ABSTRACT

Emissions permitted limits are set by environmental legislations; these limits are very similar in most countries of the world. Efficiency in treatment of air pollutants should meet these established limits. There are different industrial sources of pollutant emissions such as industrial flue gases stacks. The typical volume of a flue gas produced from municipal solid waste incinerators is between 4,000 and 6,000 m3 per ton of waste. The pollutant emissions that are produced by a combustion plant take the form of particulates, gases such as carbon oxides (COx), nitrogen oxides (NOx), water vapor (H2O), sulfur oxides (SOx), hydrogen chloride (HCl), hydrogen fluoride (HF) and other hydrocarbons such as polycyclic aromatic hydrocarbons. The selection of the appropriate gas clean-up system depends on the type and quantity of waste in the gas effluent and the emission limits to atmosphere or the required treatment efficiency. Industrial control of discharges of atmospheric pollutants should be arranged before and after the production process in order to minimize emissions of pollutants.
