Definitions

  • the invention relates to the emission of gases formed by the combustion of coal.
  • the invention relates in particular to a process for minimizing/eliminating the C02 and S02 emission emerging from the combustion of coal.
  • the coal is commonly used for the purpose of residential heating.
  • the lignite coals generally used have a high content of sulfur.
  • S02 emission released into the atmosphere along with the flue gases as a result of combustion causes substantial damages to the human health and natural environment.
  • the coals allocated to the residential sector are perceived as the grain coals with appropriate calorific value, which are washed and sieved, and generally no reduction is performed in the sulfur content of the original coal.
  • Acid rain is formed due to the coals with high sulfur content and it causes mixing between the drinking water and the groundwater.
  • the invention no. EP2227312B1 entitled “Method and device for reprocessing CO2-containing exhaust gases” relates to a method for reprocessing the CO 2 -containing exhaust gases in a multistage reduction process.
  • the CO 2 -containing exhaust gas is conducted in the counter stream to a solid mass stream of inert bulk material and organic material that can be thermally decomposed through a plurality of zones into a pressure equalization region and is thereby converted into pyrolysis gases.
  • the organic matter is thermally decomposed under reducing conditions into short-chained hydrocarbons, hydrogen and carbon monoxide to produce coke and residue.
  • the invention no. JP 9980057415 entitled “Method and system for processing the flue gas” relates to a method for subjecting the flue gases to treatment, said method including a step of heat recovery from the flue gas by means of a heat exchanger and also the heat recovery aiming to cool down the flue gas as well as a subsequent absorption step that involves bringing the flue gas into the gas- liquid contact with an absorbent-fluid from the absorption towers, thereby enabling the absorbent-fluid to absorb and eliminate SO2 present at least in the flue gas, said method being characterized in that there is conceived, prior to the step of heat recovery for instance, also a step of adding a powder, which is collectable at the stage of absorption, for example, for the purpose of spraying the coal ash into the flue gas.
  • an object of the invention is to minimize/eliminate the C0 2 and SO2 emission emerging from the combustion of coal.
  • Another object of the invention is to provide the soda generated as a significant input for the glass industry.
  • the invention is a process for minimizing/eliminating the C0 2 and S0 2 emission emerging from the combustion of coal characterized in that it comprises the process steps of - reducing the S0 2 emission by way of the treatment of the flue gas with the limestone (CaC0 3 )
  • the invention is a process for minimizing/eliminating the carbon dioxide (CO 2 ) and sulfur dioxide (SO 2 ) emission emerging from the combustion of coal.
  • the process according to the invention preferably comprises the process steps for the elimination of the emission of first SO 2 , then CO 2 and finally the residual SO 2 .
  • Sulfur dioxide is a colorless, odorous reactive gas that forms during the combustion of the sulfur-containing fuels such as the coal and fuel-oil and as a result of the metal melting processes and the other industrial processes. Its primary sources are the thermal power plants and the industrial boilers. The highest SO 2 concentrations are generally found in the vicinity of the big scale industrial sources. For example, the limestone at a ratio of 1/15 - 1/20 by weight (depending on the percentage of sulfur) is used as an additive for Soma coal. (For example, this should not exceed 2% according to Turkish Standards, whereas the value is 0,9% for Europe and around 1 ,2% for Soma.)
  • C0 2 Emission By means of a method for guiding the carbon dioxide (C0 2 ) emitted with the flue gas and spraying on a fluidized bed, the C0 2 emission is eliminated and the soda (NaHC0 3 ) is formed as a result of the reaction of the carbon dioxide (C0 2 ) with the caustic soda (NaOH). The mixture of water and soda thus formed is dried by means of known methods in order to allow for the use of soda. Soda (NaHCO 3 ) is an important raw material for the glass industry.
  • the carbon content in the commercial coal is at least around 70%. If this value is taken to be 80%, it means that 1 kg coal contains 0,8 kg carbon. During the combustion, the carbon combines with oxygen to form CO 2 . For 0,8 kg of carbon, 2,93 kg of CO 2 is released. In the factories generating energy from the coal, this value is used as the CO 2 emission factor. CO 2 gas emission per unit electricity generation is 1 ,47 kg/kWh.
