NANOSOLUTION
FOR GAS TURBINES
CARTRIDGE FILTER
CURRENT TECHNOLOGY
WHY USE NANOFIBRES?
Compact filters using the Nanofibres having all the best
factors together:
• Permeability (small pressure drop)
• The best filtering efficiency
• Very small thickness of the layer
• High porosity
• Low basis weight not increase filter media weight
• Small pore size
• High specific surface area
• Submicron particles capture
NEW TECHNOLOGY USING NANOFIBERSchematic of filtering material based on Nanosolution
SpunbondEngineeredpolymeric supportproviding thestiffness, mechanicalstrenght and pleatability for nanofiber layer
Active nanofibrous filtering layer with narrow pore size suitable for submicron filtration
Schematic of polymeric nanofiber layer on support layer
COMPARSION OF PRESENT AND NEW TECHNOLOGY
Filtering medium from Nanofibers magnified 600x – filtration class U17
Filtering medium from Nanofibers magnified 5000x
Filtration material – 100% synthetic spunbonded polyester – E12
Filtration material – cellulose / synthetic fiber paper E12
COMPARSION OF PRESENT AND NEW TECHNOLOGY
Current solution
Cartridge filters filtration class E 121. Static2. With pulse flush
Compact filter class E 12V – paneled filterZ – paneled filter
New Nanosolution
Cartridge filters filtrationclass ULPA 171. Static2. With pulse flush
-Triple layers- hydrophobic and oleophobic nanofibrous prefiltering layer + depth nanofibrous fiter + synthetic substrate - Lower pressure drop. - thanks to much greater active filteration surface, lower pressure drop, and much higher efficiency - MERV 15 and higher
NEW TECHNOLOGY USING NANOFIBRE
Filtration by Cartridge filters with class H12 – U17 and nanofibers
– Static filters with pulse flush
Pre – filter Layer removes large particulates, rejects moisture
High Efficiency Nanofibers layer removes submicron Dust, Water and Salts
Melt – blown offers high Strenght Backer, Provides Burst Strenght
BENEFITS OF NANOSOLUTION FOR FILTERING IN GAS TURBINES
1. Reduce Turbine Wear - (High filtration efficiency (for particulate > 0.3-0.5 micron) reduces fouling on the blade throughout) 2. Optimize Power Output - Eliminates power losses - Low fuel consumption - Low CO2 and NOx emissions3. Reduse salt corrosion 4. Low consumption of the cleaning pressure air for jet pulze cleaning filters
