Definitions

  • the present invention relates to a method for variable power gasification of products such as biomass and organic byproducts (plants, animals, domestic refuse, sewage sludges), it being understood that:
  • French patent FR No. 78 31356 describes a gas producer with a fixed bed comprising a horizontal treatment chamber in which the materials to be treated are introduced through one of the ends, and then are driven inside the chamber by a driving device up to a discharge aperture formed in the lower portion of the wall of the chamber at its second end. Between both ends of the chamber, the wall comprises two outlets spaced apart from each other, i.e.:
  • the first outlet is connected through a recycling circuit to an injection nozzle, located below a pre-heated air injector, so that the hot gases produced by the reaction of the recycled gases and of the pre-heated air are injected towards the first end of the chamber, at a level corresponding to that of the base of the slope formed in front of the material contained in the chamber. Consequently, the material particles which are the closest to the aperture are attacked by the hottest gases (about 1,200° C.) so that the ashes are rejected after the carbon has been totally gasified.
  • This solution notably has the advantage of reducing the drying and pyrolysis times by the forced hot gas circulation generated by the recycling. Further, the use of hot gases is optimized in order to obtain complete and rapid gasification.
  • the drawback of the solution as described in this document consists in that it does not comprise a self-adaptive structure capable of optimizing the gasification process according to the flow rate of the treated material or, conversely, according to the required power output, and this for variable flow rates or powers in relatively wide ranges.
  • Patent FR No. 80 16854 proposes improving the treatment method as described earlier by having a heated-up gas flow resulting from recycling pass through the material to be treated, no longer axially as earlier, but transversely relatively to the longitudinal direction of progression of the materials during the treatment in the chamber.
  • the treatment chamber comprises a succession of treatment modules, each comprising its own recycling, air admission and combustible gas extraction means. This is therefore a relatively expensive solution.
  • the goal at which this solution is aimed is obtaining an optimization of the flow characteristics of the gases through the crossed material layer and not adapting the operation of the treatment chamber according to the material flow rate and/or the required power output, because of the presence of several oxidation zones and of a single gasification zone.
  • the object of patent application FR 2 263 290 is a method and installation for treating bituminous shales and asphaltic limestones by pyrogenation.
  • This method mainly consists in a treatment in a vertical gas producing oven of rocks containing exploitable organic material and notably bituminous shales, in which these rocks are first submitted to a pyrogenation reaction and then to a gasification reaction.
  • This method is characterized in that:
  • the object of the invention is a gasification method with which the operation of the treatment chamber may notably be adapted according to the nature of the material and/or to the required power output, by means of functional adaptation of the treatment chamber and this without any significant physical modifications, and without increasing significantly the cost of the installation.
  • This method involves an installation which comprises a reactor comprising a treatment chamber in which the materials to be treated successively pass through a drying/pyrolysis zone of variable dimensions in which pyrolysis gas extraction is carried out, and then through a gasification zone of variable dimensions in which synthesis gas extraction is carried out, the pyrolysis gas extracted in the drying/pyrolysis zone being injected into the airspace of the reactor with an oxidizing gas, so as to generate an exothermic oxidation reaction providing the energy required for pyrolysis and gasification reactions.
  • the dimensions and/or the position of the drying/pyrolysis and gasification zones are adjusted according to the amounts of material to be treated introduced into the treatment chamber, to their nature, notably on the their grain size and to their hygrometry level and/or to the power output needs, and in that the combustible material substantially circulates horizontally by means of a pusher or the like allowing the combustible material to advance from upstream to downstream from the reactor.
  • the treatment chamber may comprise between the drying/pyrolysis zone and the gasification zone, a mixed zone in which either extraction of pyrolysis gas or extraction of synthesis gas may be carried out, the type of extraction carried out in this zone being determined according to the amounts of materials introduced into the treatment chamber, to the nature of this material and/or to the power output needs.
  • At least one of the aforesaid zones may comprise several successive controllable gas extraction areas, the variation of the dimensions and/or of the position of said zones being obtained by partial or total deactivation of said areas.
  • the invention also relates to a gasification installation allowing the application of the method defined earlier, this installation comprising a fixed a bed reactor which comprises a treatment chamber comprising a sole on which the bed of combustible material substantially circulates horizontally, said bed being divided into at least three zones, i.e.:
  • the zone of the treatment chamber corresponding to this extraction means or to this circuit is made at least partly inactive. It therefore becomes possible to distribute the active and inactive zones of the treatment chamber according to the nature of the material to be treated, to the amounts of material to be treated and/or to the desired power output.
  • the presence of the multifunctional intermediate zone in which the extraction means may be connected to the pyrolysis gas extraction circuit or to the synthesis gas extraction circuit notably allows axial displacement of the location where the separation is carried out, between the pyrolysis gas extraction zone and the synthesis gas extraction zone.
  • this system comprises at least one piece of equipment notably having the purpose:
  • This treatment equipment (tar condenser) is preferably designed so as to carry out wet treatment of the gas under ambient conditions, with a cooling step which is performed on a gas-water tube exchanger with which the substantial heat of the synthesis gas may be recovered and the tars may be separated from the gas.
  • This three-fluid exchanger may comprise a plurality of vertical tubes in which the synthesis gas circulates as well as means with which a falling film formed by circulation of oil may be generated in the tubes. This falling film has the effect of trapping the dusts and tars thereby preventing fouling of the tubes. By cyclically drawing off oil, it is possible to maintain its quality by deconcentrating it by adding new fluid.
