Abstract:
A method for the control of nitrogen oxides content in the combustion fumes of a thermal power plant is disclosed; the method comprises the on-site production of ammonia by the steps of: electrolysis of water as a source of hydrogen; separation of air as a source of nitrogen, formation of a make-up gas and synthesis of ammonia in a suitable synthesis loop; said on-site produced ammonia, or a solution thereof, is used for a process of reduction of nitrogen oxides in the combustion fumes.

Claim (Index 7):
A method for modification of an installation comprising a unit for reduction of nitrogen oxides from a combustion flue gas (G), wherein:\n an on-site ammonia plant, for the generation of ammonia and for use in said reduction unit, is added to said installation, said ammonia plant comprising at least: a water electrolysis section (WE) for production of a hydrogen current from water and electric energy; an air separation unit for production of a nitrogen current from air; means to form an ammonia make up gas by using said hydrogen current and nitrogen current, and an ammonia synthesis section (SL); wherein said installation is a power plant for the production of electric energy and the production rate of ammonia is regulated according to the load of said power plant and/or according to the demand of electric energy, such that the production of ammonia is increased during electricity off-peak hours when the demand of electricity is low, and is reduced or stopped, thus maximizing the net output of said plant, during electricity peak hours when the demand of electric energy is higher.
