- an acetogenic bacterium is preferably used, which converts metabolites of 1, 3-propanediol producers with a molecular weight ⁇ 200 g / mol in acetic acid, H 2 or CO 2 .
- the acetic acid formed in these reactions diffuses through the membrane 2.1 into the reactor chamber 2.3. There it serves as a substrate of methane bacteria. For example, the following reaction can take place:
- Slow-growing methanogens are cultivated in the reactor chamber 2.3, for example an archaeon of the genera Methanosaricina and Methanothrix, especially M. Mazei, M. barkeri and / or M. acetivorans and / or a mixed culture which at least partially contains these genera. Inhibition of the 1,3-propanediol producers by metabolites such as acetic acid is abolished because they are converted from methane bacteria to methane.
- the methane passes through the line section 3.7 in the combined heat and power plant 7 where it is converted into electricity and heat.
- the purification of the fermentation supernatant is preferably carried out by sedimentation, flocculation, centrifugation, filtration, evaporation, distillation, extraction, absorption, adsorption or membrane separation.
- the bioreactor 2 a further bioreactor as described in Chapter 6 can be followed, in which the excess glycerol is converted to additional 1, 3-propanediol, and thus no separation between glycerol and 1, 3-propanediol is necessary.
- the 1, 3-propanediol-containing fermentation broth passes through the line section 3.2, in which a filter 9 can be installed, from the reaction chamber 2.2 for thickening in the evaporator. 4
- the electricity generated in the cogeneration plant 7 feeds the compressor 5 in the line section 3.3 via the line section 3.8.
- the compressor 5 generates a vacuum in the evaporator 4 via the line section 3.3. In this way, the fermentation broth in the evaporator 4 is thickened.
- the separated vapor condensate passes via the line section 3.3 in the reactor chamber 2.2 for 1, 3-propanediol production. In the reactor chamber 2.2 for 1,3-propanediol production, the vapor condensate dilutes the glycerol, since at a low glycerol concentration the 1, 3-propanediol producers grow better.
- a nitrogen sink may be provided in the vapor condensate recycle.
- the thickened 1, 3-propanediol-containing fermentation broth enters the column 6.
- the heat generated in the energy converter 7 passes through the line section 3.10 in the heating element 6.1 of the column 6 and heats the thickened 1, 3-propanediol-containing fermentation broth. Thereby the more volatile 1, 3-propanediol is separated.
- the column bottom contains the unreacted glycerol and the fermentation salts, which can be partially reintroduced via the line section 3.5 into the reactor chamber 2.2 of the bioreactor 2. From the outlet line 3.6 at the top of the column 6, the 1, 3-propanediol produced can be removed.
- the power from the cogeneration unit can be removed externally.
- the heat from the combined heat and power plant can be taken externally via line section 3.11.
- Methanol which is usually present in technical glycerol, is degraded by the methane bacteria present in the bioreactor.
- the two anaerobic fermentations are connected in succession.
- the fermentation of glycerol takes place in the bioreactor 10 for 1, 3-propanediol production.
- the fermentation of the metabolites to methane takes place in the bioreactor 14.
- the purification of the 1,3-propanediol takes place in 3 separation stages 11, 12, 13.
- the vapor condensate separated off in the first separation stage 11 is, analogously to the first embodiment, transferred via a conduit section 3.26 into the bioreactor 10 for the dilution of the glycerol.
- the 1, 3-propanediol production is inhibited mainly by organic acids such as acetic acid and butyric acid and ethanol. These metabolites are removed in the first column 12 and transferred to the bioreactor 14, where they are converted to methane.
- the difference between the two embodiments is that in the dialysis reactor the hydrogen on the 1,3-propanediol producer side has to be consumed by homoacetate fermenter. This is done by the methanogens in a reactor without a dialysis system. The methanogens are a more effective hydrogen sink than the homoacetate fermenter.
- the waste heat generated in the combined heat and power plant 15 passes through the line section 3.23 in the second and the third separation stage 12, 13 where they used to separate the volatile metabolites (in column 1) and for separating the product of 1, 3-propanediol (in column 2) becomes.
- the device 2 operates analogously to the method described in the first embodiment.
- the energy potential of the waste materials is transformed into an energy source which is easy to handle and easy to separate off. leads.
