Clean Air technology has a wide range. From cleaning filters, catalysts, washing technologies, to clean air knowledge and planning. The followings are some of the technologies and products:
Electrostatic precipitators with their countless areas of application remain the most economical system for the removal of dust from industrial gases. Low energy consumption, low cost of maintenance and spare parts and high life expectancy is the characteristic of this technology.
Evaporative coolers are used in the case of certain gas-cleaning processes, particularly in the cement industry. By injecting water, which is subsequently evaporated, the temperature of the waste gas is lowered to the necessary level for the operation of an electrostatic precipitator or other components. The gas volume and the specific resistance of the dust in the gas are reduced.
CATALYTIC GAS CLEANING
The process reduces toxic elements such as NOx, dioxin and furan and hydrocarbon and ammonia in order to comply with the toughest requirements worldwide and without producing residues that will require disposal.
FLUE GAS CLEANING
Multi-stage flue gas scrubbing
The main purpose is the safe separation of inorganic components and aerosols from the flue gas with quench, acid and neutral stages. The process is characterized by low energy input, durability and high operational reliability. This technology prevents the formation of aerosols thereby avoiding an elaborate and expensive additional stage. Additional systems, such as wet electrostatic precipitator or a ring-jet stage may be implemented on demand. The elimination of very fine particulates (PM10) is assured by using structured packing and formation by avoiding the use of spray nozzles for distribution of scrubbing liquid in the scrubber. This technology also uses flue gas scrubbers successfully for sewage sludge and for industrial waste incineration plants.
Dry and semi-dry processes
Dry and semi-dry processes are ideal when the unit is to be kept free from liquid effluents. This technology can eliminate fly ash, dust, acidic flue gas components, aerosols and PCDD/F.
