Flue gas treatment multi-criteria analysis

Energy is the main factor effecting national economies of countries, therefore it is in everyone's best interest to improve energy efficiency. One way to do that is by developing and implementing heat recovery from industrial processes, rather than creating waste heat in industry. There are different technologies available for heat recovery, for example, heat pumps, heat exchangers, boilers, etc. [1]. The choice of a certain technology is dependent on the heat source. In this paper, focus is brought to heat recovery from power industry, more precisely - heating system, with a condenser. An evaluation of direct contact flue gas condenser (KE) from emission reduction perspective was performed. The best KE alternative has been found using multi-criteria analysis method, based on analysis of 14 chosen quantitative and qualitative criteria.