- This energy source is methane and is converted in an energy converter into electricity and heat, which is used in the process.
- This local utilization of the waste heat achieves a high degree of efficiency and the costs for the production of 1,3-propanediol are kept low.
- a bioreactor with a membrane will be described.
- a bioreactor without membrane is used in this device.
- This last-mentioned embodiment is particularly advantageous if the by-products of the producers for the production of the respective product can be reacted directly by the methanogens in methane.
- This is particularly advantageous when a larger amount of hydrogen is produced as a by-product, since due to the poor solubility of the hydrogen in the fermentation liquid, the hydrogen hardly diffuses across the membrane into the chamber 2.3, but escapes from the reactor with the exhaust gas stream.
- the resulting dissolved hydrogen concentration in chamber 2.2 will be greater than 10 Pa due to the diffusion resistance across the membrane and thus toxic for some processes (for example, propionic acid oxidation).
- 1, 3-propanediol and methane can be prepared in an unsterile fermentation with a co-culture of 1, 3-propanediol producers, acetogenic and methanogenic microorganisms.
- 1, 3-propanediol-forming microorganisms and the metabolites utilizing acetogenic and methanogenic microorganisms can be found in the same pH values and temperatures are cultivated.
- the non-sterile process control makes this co-cultivation fermentation particularly advantageous due to the lower cost.
- the bioreactor can be run with relatively short residence times of the biomass, which are flushed out of the bioreactor harmful to the process microorganisms, such as sulfate-reducing microorganisms.
- the substrate used is a glycerol solution, for example technical glycerol.
- the anaerobic, 1, 3-propanediol producers that grow in the bioreactor produce from the glycerol as metabolic end products acetic acid, butyric acid, hydrogen and CO2, ethanol, lactic acid and 1, 3-porpandiol.
- energy is generated in the form of ATP but at the same time NADH is also oxidized to NAD.
- propane-diol In order to maintain the redox balance, propane-diol must always be formed in stoichiometric amounts, since the formation of propane-diol is the only reaction in which NAD can be reduced to NADH again.
- glycerol can be supplied in excess.
- the additional introduction of a methanogenic and acetogenic coculture into the same reactor with the 1, 3-propanediol producers can inhibit the 1, 3-propanediol producers inhibiting metabolites of 1, 3-propanediol production, such as acetic acid, butyric acid, ethanol, Lactic acid and hydrogen, are converted into methane and CO 2 , which do not inhibit and leave the system in the headspace of the bioreactor, from where they are derived.
- the fermentation continuously withdrawn the inhibitors and favors the production of 1, 3-propanediol.
- the co-culture is composed of clostridia, acetogenic and methanogenic bacteria.
- a separation of the readily volatile constituents takes place first, followed by a separation of the low-volatility constituents (glycerol, salts) in distillation columns.
- the low-volatility constituents glycerol, salts
- 3-Propanediol and glycerol are hydrophilic and have very high boiling temperatures, which is why the separations must be carried out at very high bottom temperatures.
- Glycerol decomposes at about 180 0 C to acrolein and water. Both decomposition products are volatile (boiling point 52 0 C and 100 0 C)
- the high-toxic acrolien can also polymerize in the separation column.
- the 1, 3-propanediol-glycerol separation is therefore carried out in the first and second embodiments in a high vacuum, so that the decomposition reaction can not occur.
- the anions of the metabolites acetic acid, lactic acid, butyric acid
- the salts may be concentrated, so that an additional salt sink is necessary.
- the purification can also be carried out particularly economically without glycerol-propanediol separation and, if appropriate, a salt sink.
- This postreactor can be carried out, for example, as a stirred tank cascade or fed batch reactor.
- This secondary reactor is preferably designed as a flow tube. In this Nachreaktor no fresh substrate passes; the existing biomass only reduces the existing substrate and metabolite surplus and then starves.
- the typical propanediol formers have a very low monod constant for glycerin (about 0.005 g / L), which means that the microorganism metabolism is not appreciably slowed as the glycerol concentration decreases.
- the post-reactor must be routed so that the biomass does not degrade 1, 3-propanediol.
- sulfate-reducing microorganisms could degrade propanediol anaerobically by oxidizing 1,3-propanediol back to 3-hydroxypropanal to give 3-hydroxypropionic acid (hydracylic acid).
