METHOD FOR THE ENVIRONMENTALLY SOUND DISPOSAL OF AIR/SOLVENT MIXTURES USING A FUEL CELL SYSTEM AND RECOVERY UNIT
The invention relates to a method for the environmentally sound disposal of air/solvent mixtures which are made of combustible gaseous vaporous or liquid waste products, using a fuel cell system for the recycling of the air/solvent mixtures while removing the environmentally compatible exhaust air developing in the fuel cell system, the waste heat that is produced and the electric power that is produced.

6 . A method for the environmentally sound disposal of air/solvent mixtures which comprises combustible gaseous, vaporous or liquid waste materials, with a fuel-cell plant for the utilization of the air/solvent mixtures, along with the discharge of the environmentally compatible exhaust air occurring in the fuel-cell plant and of the generated waste heat and of the generated electrical current, comprising delivering the air/solvent mixtures partially or completely to a recovery unit and converting the air/solvent mixture into a usable energy form, and partially or completely delivering the usable energy form to the fuel-cell plant for utilization, and consequently, during operation, the fuel-cell plant is automatically supplied partially or completely with fuel, and the fuel-cell plant operates on the basis of a molten carbonate fuel cell.
7 .
