Abstract
Mercury (Hg) and some other pollutants, from the group of volatile and semi-volatile toxic elements, have a character of global pollutants with strong negative impact on man and his environment. Consequently emission regulatory requirements are more and more stringent. For the industrial processes the restrictions will be introduced mainly through BAT reference parameters relevant for IPPC directive. Technological processes that are able to remove traces of mentioned pollutants are today in development and we witness very vivid research and development of the processes for removal of traces of mercury in thermal power plants. Even less is known about the behavior of other pollutants, e.g. As, Cd, Se and about their removal from process streams, especially together with mercury. Special problem are very demanding analytical procedures for determination of the elements and their chemical species, the later being of prime importance for the understanding and the control of the removal processes. The aim of the research is: 1. To determine the dynamic balance of the distribution of Hg and its species and of other pollutants (As, Cd, Se) in thermal processes of the thermal power plant, in the cement work and at (co)combustion of wastes. 2. To perform pilot test for the removal of pollutants from waste gases or from solids, intermediates from the industrial process, in which the pollutants have concentrated significantly. Pilot tests will be performed in pilot heterogeneous reactors, one in the system gas/solid (reactor and filter) and the other in the system gas/liquid/solid (simulating wet FGD). The aim is to produce equilibrium data on the distribution of pollutants between different phases (gas, adsorbents) at different operating conditions, the degrees of the saturation and the possibilities of the re-generation of saturated adsorbents. The final aim is to develop basic engineering data for the conceptual design and detailed design of the equipment for the processes for the removal of pollutants from the gaseous and solid streams in industrial processes and to develop the elements of the estimates of investment and operating costs.
Significance for science
The contribution to environmental sciences is expected by deepening the understanding of the chemistry of some toxic elements like Hg, Cd, As, in their different chemical forms through development of more accurately balances of the pollutants and thru development of dynamic models of pollutants distribution in some industrial processes. Using these tools and knowledge developed, the contribution to technical sciences are expected with further development of engineering solutions in high temperature industrial processes in TPPs, cement works and FCB incinerators of relevant wastes. The possibility of the use of the project results is very high and may be use in different ways. Knowledge developed will be used in the marketing of industrial processes in thermoenergetics, in cement production and waste incineration.. Target markets are smaller projects in China, SE Europe and Russia. Potential users of the knowledge are some Slovenian industrial organizations, before all TPP and cement works. The knowledge will be useful in the decision making process in waste incineration.
Significance for the country
The development of own technologies is increasing the competitiveness of the owners of the knowledge of industrial partners involved. The co-financier seeks to penetrate Chinese, E Europe including SE regions, Russian market, and also domestic market. More effective and economical technologies for the removal of pollutants, which all are the aims of this work, per se contribute to better environmental protection. This is important locally and in much broader sense, because some of the pollutants are global pollutants. Slovenia will with this project also insure more correct data about Hg emissions into the atmosphere, which have to be reported in line with EU directives. It has to be mentioned the compliance with EU Hg strategy recommendations (2005) that bind Slovenia to meet recommendations. In connection with this activity, the cooperation with the Ministry of the Environment and Spatial Planning has already been established.
