1 ABSTRACT This diploma thesis deals with comprehensive analysis of emission limits which is one of the most important instruments of environment protection. The purpose of this diploma thesis is description and analysis of emission limits in protection of fundamental environmental compartments and in some cases also demonstration of its functioning on practical examples. The text of this diploma thesis is divided into six chapters. Firstly, this thesis provides a general characteristic of fundamental concepts, which creates a basis for all following parts of this diploma thesis. Further follows three chapters devoted to in detail description and analysis of emission limits in certain environmental compartment, whereas firstly there is always introduced its past and present progress. Further follows international, EU and national sources of law with evaluation. These two parts are followed by the third part which deals with in detail analysis of specifics and process of determination of emission limits values and eventually monitoring and evaluation of pollutants levels released by polluter. In conclusion of all these three chapters there is comprehensively summarized partial problematics and author's considerations about possible shortcomings in areas of achievable improvement. Last sixth chapter is...
Technology to remove sulfur oxides (NOx) from flue gases for large combustion plants
Hrubý, Radomír ; Bojanovský, Jiří (referee) ; Jecha, David (advisor)
In the specified large combustion plant, fuel with a large content of sulfur is burned. The current desulfurisation method is not able to meet the new emission limits, therefore it is necessary to design an adequate desulphurisation method. The theoretical part of this diploma thesis contains a description of the legislation related to emission limits for large combustion plants and an analysis of individual technological methods of desulphurization together with a description of the relevant sorbents. The practical part of the work contains a design of dry conditioned sorption with the using of a calcium-based sorbent. The basic technological and structural design is designed together with the spatial solution and dispositional solution of the whole technology.
Technology to remove nitrogen oxides (NOx) from flue gases for large combustion plants
Kučera, Jan ; Brummer, Vladimír (referee) ; Jecha, David (advisor)
This diploma thesis deals with selected abatement techniques of nitrogen oxides (NOx) developed for large combustion plants. The first part describes selected NOx, their properties and explains the formation during combustion. Furthermore, there is an analysis of current legal legislation regulating the issue of emission limits. The third part presents selected primary and secondary measures that are widely used. The emphasis is placed on the description of selective catalytic (SCR) and non-catalytic reduction (SNCR). Finally, the basic design of these technologies for model combustion equipment is performed. The consumption of reducing medium and the volume of the catalyst for the mentioned techniques are calculated here. The estimate of selected operating and investment costs is a part of the basic scheme.

Emission measurement and analysis of air pollution stationary sources
Grössl, Ladislav ; Vach, Marek (advisor) ; Najnarová, Eva (referee)
This bachelor thesis deals with measuring of stacionary sources. In the nineties years of twenty century in Czech republic there was the highest amount of emission of major pollutants. Thanks to the new law and standards the actual level of emission was reduced. By inherent measuring stationary source, which burns natural gas in Kouřim, was found, that amount of emissions do not exceed permitted limits. Furthermore were this measurements compared with a source, which burns light fuel oil.
Catalytic oxidation of VOC on commercially available catalysts
Osička, Tomáš ; Jecha, David (referee) ; Brummer, Vladimír (advisor)
The main topic of this thesis is a catalytic oxidation which belongs to a group of modern technologies for removing emission of CO and VOC from waste air. In the introduction of this thesis, the basic concepts are defined. Further the legislative requirements associated with VOC emissions, emission limits and conditions are summarized. Described destructive and non-destructive methods for removing VOCs from waste gases are also briefly described. Increased attention is paid to the catalytic oxidation as the main theme of the thesis. It was searched for industrial applications where the catalytic oxidation is used. Another chapter is devoted to the theoretical analysis of kinetics of catalytic oxidation reactions. Firstly, the basic types of reactors are described and also material balance and reaction rate for the isothermal and adiabatic reactor. In the experimental part results of performed kinetic measurements on a pilot unit for catalytic commonly used organic solvents (VOCs) using commercially available catalysts were summarized. Pre-exponential factors and activation energies for sprinkling catalysts EnviCat VOC-5565 and EnviCat 55068 for substances ethanol, toluene and acetone were determined. "Light-off" curves for these substances and methane were measured and on sprinkled catalyst EnviCat 55068 and on monolithic catalyst Purelyst PH-304.