- This is then further oxidized via acetaldehyde to acetic acid, wherein the electrons necessary for oxidation relate the sulfate-reducing microorganisms from the reduction of the sulfate to H 2 S.
- This reaction is inhibited if no sulfate is present in equimolar amounts.
- 1,3-propanediol is anaerobically degradable even in the absence of sulfate.
- the postreactor is therefore designed so that the 1, 3 Propanediol-degrading microorganisms are flushed out of the system.
- the external conditions such as residence time, hydrogen partial pressure, temperature, pH, are adjusted so that this organisms have a higher generation time than their hydraulic residence time in the reactor.
- inhibitors which selectively inhibit the growth of the 1,3-propanediol-degrading microorganisms.
- 1,8-dihydroxyanthraquinone (EP0525073) or molybdate may be added to inhibit sulfate-reducing microorganisms.
- FIG. 6 shows a preferred embodiment for a purification of 1, 3
- This purification can be carried out for processes in which 1, 3-propanediol and methane are produced in the same bioreactor, as well as for two-stage processes such as, for example, Example 2, in which the methane production takes place in a second bioreactor.
- the plant comprises a bioreactor 2 in which glycerol is fed via the feed line 25 and converted to 1,3-propanediol.
- the methane formed is withdrawn via the exhaust pipe 22 from the bioreactor 2.
- the fermentation broth with the excess glycerol and the not yet utilized inhibiting metabolites is passed via the discharge line 26 into the secondary reactor 20.
- the post-reactor 20 consists of three cascaded flow tubes.
- the methane formed from the remaining metabolites is withdrawn via a degassing line 21 from the secondary reactor 20.
- the postreactor 20 is guided so that the 1, 3-propanediol is not degraded from the bioreactor 2.
- the fermentation supernatant of the postreactor 20 remaining after the conversion of the excess glycerol is removed for protein removal via the line 23 through the filter 17, which may be embodied as an ultrafiltration unit.
- the proteins from the fermentation broth can precipitate in the distillation column and must therefore be separated beforehand via the discharge line 27.
- the filtrate from the filter 17 is introduced into a vacuum distillation column 4. directed to separate water and volatile metabolites of 1, 3-propanediol and the salts.
- the condensate of water and the readily volatile metabolites drawn off via the top of the vacuum distillation column is returned to the bioreactor 2 via the return line 24 in the single-stage process shown here.
- the water and the volatile metabolites are transferred to a second bioreactor for methane fermentation.
- the residue accumulated in the bottom of the distillation column 4 is finally passed into an evaporator 18 in order to separate the 1,3-propanediol from the salts.
- the remaining salts in the evaporator 18, are removed through the drain 28.
- FIG. 5 shows two mathematical balance models for the mass balance of liquids (upper equation system in FIG. 5) and of gaseous substances (lower equation system in FIG. 5).
- FIG. 4 shows a block diagram of the mass flows on the basis of the first exemplary embodiment.
- a mass balance of 1, 3-propanediol production is created.
- the balance includes the following species: water, glycerol, 1,3-propanediol (PDO), biogas (BG), free metabolites.
- Aqueous glycerol solution is added to the reactor (m ⁇ ).
- the effluent and biogas stream is considered a stream (m1) summarized.
- a recycle stream is diverted from the reactor and added to the evaporator. At the head of the evaporator sits a thermocompressor and creates a vacuum.
- the vapor condensate (m3) is returned to the reactor for diluting the glycerol.
- Equation (I) describes the balance of the incoming and outgoing liquids in the reactor.
- Aqueous glycerol solution m ⁇ is fed to the reactor.
- the unavailable effluent stream m1 is discharged from the reactor.
- the circulation flow m2 is discharged.
- the vapor condensate m3 from the first column is fed to the reactor.
- the sum of the supplied material flows m ⁇ , m3, m7 into the reactor is equal to the sum of the discharged material flows m1, m2 from the reactor.
- the second equation (II) describes the balance of the liquids in the first column.
- the circulating stream m2 to be evaporated is fed to the first column.
- the vapor condensate m3 formed during the evaporation is removed from the column.
- the thickened bottom stream m4 is discharged from the column.
