is actually soluble in a liquid under given conditions compared to known processes.
- the arrangement for carrying out the method should be simple in terms of structure, cleanable in flow (ClP-capable), and its adaptation to certain practical requirements and its regulation should be as simple as possible.
- the separation of the total flow into a bubble-free liquid flow and a gas / liquid flow formed as a two-phase flow ensures, on the one hand, that no uncontrollable after-gassing takes place in the liquid continued from the separation point.
- the separation is the prerequisite for the return of a partial flow.
- the recirculated gas / liquid flow superimposes itself as a circulating flow on the supplied inaccurate or fumigated liquid flow, which forms the continuous flow.
- the recycling offers the possibility of redispersing the undissolved gas bubbles contained in the circulating stream and distributing them homogeneously in the overall stream.
- the concentration gradient is increased at the point where the flow through and the circulation flow are brought together, and the superimposition of both flows also results in increased turbulence there.
- the gas in the recirculating gas / liquid stream is at least partially redispersed in its carrier liquid before being combined with the supplied non-degassed or fumigated liquid stream (continuous flow).
- This measure contributes to a further improvement in the mass transfer.
- another embodiment of the proposed method according to the invention provides that the combined gas / liquid mixture is subjected to flow guidance on curved paths and the necessary for this Rotational energy is denied from the energy of the flowing gas / liquid mixture, which results in a relatively simple implementation of this process step.
- the arrangement for carrying out the method can be designed in the form of simple pipelines in the area of the flow, the total as well as the circulation flow, there are extremely easy-to-clean and therefore ClP-compliant flow and system areas which do not contain any pressure vessels in the Contained sense of the relevant regulations.
- the gas in the returning gas / liquid flow in the sense of the previously proposed process engineering measures, can be fed with the supplied un-gassed or fumigated partial liquid flow before being fed into the system - In a carrier liquid, it is particularly simple and effective to redisperse it and distribute it homogeneously over the return line cross section, which serves to further improve the mass transfer.
- the proposed arrangement can be regulated in a very simple manner by the second conveying device, so that it can be easily adapted to changing operating conditions.
- the gas flow By introducing the gas flow into the return line behind the second conveying device, its properties which have a favorable influence on the redispersion of the gas bubbles are also made usable for the freshly supplied gas flow.
- the outlay in terms of apparatus is reduced compared to one Design of the arrangement in which the gas flow is introduced directly into the pipeline.
- the separating device as a centrifugal separator, specifically in a first embodiment as a hydrocyclone, as is provided for in another embodiment of the proposed arrangement, the entire flow is separated into a bubble-free continuous flow and a two-phase flow (gas / liquid flow) Circulation current possible in a particularly simple, but nevertheless extremely effective manner.
- the return line is connected to the dip tube of the hydrocyclone.
- the separating device When the separating device is designed as a hydrocyclone, under certain operating conditions, so-called "drum formation” can occur, as a result of which gas which concentrates in the vortex core is partially entrained in the drain arranged coaxially in the separating device. Special constructive precautions are then required in the drain so that the gas, at least up to a certain degree of loading of the liquid with gas, is retained in the separating device and is discharged solely via the immersion tube used to discharge the two-phase flow (gas / liquid flow) can be.
- the separation line even under the conditions of extremely high gas-laden liquids, improves compared to the formation of the separation device as hydrocyclic ion, if, as is provided by a further advantageous arrangement according to the invention, it is designed as a container in which the inlet enters tangentially and the outlet opens tangentially in continuation of the flow direction, and a dip tube engages a bit in the interior of the container via its boundary surface on the discharge side in the direction of the axis and concentrically to the lateral surface of the container, the dip tube engaging on the other hand is connected to the return line.
- the outlet like the inlet, is also arranged in the jacket area of the container, which preferably allows the degassed liquid rotating in this area to be removed.
- the liquid rotating in the center, in the region of the container axis, and highly loaded with gas now only has the possibility of leaving the separating device in the form of the two-phase flow (gas / liquid flow) via the immersion tube. It is essential that the immersion tube is arranged in the outlet-side area of the separating device so that the residence time necessary for separating the gas bubbles from the jacket area into the axial area of the container is available for the gas / liquid mixture flowing through the container.
- the second delivery device as a self-priming centrifugal pump , preferably as a side channel pump.
- Self-priming centrifugal pumps are relatively simple in construction; They can convey both a two-phase mixture and pure gas, they are self-cleaning, they have no abrasion and therefore require little maintenance.
