Definitions

  • the invention relates to a method for treating water-containing condensate from the cooling of the raw gas of the gasification of solid fuels with gasifying agents containing oxygen, water vapor and carbon dioxide under a pressure of 5 to 100 bar, the fuels forming a fixed bed which slowly moves down and under which the incombustible mineral components of the fuel are extracted as solid ash or liquid slag.
  • the relaxation steam becomes one Combustion chamber fed and burned at temperatures above 800 ° C. Part of the liquid phase must be removed from the process and worked up, because otherwise the concentration of the impurities in the gas or in the condensate would increase to impermissible values. However, the processing and cleaning of liquids causes considerable costs.
  • the invention has for its object to eliminate the portion of the condensate that can not be returned to the gasification or reused in the treatment of the raw gas in a simple and economical manner.
  • this is done according to the invention in that the condensate is at least partially burned in a fluidized bed combustion at temperatures in the range from about 750 to 1000 ° C. and the combustion gas containing water vapor is passed from the combustion into the gasification. There is no need to clean a condensate component and the combustion gas serves as a gasifying agent in the gasification.
  • a further development of the invention consists in that the condensate obtained during the cooling of the raw gas is at least partially freed of dust and tar in a separator before the condensate is fed to the fluidized bed combustion. Dust and tar are returned to the gasification in a known manner.
  • Part of the combustion gas is expediently returned to the fluidized bed combustion, the gas serving as the fluidization medium.
  • the process also offers the advantageous possibility of sulfur compounds and from the raw gas after cooling Remove carbon dioxide and give up these substances of fluidized bed combustion together with calcium compounds.
  • the CO2 is retained in the gasification process and reduces coal consumption.
  • the sulfur compounds, in particular H2S, are converted to SO2 in the fluidized bed combustion and combine with the calcium compounds, in particular limestone or milk of lime, to form calcium sulfate. Calcium sulfate is then drawn off with the combustion axis and can be deposited without any problems.
  • An advantageous embodiment of the method consists in operating the fluidized bed combustion at a pressure which is at least 2 bar higher than the pressure of the gasification. As a result, the combustion gas can be introduced into the gasification without additional compression.
  • the classic fluidized bed or, preferably, the circulating fluidized bed can be used, for which details are described in German specification 25 39 546 and the corresponding US Pat. No. 4,165,717.
  • the speeds of the fluidizing gas are considerably higher than in the classic fluidized bed, so that large amounts of solids are continuously discharged from the fluidized bed reactor, separated from the gas and fed back into the fluidized bed reactor.
  • the gasification 1 is fed granular coal with a grain area of about 3 to 60 mm through the line 2.
  • lock devices are not shown in the drawing.
  • Gasifying agents come from line 3, they consist of a combustion gas to which oxygen is added through line 4.
  • the incombustible residue of the gasification, which is solid ash or liquid slag, is discharged in line 5.
  • the raw gas of the gasification passes in line 6 to a washer cooler 7, in which water or condensate consisting predominantly of water is fed through line 8.
  • a washer cooler 7 in which water or condensate consisting predominantly of water is fed through line 8.
  • further cooling takes place, so that the raw gas in line 11 is drawn off at temperatures in the range from 120 to 180 ° C. and in the bottom of waste heat boiler 10 a condensate is also obtained at temperatures of from 120 to 180 ° C.
  • This condensate is fed to a separator 13 in line 12.
  • the pressure in the separator 13 is only about 1 to 5 bar lower than in the gasification 1.
  • the gravitational separation of various components of the condensate takes place in a manner known per se.
  • a heavy phase which is rich in dust and tar, is drawn off in line 14, it being advisable to also feed this phase to gasification 1.
  • a water-rich phase which is usually referred to as gas water, is drawn off in the line 15 and, under the action of the pump 16, is given up to a fluidized bed combustion 17. If necessary, make-up water is introduced in line 9.
  • the fluidized bed combustion 17 is also supplied with an exhaust gas from the line 18, which is sucked in by the fan 19 from a gas cleaning device 20.
  • the raw gas from the line 11 is treated, sulfur compounds, in particular H2S, and also partly CO2 being removed by known processes. CO2 and these sulfur compounds are contained in the exhaust gas of line 18.
  • the cleaned gas which now mainly consists of hydrogen and carbon monoxide, is available for further use in line 21.
  • the fluidized bed combustion 17 is supplied with fine coal with a grain size of up to 10 mm through line 22 and ground limestone, dolomite or milk of lime through line 23 as fuel. These calcium compounds are converted in the combustion 17 at the prevailing temperatures of 750 to 1000 ° C and preferably 800 to 900 ° C to CaO, which binds the SO2 formed from the sulfur compounds as calcium sulfate.
  • the combustion 17 uses a partial flow of the combustion gases which is returned in line 25 and to which oxygen, air or also oxygen-enriched air is mixed in line 26.
  • this gas is introduced through line 34 Water sprayed in, which can also be condensate or gas water.
  • the combustion gas enriched with water vapor is then partly returned to the combustion 17 via the blower 35 and the line 25 in the manner already described, the remaining combustion gas is fed to the gasification 1 in line 3.
  • the gasification is given 1 1000 kg of coal (free of water and ash).
  • the coal which has a grain size range of 5 to 40 mm, contains 51 kg moisture, 126 kg ash and 21 kg sulfur.
  • Combustion gas which consists of the following gas components, is brought in through line 3 as the gasifying agent: CO2 107 Nm3 O2 7 Nm3 N2 2 Nm3 and that contains 323 kg of water vapor.
  • the temperature of the gas is 400 ° C. 477 Nm3 of oxygen from line 4 are mixed into the combustion gas.
  • the pressure in gasification 1 is 30 bar and in combustion 17 is 32 bar.
