Scrubber & Cyclone Linings

The wear and corrosion-resistant properties of ALTRON™ and NITRON™ make it a perfect candidate for an engineered shape or wear lining in your Fluid Catalytic Cracking Units. With ASTM C-704 abrasion numbers approaching 1.50 cc loss, ALTRON can provide 2-3x better and longer wear resistance over conventional hexmesh castable, which makes it perfectly suited for the severe environment within the FCCU.

Products like scrubber nozzles, third stage separators, venturi, cyclone, dipleg, elbow, piping, and dustbowl linings can all be made into precast single piece shapes or engineered and interlocking tile arrangements.

Reliability and maintenance engineers worldwide rely on Blasch high-performance ALTRON and NITRON engineered shapes as well as ceramic/ metal assemblies that can be welded in place of existing steel components, giving engineers freedom to worry about other parts of their FCCU turnaround. Once installed, Blasch’s highly abrasion-resistant ALTRON and NITRON materials far outlast traditional high alloy steel or hexmesh castables, making it easier for you to achieve financial performance objectives by optimizing catalyst efficiencies, maximizing cat cracker life and eliminating costly maintenance/replacement costs traditionally found in metallic components.
