Definitions
- the invention relates to a method and a plant for at least partial Verga- solution of solid organic feedstock, in particular of biomass, with a low-temperature gasifier and a high-temperature gasifier.
- BTL Biomass to Liquids method
- GTL gas-to-liquids
- CTL coal-to- Liquids
- An example of a plant for the production of BTL fuels is in Kiener, C. and Bilas, I .: Synthetic biofuel of the second generation. World's first commercial BTL production plant. Energy 2.0, July 2008, p. 42-44.
- Processes and plants for the at least partial gasification of solid organic feedstock are also known for example from EP 0 745 114 B1, DE 41 39 512 A1 and DE 42 09 549 A1.
- the present application relates in this case to such processes or plants which have a low-temperature gasifier and a high-temperature gasifier, as explained below. Compared to other methods, these enable u.a. a lower consumption of feed and have a higher cold gas efficiency.
- the feedstock such as biomass
- a gasification agent at temperatures between about 300 ° C and 600 ° C to coke (in the case of biomass so-called biococ) and
- Smoldering is known to be characterized by substoichiometric oxygen supply and thus incomplete combustion at comparatively low temperatures.
- the carbonization gas is then transferred to a combustion chamber of the high-temperature gasifier and there with an oxygen-containing gas, for example with more or less pure oxygen, but also with air and / or oxygen-containing exhaust gases, e.g. from gas turbines or internal combustion engines, partially oxidized. Heat released by this oxidation causes the temperature to rise to 1,200 ° C. to 2,000 ° C., for example 1,400 ° C. Under such conditions, aromatics, tars and oxo compounds contained in the carbonization gas are completely decomposed. As a result, a synthesis gas is formed, which essentially only contains carbon monoxide, hydrogen, carbon dioxide and water vapor. The synthesis gas can also be referred to as (synthesis) raw gas at this point.
- an oxygen-containing gas for example with more or less pure oxygen, but also with air and / or oxygen-containing exhaust gases, e.g. from gas turbines or internal combustion engines, partially oxidized. Heat released by this oxidation causes the temperature to rise to 1,200 ° C.
- the synthesis gas produced in this way can be brought into contact with coke from the low-temperature gasifier.
- the coke may be previously treated separately (e.g., by grinding and sifting) and then introduced into the quench unit.
- chemical quench By endothermic reactions between coke and synthesis gas (so-called chemical quench) the latter is cooled to a target temperature of about 900 ° C. This also causes a partial conversion of the carbon dioxide to carbon monoxide.
- the carbon monoxide-rich synthesis gas produced in this way can then be further conditioned.
- the conditioning includes, for example, a further cooling, dedusting, densification and / or the separation of residual carbon dioxide.
- the conditioning comprises in particular the separation of residual coke from the synthesis gas. This is accomplished in practice by means of a cyclone and a downstream filter. The residual coke thus separated is then cooled in cooling screws and discharged from the pressure chamber via a container lock. discharged. A portion of the residual coke is introduced via container locks back into the pressure chamber and fed through a dense phase current to the burner (Hochtemperaturvergaser). During the cooling of the synthesis gas, however, there is a condensation of alkalis on the residual coke, so that not all the residual coke can be recycled to avoid too much alkali concentration in Hochtemperaturvergaser. In conventional systems, therefore, a portion of the alkali-loaded residual coke is removed from the system or discarded.
- the invention is based on a known process for the at least partial gasification of solid organic feedstock, for example biomass.
- a tarry carbonization gas is obtained by smoldering in a low-temperature gasifier, as explained above.
- the carbonization gas is then reacted in a high-temperature gasifier by partial oxidation and then partial reduction to a synthesis gas and further processed downstream of the high-temperature gasifier in appropriate treatment facilities.
- the synthesis gas is cooled after leaving the Hochtemperaturvergasers first in a cooling device to a temperature of about 600-800 ° C.
- the cooling takes place according to the invention in such a way, ie to a temperature such that a substantial proportion (in particular at least% by weight 10%,% by weight 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90%) of the alkalis present in the synthesis gas remain in the gaseous phase, but coke particles are already no longer sticky.
- a substantial proportion in particular at least% by weight 10%,% by weight 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90%
- the alkalis present in the synthesis gas remain in the gaseous phase, but coke particles are already no longer sticky.
- the stickiness of the coke particles is too pronounced, which can lead to problems in further handling.
- the actual temperature to which it is cooled may depend on the composition of the feed and / or environmental conditions. To set a suitable temperature can be used on empirical values. It is also conceivable to provide corresponding sensors or measuring devices which detect the phase of the alkalis or the stickiness of the coke particles, and give the detected values to a control device, via which the temperature can be set.
- the invention is characterized in that a coarse fraction of coke particles is separated from the synthesis gas in a cyclone device provided downstream of the high-temperature gasifier and the cooling device, a fine fraction of the coke particles passing through the cyclone device with the synthesis gas.
- the fine fraction of coke particles leaves with the synthesis gas containing the gaseous alkalis, the cyclone device and can be removed from the system.