- FIG. 1 shows a schematic representation of a first exemplary embodiment of the arrangement for carrying out the method according to the invention with a separating device designed as a hydrocyclone;
- FIG. 2 shows a second exemplary embodiment of the arrangement for carrying out the method according to the invention, the separating device being designed according to a particularly advantageous embodiment according to the invention, and
- FIG. 2a shows a plan view of the separating device according to FIG. 2 with the connections for the inlet, outlet and immersion pipe.
- the arrangement (FIG. 1) consists of a pipeline 1, which consists of the pipeline sections 1a and 1b.
- the pipeline section la opens into a static mixing device 5, which is optionally followed by a solution section 5a.
- the entire mixing and solution device can also consist of only one solution section 5a.
- the static mixing device 5 can be constructed from a single static mixer or a mixing element or a plurality of static mixer connected in series; it is referred to below as "static mixer 5".
- the static mixer 5 or the solution section 5a are connected to an inlet 6a of a separation device 6, in which, according to the invention, the gas / liquid mixture is separated into a gas / liquid and a bubble-free liquid flow.
- the pipeline 1 is continued behind the separating device 6 in the pipeline section 1b via an outlet 6b arranged in the foot region thereof.
- a return line 7 is located at the head region of the separating device 6 connected, which engages in the interior of the separating device 6 via an immersion tube 6c and which, on the other hand, opens into the pipeline section 1a at a second introduction point 9.
- a gas line 3 serving the gas supply G which is led via a metering device 10, leads via an introduction point 4 into the return line 7 behind a second conveying device 8 arranged therein.
- the introduction point 4 as is provided by further embodiments of the arrangement according to the invention, can also be arranged in front of or behind or at the second introduction point 9 (dash-dotted representation of the point at the Introductory point 4 merging parts of the gas line 3).
- a separating device 6 designed as a cylindrical container has a tangentially arranged inlet 6a and an outlet 6b emanating from the container tangentially, continuing the flow direction. This becomes clear in the top view of the separating device 6 (FIG. 2a).
- the mode of operation of the separating device 6 it is irrelevant which angle of inclination (as seen in a container cross-sectional plane) the inlet and outlet 6a and 6b to each other.
- the only decisive factor is that the rotational flow in the container can flow freely and thus inevitably into the outlet 6b in the direction of flow. It is also irrelevant for the mode of operation of the separating device 6 whether it is arranged vertically, horizontally or in any inclined position in space with respect to its container axis.
- the immersion tube 6c extends over the outlet-side boundary surface of the container of the separating device 6 in the direction of the Axis and concentrically to the lateral surface of the container, a piece engages in the container interior, on the other hand it is connected to the return line 7.
- Inlet and outlet 6a or 6b of the separation device 6 are integrated in the same way in the arrangement as is the case with the arrangement according to FIG. 1 and was already described there.
- liquid L1 liquid phase
- first conveying device 2 which can be a centrifugal pump
- gas-tight G gas phase
- the gas flow G can be adjusted by means of the metering device 10, which is generally designed as a dropper and control valve.
- the gas / liquid flow G * / L2 formed as a two-phase flow is combined with the gas flow G, the entire gas fraction G + G * continuing through the return line 7 at least some of them can already be redispersed in a carrier liquid L2.
- the unsuitable liquid flow L1 in the pipeline section la is combined with the gas / liquid flow (G + G *) / L2 in the return line 7; In their further course, both streams then pass through the static mixer 5 and possibly through the adjoining solution section 5a into the desired mass exchange with one another.
- the static mixer 5 and the possibly provided solution path 5a are acted upon by the flow which is set in the return line 7.
- the gas / liquid flow G * / L2 formed as a two-phase flow.
- the latter forms the so-called circulating flow, which is superimposed on the throughflow L1 within the pipeline 1 between the second introduction point 9 and the separating device 6, via the outlet 6b of the separating device 6, which is connected to the pipeline section 1b, a bubble-free liquid flow L1 * (Liquid phase) removed.
- the second conveying device 8 Since the second conveying device 8 has to deliver both bubble-free liquid L2 and pure gas G * under certain operating conditions in addition to the two-phase flow G * / L2, it is expediently designed as a self-priming centrifugal pump, preferably as a side channel pump. It goes without saying that the second conveying device 8 can also be substituted by another pump, such as, for example, by a rotating displacement pump, in particular an impeller pump or jet pump, provided that it has the required conveying properties.
- FIGS. 1 to 2a for carrying out the proposed method are particularly suitable for the so-called carbonation of beer.
- Carbonation of beer means that the beer is enriched with CO 2 gas, and today the brewery technology demands a complete solution of a given CO 2 amount in a certain amount of beer.
- Design criteria for such a carbonation plant are therefore, on the one hand, ensuring a certain CO 2 concentration in the beer and, on the other hand, its complete and thus bubble-free solution.