- the supplied stream m2 in the first column is equal to the sum of the discharged streams m3 and m4 from the first column.
- Equation (III) describes the balance of the incoming and outgoing liquids of the second column.
- the thickened bottom stream m4 is fed to the second column.
- the propane-water-metabolite mixture m5 is discharged via the top of the second column.
- the aqueous glycerol-propanediol salt solution m6 is discharged from the second column. This can also be returned to the reactor, but this is not provided in this balance model.
- the supplied stream m4 corresponds to the sum of the two discharged streams m5, m6.
- Equation (IV) describes that the aqueous glycerol solution m ⁇ is the only externally supplied educt m ⁇ np ut.
- Equation (V) describes how high the proportion of the circulatory flow m2 introduced into the first column is, which is introduced as recycled water m3 back into the reactor.
- Equation (VI) describes how much propane-water-metabolite mixture m5 is recovered from the supplied bottom stream m4.
- Equation (VII) represents the conversion of the starting materials into products in bioreactor 2.
- equation 2 of FIG. 5 the balance model of the gaseous substances corresponds to the balance model of the liquids. It differs only in equation (VI-II), which reads as follows:
- the power or heat supplied to the compressor of the first column is calculated using Equation 3. To evaporate a ton of water with the thermocompressor about 20 kWh are needed.
- the electrical energy required for the evaporator of the second column is given by equation 4. It is calculated from the heat of vaporization of the individual components of the discharged aqueous streams m6, m5.
- the mass-related enthalpy of vaporization of water W r as Se r is used for the metabolites, and water.
- the enthalpy of vaporization of propanediol r PD o is used.
- Equation 5 The efficiency of the plant or the propanediol yield m5 based on the supplied glycerol solution is described by Equation 5.
- Equation 6 describes the efficiency between the energy dissipated in the aqueous propanediol m5 and the energy supplied in the aqueous glycerol stream m ⁇ . From this it follows that 27% of the energy of the glycerol m ⁇ is converted in the produced propanediol m5.
- Equation / describes the efficiency between the energy dissipated in the biogas m1 and the energy supplied in the aqueous glycerol stream m ⁇ . It follows that 65% of the energy of the glycerol m ⁇ , based on the calorific value, are converted into biogas m1.
- Equation 8 gives the energy losses in the plant. Adding the energies used and subtracting them from the energy used results in the energy potential contained in the by-products.
- the unused energy in the glycerol-propanediol salt solution m6 is 8% of the input energy of the glycerine m ⁇ used.
- the simplified mass balance of propanediol production can be solved.
- the solution is based on the assumption that the glycerin solution contained in the glycerol solution supplied to the reactor contains 40% of glycerol and 60% of water.
- the glycerine solution comes from the waste stream of a biodiesel plant.
- the first separation stage 4 about 80% of the water of the circulated stream m2 supplied is evaporated. Also evaporated is 99% of the biogas contained in the circulating flow and 80% of the contained metabolites. These substances are recycled as vapor condensate m3 in the reactor.
- waste (m1, liquid) from the reactor Approximately 1% of the total mass is discharged as waste (m1, liquid) from the reactor to prevent excessive impurities.
- the combined heat and power plant assumed an electrical efficiency of 40% and a thermal efficiency of 45%.
- the thermal steamer requires in the present example an electrical power of 0.46 MW. This corresponds to approximately 23% of the amount of electricity generated from methane in the combined heat and power plant. As a result, 1.67 MW of electricity can be fed into the grid.
- the bottom evaporator requires approximately a temperature of about 100 0 C to 200 0 C.
- the temperature of the exhaust gas of the cogeneration plant is about 300 0 C to 400 0 C and the cooling of the engine of the combined heat and power plant gives gas at a temperature of about 90 0 C off which can be used to heat the second column.
- the sump evaporator requires 3.74 MW of heat. This corresponds to about 156% of the available heat. This means that additional heat must be fed into the system to the tune of 1.61 MW. Alternatively, part of the excess flow is used to operate a heat pump which, starting from the temperature level of the engine cooling water, provides high temperature heat to the sump evaporator. The plant would then be energy self-sufficient.
- the method and apparatus described above may also be used to make other products. It is always envisaged to convert acidic, reaction-inhibiting by-products into methane and to feed energy from the methane into the process or to utilize it.