- the coarse fraction of the coke particles which is substantially alkali-free, can be recycled to the high temperature gasifier.
- the synthesis gas passing through the cyclone device is further cooled in a cooler provided downstream of the cyclone device.
- the coke particles of the fine fraction present in the synthesis gas in this case have, for example, diameters of 0.1 to 10 ⁇ m.
- the alkalis also present in the synthesis gas condense on the surface of these coke particles.
- a targeted separation of the alkalis takes place on the particles of the fine fraction, which passes through the cyclone device with the synthesis gas stream.
- the particles of the fine Fraction are particularly well suited for alkali deposition as they have a relatively large surface area with relatively low mass. As a result, a relatively large surface area is available for the condensation, the calorific value loss being relatively low.
- the coarse fraction of the coke particles in particular taking advantage of gravity, transferred in a buffer tank and then in a vertically arranged standpipe, wherein the height of the standpipe is selected so that in the lower part of a for fluidization tion sufficient pressure is provided to facilitate dense phase conveying and to ensure entry of the coke provided thereby into the high temperature gasifier.
- the diameter of the standpipe is chosen so that bridging of the coke particles of the coarse fraction can be avoided.
- the lowest part of the standpipe can be formed with a further reduced diameter, whereby an increase in the flow velocity can be provided, so that the required for the dense phase fluidization fluidization is ensured only in this lowermost region of the standpipe.
- the residual coke present in the buffer tank or in the standpipe acts as a pressure barrier, so that coke recycled to the lowermost part of the standpipe into the high-temperature gasifier can be conveyed under a suitable delivery pressure.
- a suitable delivery pressure Compared to the pressure in the cyclone device prevails in the lowest part of the standpipe preferably an overpressure of about 0.2 to 1 bar.
- recycle of coke over the buffer vessel and standpipe is performed at a temperature substantially equal to the temperature in the cyclone device.
- coke can be recycled to the high temperature gasifier at a very high temperature, whereby the efficiency of the gasification is improved accordingly, for example, 0.5% to 1%.
- Figure 1 shows a system which is adapted to carry out a method according to the invention, in a schematic representation.
- FIG. 1 shows a system which is set up to carry out a method according to the invention and designated overall by 10.
- the system 10 comprises a low-temperature gasifier 1 and a high-temperature gasifier 2.
- a feedstock such as biomass such as wood or corresponding waste, as previously explained, be fed (by means of arrow 1 1 illustrated).
- oxygen can be fed in via a line 12.
- the low-temperature gasifier 1 is set up to blaze the solid organic feedstock A.
- the low temperature carburetor 1 externally, for example, with waste heat of Hochtemperaturvergasers 2, to a suitable temperature, for example 300 ° C to 600 ° C, heated.
- starting torches of the high-temperature gasifier 2 can also be used.
- a carbonization B can be discharged from the low-temperature carburetor 1 and transferred to the high temperature carburetor 2.
- the high temperature carburetor 2 is formed in two parts. It comprises an oxidation unit 21 and a quench unit 22.
- the carbonization gas B is partially oxidized with an oxygen-containing gas supplied, resulting in temperatures of, for example, 1400 ° C. to 2000 ° C.
- a synthesis gas is obtained.
- This synthesis gas contained coke particles have due to the high temperature on a strong stickiness.
- the synthesis gas obtained at the outlet of the high-temperature gasifier 2 is fed to a cooler 30, where it is cooled to a temperature of 600 to 800 ° C., for example.
- This temperature is chosen so that present in the synthesis gas alkalis remain in a substantial proportion in the gaseous phase, and in the synthesis gas contained coke particles have no more stickiness.
- the synthesis gas is fed to a cyclone device 4 where a coarse fraction of the residual coke is deposited in a buffer vessel 15, while the synthesis gas, which among other things a fine fraction of Koksparti- no (for example, with diameters 0.1-10 ⁇ ) and receives gaseous alkalis is supplied via a line 17 to a further cooling device 19.
- the synthesis gas is cooled in such a way, for example, to temperatures of 100 ° C to 200 ° C, so that the alkalis on the particles of the fine fraction of the coke particles condense. This contaminated with alkalies residual coke z. B. by means of (not shown) wet gas scrubbing from the syngas stream.
- the diameter of the standpipe is chosen so that bridging of the coke particles can be avoided. Preferred diameters of the standpipe here are 300 mm to 1,000 mm.
- the height h of the standpipe for example 5 to 50 meters, is selected such that a sufficiently large pressure build-up is achieved during fluidization of the coke particles present in the lowest part of the standpipe, so that dense phase conveying by means of a suitable conveying gas (inert gas, For example, C02) can be operated.
- a suitable conveying gas for example, C02
- Such a dense phase conveying represents a particularly effective form of conveying the coke back into the high-temperature gasifier.
- the lowermost part 25a of the standpipe 25 is formed by reducing the diameter so that here the flow rate of the gas supplied for the fluidization is sufficient for the larger above it Cross section but not.
- the plant shown is thus able to remove specific alkalis from the residual coke.