  • FIG. 1 is a schematic illustration of a fixed bed gasification installation
  • FIG. 2 is an elevational view with partial cut-aways of a three-fluid exchanger-condenser device which may be used in the installation illustrated in FIG. 1 .
  • the gasification installation involves a fixed bed reactor 1 of tubular shape, for example with a circular or polygonal section, comprising a treatment chamber 8 .
  • This reactor 1 and this chamber 8 are connected at one of their ends (upstream) to a combustible material supply system 2 and comprise at the other downstream end a system 3 for extracting ashes.
  • the supply system 2 comprises a worm-screw conveyor 4 or any equivalent device located in the storage area 5 of the combustible material.
  • This conveyor 4 delivers onto a belt conveyor 6 which feeds a vertical supply air-lock 7 which opens out inside the treatment chamber 8 of the reactor 1 at right angles to a discharge area 9 of the bed poured into said chamber 8 .
  • the material delivered by the air-lock 7 onto this discharge area 9 is pushed back towards the inside of the chamber 8 by a pusher 10 with an alternating movement.
  • the sole of the treatment chamber 8 is formed by a succession of gas extraction areas on which the bed of combustible material may circulate under the driving effect of the pusher 10 .
  • This sole comprises one or more grids 11 - 15 covering portions under each of which a hopper T 1 -T 5 is positioned, the lower portion of which is provided with an obturator or register 16 - 20 intended for discharging fine material particles passing through the grid(s) 11 - 15 .
  • the sole successively comprises two pyrolysis gas extraction areas (grids 11 and 12 ), two mixed or polyvalent extraction areas (grids 13 and 14 ) and an area for extracting synthesis gases (grid 15 ).
  • the hoppers T 1 -T 4 are each connected to the suction inlet of a pyrolysis gas extraction circuit 21 and of a turbine 23 , via suction conduits 24 , 25 , 26 , 27 , equipped with valves 28 , 29 , 30 , 31 .
  • the hoppers T 3 , T 4 , T 5 are connected to the suction inlet of a synthesis gas extraction circuit 37 via suction conduits 31 ′, 32 , 33 equipped with valves 34 , 35 , 36 .
  • the extraction circuit 37 successively comprises the primary of a gas/air heat exchanger 38 and, optionally, a scrubber system for the gases 39 . It is connected to the suction inlet of a turbine 40 , the outlet of which is for example connected to a synthesis gas distribution network.
  • the downstream end of the treatment chamber 8 is provided with a well 41 for extracting ashes, the lower end of which is immersed in water 42 contained in a tank 43 for recovering ashes, which extends under the treatment chamber 8 .
  • the obturators (or registers) 16 - 20 are connected to sleeves M which are immersed in the water of the tank 43 .
  • the particles of ashes or of combustible materials collected by the tank are carried away by a conveyor 44 and poured at a height above the water level of the tank 43 into an area 45 for storing ashes and residues.
  • the turbine 23 of the pyrolysis gas extraction circuit is connected through its outlet to a burner 50 which injects into the airspace of the treatment chamber 8 a gas mixture comprising the pyrolysis gas as well as an oxidizer which may consist in preheated air from a circuit 46 passing through the secondary of the heat exchanger 38 and from a turbine 47 or in oxygen from a distribution circuit 48 controlled by a valve 49 .
  • the starting of the installation is moreover ensured by means of a burner B using natural gas from a circuit C controlled by a solenoid valve E. This burner B is maintained in operation until the reaction temperature is reached.
  • the gases are extracted at a temperature of the order of 500° C.-700° C.
  • a processor P which controls the rate of supply of the airlock with combustible material, the condition of the registers 16 - 19 and of the valves 28 - 31 and 34 - 36 , the speed of rotation of the turbines 23 , 40 , 47 , the speed of rotation of the motor driving the conveyor 44 which ensures extraction of the ashes and of the residues.
  • This processor is moreover connected to detectors (notably a temperature detector DT and a pressure detector DP) with which the different parameters of the installation may be measured in order to provide the controls and safety measures.
  • detectors notably a temperature detector DT and a pressure detector DP
  • adjustable parameters may directly contribute to the performance of the installation, i.e., notably:
  • the gasification installation has the following advantages:
  • the gas scrubbing system 39 may consist of a tar condenser comprising a vertical tubular column CT closed at both of its ends and the internal volume of which comprises from top to bottom:
  • the synthesis gas forms the fluid to be treated.
  • Water is used as a main heat transfer fluid which absorbs part of the heat released by the gas.
  • the oil which is used for capturing the tars also plays the role of a secondary transfer fluid ensuring preheating of the water.
  • the gas which enters the admission chamber 51 at a relatively high temperature flows through the exchanger 53 from top to bottom inside the tube 56 while cooling upon contacting the latter.
  • the water After having been preheated in the coil 62 , the water passes through the exchanger 53 from bottom to top while heating up upon contacting the tubes 56 .
  • the oil which is supplied in the admission chamber 51 enters the tubes 56 by overflow and forms films falling along the inner walls of the tubes 56 before finally reaching the reserve 61 .
  • the substantial heat of the gas is transferred to the water by passing through oil films and the walls of the tubes 56 .
  • the tars present in the gas are captured by the oil films during the direct tar/oil contact.
  • the oil present in the reserve 61 may be regularly drawn off by means of a purge pipe 65 .
