Definitions

  • the subject matter of the application relates to a method and an arrangement for operating a particulate feed system for the pressurized gasification of pulverized coal, having the features set forth in the claims.
  • Nitrogen from the air separation unit is normally used as the inerting and conveying medium in pneumatically operated particulate feed systems for high-pressure gasification plants using pulverized coal.
  • This process variant has proved its worth both in particulate feed systems for injecting pulverized coal into blast furnaces and also for high-pressure gasification plants using pulverized coal, and is to a large extent mature technology.
  • the lock hopper depressurization gas and the surplus gas accumulating under certain operating conditions in the metering vessel is advantageously de-dusted in special filter units already under elevated operating pressures before being vented to the atmosphere.
  • the particulate feed systems based on dense-phase pneumatic conveying operate with very high loading ratios, the nitrogen introduced into the gasification systems in many cases exceeds the permissible limits. This is also caused by increasing process pressure in the majority of applications.
  • Particularly for pressurized gasification of pulverized coal with the objective of obtaining synthesis gas for the production of different hydrocarbons there arises a requirement to limit the nitrogen content of
  • the object to be achieved by the subject matter of the application is to further develop a method and an arrangement of a particulate feed system for the pressurized gasification of pulverized coal such that the nitrogen introduced into the downstream gasification system and the attendant disadvantages thereof are avoided.
  • carbon dioxide CO 2 is fed to the feed lock hopper as an inerting and conveying medium and to the metering vessel as a fluidizing medium.
  • the sections of the plant that are operated with essentially pure carbon dioxide are heated to the point that a temperature above the threshold of the two-phase region is obtained.
  • the invention advantageously makes use of the fact that not all the components need to be operated with carbon dioxide; instead heated nitrogen is fed to the storage bin as an inerting and disaggregating medium—with reduced cost/complexity compared to carbon dioxide.
  • FIG. 1 shows a block diagram of a particulate feed system according to the invention.
  • Heated nitrogen N 2 can be fed as an inerting and disaggregating medium to a bin BK for storing solid matter FS such as pulverized coal, which bin is at ambient pressure and can be heated.
  • the solid matter can be fed via a conveying device to a feed lock hopper SES which is at a high operating pressure of e.g. 40 bar.
  • Carbon dioxide CO 2 can be supplied to the feed lock hopper as an inerting and conveying medium at a temperature above the threshold to the two-phase region at high operating pressure.
  • the depressurization gas is drawn off, expanded to ambient pressure via a multi-stage depressurization device mEV and de-dusted in a downstream filter F at ambient pressure.
  • the solid matter is transferred by gravity flow from the feed lock hoppers to the metering vessel DG via an adequately dimensioned downcomer. Two to four lock hoppers are used for each particulate feed system.
  • Carbon dioxide is used as a fluidizing gas.
  • a partial fluidized bed is created by the fluidizing gas in the lower part of the metering vessel.
  • the pulverized coal is converted from the particulate feedstock state to the fluidized bed and therefore simultaneously to the conveying state.
  • the gas entrained with the pulverized coal at the conveying line inlet FLE to the reactor consists virtually totally of this gas component.
  • Carbon dioxide is likewise used as the injection gas.
  • the injection gas is introduced into the pulverized coal conveying lines. Injection gas feeds may be may be required in order to detect disturbances in the pulverized coal supply to the reactor sufficiently quickly.
  • the requirement to limit the nitrogen content in the product gas obtained from pressurized gasification of pulverized coal is taken into account by using carbon dioxide as the inerting and conveying medium in the particulate feed system.
  • the carbon dioxide is acquired at a sufficiently high temperature even at the plant periphery.
  • the cooling of the gas during storage, transport and the process-specific use thereof must be counteracted by a suitable heating system.
  • the pulverized coal bin operating at ambient temperature and supplied with nitrogen as an inerting and disaggregating medium, is heated.
  • the supplied nitrogen is also heated in order to prevent the pulverized coal from cooling down e.g. in the event of lengthy plant downtimes.
  • continuous heating is provided in the process sections gas storage, transport and metering system itself.
  • the pressure of the slightly dust-bearing depressurization gas is reduced via multi-stage depressurization devices mEV.
  • the depressurization gas is subsequently de-dusted in a filter F operating at ambient pressure.
  • the section of pipework between lock hopper and depressurization device is heated in order to compensate the polytropic depressurization cooling and maintain the permissible operating conditions of the depressurization filter.
  • the depressurization device is designed such that depressurization noise is simultaneously reduced.
  • So-called silencer plates for example, which are well-known in technical circles, are used as depressurization devices. These bring about a reduction in the depressurization noise, on the one hand, by multi-stage depressurization and, on the other, by spreading the total bore cross-section required over a plurality of smaller bores.
  • a wear-protected control valve with downstream silencer can also be used. If these measures are insufficient, additional sound insulation measures can be employed, e.g. by means of a sound-absorbent cladding.
