Pure PTFE mesh pad demister with mounting frame custom segment plan
PTFE mesh pad demister material:
The friction coefficient of polytetrafluoroethylene (PTFE) is only 1 / 5 of that of polyethylene, which is an important feature of perfluorocarbon surface. Because of the low intermolecular force between fluorine and carbon chain, polytetrafluoroethylene has no viscosity. Polytetrafluoroethylene has excellent mechanical properties in a wide range of temperature from - 196 ℃ to 260 ℃. One of the characteristics of perfluorocarbon polymer is that it is not brittle at low temperature. The density of PTFE is 2.14-2.20g/cm, almost no water absorption, and the equilibrium water absorption is less than 0.01%. Polytetrafluoroethylene (PTFE) is a typical soft and weak polymer. The interaction between macromolecules is small, the rigidity, hardness and strength are small, and it will deform under the long-term stress.
PTFE mesh pad demister application:
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.
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.
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.
Distillation columns – improve product purities and increase throughput capacities for petrochemicals, organic intermediates, fine chemicals.
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.
High pressure steam systems – provide dry steam- cut TDS to <10 ppb in condensate-eliminate build-up on turbine blades.
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.
