Definitions

  • the invention is directed to a method and to a system for supplying a reactor for the production of raw synthesis gas from fine-grained to dust-like fuel.
  • Publications 10 2007 020 332 A and 10 2007 020 333 A disclose promotions with a mixture of one and two CO 2 -GaS or by means of pure CO 2 , wherein in one case a second gas has to be provided, namely the N 2 , while in the other case pure CO 2 has the disadvantage that always temperatures above the limit to the 2-phase region must be complied with.
  • the promotion by means of CO 2 gas is also known, for example, from WO 2008/025556 A.
  • More problematic than the 2-phase state of CO 2 is the formation of water ice from the moisture which diffused from the solid into the lock gas in the lock container. Particularly low temperatures, for example, well below 0 0 C, occur in the final phase of the relaxation, whereby water ice can be formed.
  • the object of the present invention is to design the fuel supply system of a pressure gasification plant according to the invention such that the introduction of nitrogen into the raw gas is minimized or completely avoided, in order to correspondingly reduce the associated disadvantages.
  • CO 2 existing gas For supplying the fuel between the plant components and from the storage tank to the gasification reactor, a predominantly from CO 2 existing gas (more than 95 vol .-% CO 2 with admixtures, such as H 2 , CO, N 2 , hydrocarbons. Like.) becomes.
  • the invention also provides a system, which is characterized in that feeds of predominantly CO 2 existing gas are provided, namely
  • the dust-like fuel 3 is temporarily stored in a storage container 2 and transferred from there via a connecting line 4 to the lock container 5.
  • the pressure of the lock container 5 must first be reduced to the pressure level of the storage container.
  • the gas 6 flowing out of the lock containers is first heated 7, then dedusted 8 and then released.
  • the gas is significantly cooled due to the isotropic or polytropic relaxation, whereby ice formation from the water vapor, which comes from the residual moisture of the coal, and condensation of CO 2 could disturb the process.
  • the lock container is cyclically faced with low temperatures, whereby the container wall is subjected to mechanical stress, resulting in a cyclic process fatigue of the material. To avoid this, the lock container is heated from the outside electrically or with a medium.
  • the heated gas can be dedusted and further expanded without difficulty. Under increased pressure, the heat exchange is very intense, so that a relatively small heat exchanger is sufficient.
  • an MP buffer tank 10 is first filled at medium pressure level (MP)
  • an LP buffer tank 11 is filled at a lower pressure level and the remainder of the gas is expanded 12 and usually released into the atmosphere, either directly or through the filter , with which the solid content of the gas can be further reduced.
  • the gas from the LP buffer tank 11 is used for the inertization 15 and the fluidization 16 of the reservoir.
  • a portion of the gas 17 may also be used for other applications at a lower pressure level, such as for inerting the grinding plant.
  • the stored in the MP buffer tank 10 gas is used here for partial covering the lock container 20, the rest can be used for example advantageous for the treatment of the deposited from the raw fly ash, whereby the inert gas demand and the C0 2 emission into the atmosphere even more significantly reduced can be.
  • the feed tank 29 is permanently at operating pressure and continuously supplies the burners 31 of the gasification reactor 32.
  • the feed from the feed tank is effected by adding loosening and fluidizing gas 37 and the addition of further transport gas 38 into the burner line 30.
  • the predominantly carbon dioxide gas 21 is obtained in gasification plants usually from the downstream gas scrubbing, the use of nitrogen is provided for starting operation of the total Anläge, which can be easily stored for this purpose, for example. As soon as the operation has commenced so far that the carbon dioxide is separated in the gas cleaning, a switchover to carbon dioxide-containing gas takes place for the further control operation.
  • the carbon dioxide-containing gas obtained in the gas purification usually contains small amounts of components, such as carbon monoxide, hydrogen sulfide, hydrocarbons, etc. Since parts of the gas used for the smuggling are discharged to the environment, in the exemplary embodiment in Figure 1, the streams 33, 34th , possibly 36, a previous cleaning of the carbon dioxide-containing gas is required, so that the permissible emission limit values are not exceeded.
  • the gas obtained in a solvent (methanol, MDEa, etc.) based gas purification contains, in addition to the main constituent CO 2, for example, the following volume fractions of other components: CO ⁇ 1%, H 2 ⁇ 1%, N 2 ⁇ 1% and traces of methane, hydrogen sulfide , Argon and the solvent used. If a kriogenic liquid nitrogen scrubbing is used for gas purification, the nitrogen content is significantly higher, eg 15% vol.
  • the high CO content is harmful to the environment.
  • a low CO fraction eg ⁇ 100 ppmv, is used for the smuggling and then released and the other high CO fraction is either treated or recycled.
  • FIG. 1 shows a separation between the carbon dioxide-containing gas used for lock-up, for lock tank coverage, for solids transport from the lock tank to the storage tank and for pressure maintenance in the storage tank 21 and the carbon dioxide-containing gas used for fuel delivery to the burners 25.
  • the above-mentioned cleaning is required in terms of emission limit values because most of the gas is discharged to the environment.
  • unpurified gas can also be used for the loosening and fluidization 37 and for the transport gas 38, since it enters the carburetor with the fuel via the burners and participates in the running reactions at high temperatures there.
  • FIG. 1 shows by way of example an advantageous embodiment of the invention. Further advantageous variations are conceivable, such as the use of only one buffer container. This can be advantageous if further consumers do not need MP Recyclegas 19, for example, if due to the design of the gasification reactor no fly ash treatment must be provided.
