New Ion Exchange Fibers VION
LTD Lirsot offers VION fibers and textile materials based on these fibers which are successfully used for the purification of air and gas fluids from a number of toxic and aggressive gases (SO3, SO2, HF, HCl, Cl2, H2S, NH3), and aerosols (acid mists, salt aerosols). VION fibers are also used for cleaning aqueous media.
Filtering systems using VION fibers ensure high stability of purification, rational equipment for sorption processes, reduction of equipment size and material lowering of energy consumption. The use of VION fibers is especially advantageous in processes where concentration of sorbed substances is low, for the recovery of especially valuable or very toxic substances.
In comparison with granular ionites, VION fibers
feature a high sorption rate, especially at the initial stages of the process thus ensuring sorption without additional energy consumption. 50 % saturation of the fibers is achieved in 5-10 min, whereas it takes at least one hour with granular ionites
feature a very large surface which ensures:
- lowering of resistance of the filtering layer;
- enhancement of stability of purification;
- simpler design of filters;
- lower energy and water consumption
feature a three-dimensional chemical structure; high hydrolytic stability so that their reuse for sorption processes is possible
The fibers retain their static capacity and mechanical properties after 100 sorption/ regeneration cycles.
CHEMISORPTIVE FIBER "VION AN-3" and the POLYAMPHOLYTE NON-WOVEN LINEN.
Are used to purify the gas-air and liquid environments from: SO2, HF, HCI, H2S
Functional groups: - COONa (Na - form), - NH -NH2
are used to purify the gas-air environment from the toxic and aggressive gases: SO2, SO3, NH3;
trap toxic or valuable gaseous substances and liquid aerosols
purify and after purify waste liquors with a concentration of noxious or valuable substances below 40 mg/l. The use of other trapping methods with such concentration is not economically effective
purify air in ventilation systems with a throughput capacity of up to 50,000 m3/h
used for the manufacture of protective garment to protect against splashes and drops of aggressive liquids. The garment is air- and moisture-proof and is impermeable for noxious substances
used in respirators for personal protection of respiratory organs. Resistance to respiration is 4-5 times as low and the mass of the filtering material is 5-10 times as low
used for the analysis of gaseous mixtures. Accuracy of the analysis is enhanced and time is cut down. Efficiency of determination of ammonia in gases at high moisture content is rather high. VION KN-1 fiber can sorb not only gaseous ammonia, but also its mist, whereas liquid absorbents such as sulfuric acid solution can only sorb gaseous ammonia.
The list of the above fields does not exhaust all applications VION fibers.
