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
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.
