Brass and bronze metal powders enabled high-temperature porous filters for petrochemical processing, replacing failed polymer alternatives.
A petrochemical plant was using polymer-based filter elements for high-temperature catalyst recovery and gas stream filtration. The polymer elements failed catastrophically when process temperatures exceeded 200°C, causing:
LSBT supplied a combination of brass and bronze powders for manufacturing sintered porous metal filter elements with controlled permeability:
BRASS 200 Powder — CuZn 20%, irregular atomized. Engineered particle size for sintered porous filter applications with controlled permeability.
BRONZE UDX Fine Bronze — Cu89/Sn11, -45μm (-325 mesh). Water atomized irregular, 2.8-3.5 g/cm³. Ideal for fine-pore sintered filters.
Nickel 99.97% Pure — Gas atomized spherical, 4.5-5.8 g/cm³. Corrosion-resistant addition for harsh chemical environments.
The sintered brass/bronze filter elements operated continuously at 500-600°C with a filtration rating of 0.5 microns. Service life extended from 2-3 weeks (polymer) to over 6 months. The ability to operate at optimal process temperatures improved catalyst recovery efficiency by 12%.
