DEMISTER Use :
1: Knockout drums and separators – save on capital costs by decreasing vessel size-recover costly fatty acids from stream-reduce compressor maintenance by preventing scale build-up.
2: Absorbers – reduce overhead losses of glycols in dehydrators to no more than 0.1 gal/MMSCF natural gas-cut losses of absorption oil and amines in CO2 systems.
3: Scrubbers – reduce chemical discharges from Kraft mill smelt dissolver tank to less than 0.11 kg/dry ton (0.25 lb/dry ton) of pulp-improve scrubber efficiency by removing particulates carried in entrained liquids.
4: Distillation columns – improve product purities and increase throughput capacities for petrochemicals, organic intermediates, fine chemicals.
5: Evaporators – prevent carryover loss of valuable products, keep condensate TDS <10 ppm for highest quality boiler feed water-clean up vacuum ejector stream discharge-lower maintenance in vapor re-compression systems.
6: High pressure steam systems – provide dry steam- cut TDS to <10 ppb in condensate-eliminate build-up on turbine blades.
7: Refinery towers – increase throughput capacity-take deeper cuts for greater product yields – prolong catalyst life in downstream cracking and reforming units by reducing carbon and metals in side draws-use lower grade crudes.
DEMISTER Material Polytetrafluoroethylene has a very high chemical resistance, such as in concentrated sulfuric acid, nitric acid, hydrochloric acid, even boiling in aqua regia, its weight and performance have no change, and it is almost insoluble in most solvents, only slightly soluble in paraffins (about 0.1g / 100g) above 300 ℃. Polytetrafluoroethylene is non hygroscopic, non combustible, extremely stable to oxygen and ultraviolet, so it has excellent weather resistance. It should be noted that polytetrafluoroethylene can not withstand strong reduction atmosphere melting of alkali metals, ammonia alkali solution (alkali metals dissolved in liquid ammonia), some fluorides (such as TFA), naphthalene sodium salt, etc. can rapidly corrode polytetrafluoroethylene products. The dielectric constant and loss of polytetrafluoroethylene in a wide frequency range are very low, and the breakdown voltage, volume resistivity and arc resistance are high.
The radiation resistance of polytetrafluoroethylene is poor. It is degraded by high energy radiation, and the electrical and mechanical properties of the polymer are obviously reduced. Polytetrafluoroethylene is produced by free radical polymerization of tetrafluoroethylene. Industrial polymerization is carried out by stirring in the presence of a large amount of water to disperse the reaction heat and facilitate temperature control. The polymerization is generally carried out at 40-80 ℃, 3-26 kgf / cm. Inorganic persulfate and organic peroxides can be used as initiators, and redox system can also be used as initiators. The exothermic energy per mole of tetrafluoroethylene is 171.38kj. Dispersion polymerization requires the addition of perfluorinated surfactants, such as perfluorooctanoic acid or its salts.
