Definitions
- the invention relates to a method for the partial decoupling of Smoldering gas generation and smoldering gas consumption in a pyrolysis plant, which is generated in a pyrolysis reactor Carbonization gas is fed to a gas converter for conversion into cracked gas and the cracked gas as an environmentally friendly fuel is used.
- a Gas converter for conversion into cracked gas and the cracked gas as an environmentally friendly fuel is used.
- a Device suitable for carrying out the method.
- Fission gas is available, which can be used in sync with the generation got to.
- Generation and demand for pyrolysis gas are in usually out of sync as they are functions more independent Processes can be. With an excess supply of fission gas must therefore be flared if necessary.
- the inventor has the Task, a method and a device of to create the kind mentioned above, with which a handling of the pyrolysis oil is not required and which one is optimal Allow use of a commercially available gas converter.
- the object is achieved according to the invention solved in that the exiting from the pyrolysis reactor Smoldering gas flow before it enters the gas converter Adaptation of the cracked gas stream emerging from the gas converter to the respective fuel requirements with lower fuel requirements by at least partially condensing Smoldering gas reduced and with higher fuel requirements additional vaporization of condensed carbonization gas increased becomes.
- That part of the pyrolysis gas is called permanent gas understood that remains gaseous even at room temperature.
- pyrolysis gas is cracked on a high-temperature coke bed at 1200 ° C to CO, CO 2 , CH 4 and H 2 . After acid separation, this so-called cracked gas is available as an environmentally friendly fuel using commercially available gas scrubbing, for example to generate process heat.
- inventive sen process is carried out by the condensation of carbonization gas indirect cooling with water and the evaporation of condensed Smoldering gas or pyrolysis oil is preferably by indirect heating with hot air.
- condensation of carbonization gas indirect cooling with water and the evaporation of condensed Smoldering gas or pyrolysis oil is preferably by indirect heating with hot air.
- other coolants and heating agents it is also possible to use.
- preferred device with a carbonization gas generating Pyrolysis reactor and a gas converter connected downstream of it for converting the carbonization gas into cracked gas is according to the invention provided that between the pyrolysis reactor and the gas converter optionally with respect to the carbonization gas operable as a condenser or as a water heater Aggregate is arranged.
- the device has an optional cooling or Heatable container on which one Surrounds carbonization leading pipe.
- condensate container for the unit assigned to that with a heater for evaporation can be equipped with condensed carbonization gas.
- a unit 10 has a closed according to FIGS. 1 and 2 Container 12 with an inlet connector 14 and an outlet connector 16 for a cooling or flowing through the container 12 Heating medium.
- the container 12 encloses part of one Pyrolysis gas line 18 in which the carbonization gas or pyrolysis gas from a pyrolysis reactor not shown in the drawing to be led.
- the pyrolysis gas line 18 opens after the Emerges from the container 12 into a condensate container 20, the near the floor with a heating line 22 for evaporating Condensate or pyrolysis oil 24 is equipped.
- the condensate container 20 has in the area above the Condensate 24 receiving part a gas discharge line 26th on, via which from the pyrolysis gas line 18 into the condensate tank 20 transferred smoldering gas and possibly evaporated Condensate or pyrolysis oil 24 from the condensate container 20 emerges and one not shown in the drawing
- Commercially available gas converter for the generation of cracked gas supplied becomes.
- FIG. 1 shows the unit 10 in the “capacitor” operating state. That from the pyrolysis reactor via the pyrolysis gas line 18 emerging carbonization gas is through the container 12th flowing cooling water indirectly cooled, so that up the permanent gas adds practically the entire amount of carbonization gas Pyrolysis oil condensed and collected in the condensate container 20 becomes.
- the heater for the condensate tank 20 is not in operation, i.e. the heating line 22 is closed.
- FIG. 2 shows the unit 10 in the "instantaneous water heater" operating state. That from the pyrolysis reactor via the pyrolysis gas line 18 escaping carbonization gas is through the container 12 heating gas flowing through indirectly heated, creating a Condensation of the carbonization gas is prevented. In this operating state is the total amount of carbonization gas or pyrolysis gas available.
- the capacitor circuit 1 is selected.
- the flow heater circuit according to FIG. 2 is selected, possibly reinforced by the condensate heating.
- the choice of Circuit and the storage function of the condensate tank 20 bring about the desired decoupling of carbonization gas supply and carbonization consumption without handling the aromatic Pyrolysis oil is required. Only this decoupling makes the use of the environmentally friendly gas converter operational possible.
