GAS CLEANING SYSTEMS "HEKAS" HIGH EFFICIENCY
CATALYTIC SYSTEMS – “ZERO SMOKE" (Ringelmann Opacity Scale=0 (Zero)) BUILT WITH EXCLUSIVE TECNOLOGY OF “INCOL INCINERATION” OF THE UNITED KINGDOM
RStrict standards of emissions and severe Environmental Standards demand the use after the post-combustion of Equipment for Treatment and Gases Cleaning emitted to the atmosphere.
The strictest Environmental current Legislation, for example of the UE, the British Standard and of Germany and Belgium, demand Systems of High Efficiency better than Cyclones, Conventional Systems of Dry Via with Bag Filters, Systems of Wet Via, SCR, Electrostatic Precipitants, DENOx, etc..
This Equipment, allows reducing emissions limits up to lower values compared with conventional ones, as shown below:
- NOx more than 95%
- SO2 more than 85%
- Dioxins and Furans more than 99%
- Particulate Material lower than 2mg/Nm3
- All of them are measured to 11% of Free Oxygen
GAS CLEANING SYSTEMS, WET WAY – 9 (NINE) PROCESS PHASES.
Strict standards of emissions and severe environmental norms demand the use after the post-combustion of equipment for Treatment and Gases Cleaning emitted to the atmosphere. Integrated by Scrubbers Towers of high efficiency, used for the removal of Particulate Material, Acid Gases and Heavy Metals. Also used to inhibit and avoid the generation of Dioxins and Furans, in order to keep them under specified limits. Using this tested technology, with automatic controls, it is possible fulfill with the limits of gaseous effluents established by some legislations, which are not much restrictive..
GAS CLEANING SYSTEMS, WET WAY – 12 (TWELVE) PROCESS PHASES.
Strict standards of emissions and severe environmental norms demand the use after the post-combustion of equipment for Treatment and Gases Cleaning emitted to the atmosphere. Integrated by high efficiency Scrubbers Towers, used for the removal of Particulate Material, Acid Gases, contaminant Heavy Metals. Also used to inhibit and avoid the generation of Dioxins and Furans, in order to keep them under specified limits. Using this tested technology, with automatic controls, it is possible fulfill with the limits of gaseous effluents established by some legislations, which are not much restrictive.
GAS CLEANING SYSTEMS, DRY WAY
It is about a Gases Cleaning System in Dry Phase, with Cooling Chamber and Energy Recuperation. It has a graduated entrance of fresh air, so that it could fit out its Temperature with the specified requirements that is in case of a Boiler or a Heat Exchanger. It is added a dispenser Equipment for neutralizer elements, which are thinly pulverized, such as the alkaline element for the acid gases absorption and the active carbon that works on dioxins and furans that might be present in circulate gases. The hopper for its storage and the Dispenser of Flow are incorporated to the System to fulfill its commitment. The Filter Equipment hold the Particle Material, the pulverized neutralizer products previously added, for the retention of the compounds present in gases such as the halogenated and heavy metals. An induced draft fan built in a special material is used to overcome drop of the system pressure. An emergency in by-pass chimney is installed, in order to protect the Cleaning System and the Fan mentioned before in case of luck of electric energy or in case of pressure of suction fail. The system is fulfilled by a chimney that leads gases to exterior.
ENERGY RECUPERATION
Boiler may be added in order to achieve Heat Recuperation, so that use properly the enthalpy typical in gases and generate Saturated Steam in quantities related to the Model of Furnace or hot water, according to the case.
MERCURY ABATEMENT EQUIPMENT
THIS SYSTEMS FOR TREATMENT AND CLEANING GASES USING CHIMNEY, OBEY EVERY REGULATION IN THE “U.S.E.P.A.”, IN THE “BRITISH STANDARD”, IN THE “27BPm. SchV” OF GERMANY, PORTUGAL, AUSTRIA AND COUNTRIES OF THE EAST EUROPE.
Gases of Post-Combustion Chambers are treated, as follows:
- Event of Abrupt Cooling of Gases from 900º up to 200º
- Neutralization of acid gases with components like HCI, SO2, HF, etc.
- Removal of Particle Material from Heavy Metals and Mercury (Hg)
