Definitions

  • the present invention relates to a method for conveying a partially oxidized material for charging a printed reactor, in particular a gasification reactor.
  • From the gasifier reactor can be generated by the partial oxidation process gas subsequently, which then either used to synthesis gas for valuable chemicals or use a gas turbine under far more environmentally friendly alternative method, the starting materials mentioned under CO2 sequestration for energy production.
  • the starting materials In order to feed the starting materials into the reactor, the starting materials must experience an increase in pressure. As a rule, the starting materials are 2 to 5 bar brought over the reactor operating pressure before being transferred to the reactor.
  • the one common method is to first prepare a suspension of carbon powder and other partially oxidizable materials with a liquid such as oil or just water, which is then pressurized to higher pressure by a pump and then sprayed into the reactor.
  • the water Since a lot of coal is to be used as starting material for the gasification reactors, the water is usually used as an accompanying agent in these processes.
  • the feeding of water substantially reduces the reactor power since the water to be used reduces the required high reaction temperature due to the evaporation. This can only be compensated by combustion reaction of the coal to unwanted CO2, which reduces the reactor yield with respect to carbon used to form the desired main products CO and H2.
  • the coal dust or other feed material in different particle sizes and shapes in batch cycles from a non-pressurized main silo batchwise and periodically first transferred to an intermediate silo, which depending on the cycle with feed material filled, then time-printed with a carrier gas. Thereafter, the feed material is emptied into a pressure silo (called "Pressurized Surge Hopper") and then the intermediate silo is time-relaxed again before the next filling process is initiated.
  • a series of intermittently operating intermediate silos is necessary.
  • the intermediate silos must be designed on the one hand for receiving large quantities and on the other hand for pressure cycling. These factors require a high investment.
  • discontinuous process management requires a variety of valves and pipes with large diameters, which must be designed for a pressure cycling.
  • the circumstance is additionally increased by the fact that one must always receive the conveyed material with a carrier gas in the fluidized bed for handling large quantities of goods in large silos.
  • a large amount of inert gas is also necessary, as well as for the discontinuous pressure increase in the intermediate silos and the pressure silo.
  • inert gas compressor can easily be used without redundancy for cost and maintenance reasons, a complete shutdown of the system takes place as soon as the compressor fails. In the event of such a failure, comprehensive steps to re-start the entire system are indispensable.
  • the object of the present invention is to provide an improved process for the promotion of a partially oxidized material for charging a printed reactor.
  • the invention shows a process for the continuous dry promotion of a partially oxidized material for charging a printed reactor, in particular a gasification reactor available, wherein the material from a non-pressurized silo is fed to at least one extruder, whereby the material in the compression zone of the extruder Compression up to above the current operating pressure of the reactor learns.
  • As a partially oxidized material may be coal dust or carbon powder, granules, pellets of various starting materials or a mixture of different types of coal, refinery waste such as tar residues, pet coke, organic waste from chemical plants, dried powdered biomass, wood waste of various kinds, dried powdered black liquor Paper and pulp industry and other sustainable materials.
  • An extruder is a conveying device which picks up material according to the functional principle of a screw conveyor and presses it out of an outlet opening under pressure increase.
  • An extruder in this case has a worm shaft or worm, which is arranged rotatably in a worm cylinder.
  • the nominal diameter of the worm cylinder corresponds essentially to the outer diameter of the worm.
  • At one end of the screw is a drive, in most cases an electric motor with gear unit (extruder gear), which ensures the rotation of the screw.
  • Materials to be processed are usually fed to the screw on this side via a funnel from above.
  • At the other end of the worm cylinder is the outlet opening.
  • the auger itself is generally divided into three zones that perform different tasks.
  • the feed zone In the rear area of the worm cylinder is the so-called feed zone.
  • the material to be extruded is e.g. fed through a funnel and compacted.
  • the compression zone In which the material is further compressed by the reduced flight depth of the screw and thus the pressure necessary for the discharge is built up.
  • the discharge zone ensures a homogeneous material flow.
  • the extruder can be, for example, a single-screw extruder, twin-screw extruder (homokinous or countercurrent), multi-screw extruder, coked extruder or planetary extruder.
  • the promotion and the pressure build-up are caused by the friction of the mass rotating with the screw on the stationary housing wall (cylinder) in the single-screw and co-rotating twin-screw extruder - in this context one speaks of friction promotion.
  • the mass thus left in the rotation is pushed by the helical flights to the outlet opening.
  • twin-screw extruder the principle of forced extraction predominates.
  • the invention thus provides a continuous high-pressure delivery of dry material, in particular pulverized coal, for the partial oxidation in a coal gasification reactor for the production of the process gas.
