PPT Expands Drying and Emissions Control Capabilities

Powder Processing & Technology (PPT), a processor of powdered materials for North America’s largest materials companies, announces a significant expansion of its capabilities and capacity.

The company, which serves inorganic and ceramic materials processors, has installed advanced spray drying capabilities which enable the spray drying of ceramic and inorganic powders down to 50 µm granule size with precise uniformity.  

This capability is required by manufacturers in 12 critical industrial sectors, including electronic powders, minerals processing, oil field materials, refractory materials, catalyst manufacturing, and materials recovery. Spray drying converts an aqueous solution into a free-flowing powder with an average particle size of 50-200 microns.

Simultaneously, the company has substantially increased its ability to handle NOx emissions from its thermal processes, allowing it to serve the broadest range of materials companies.

Specifically, a ceramic catalyst filter system engineered and manufactured by Tri-Mer Corp. (Owosso, MI) is now operational. As a direct result, PPT can now handle the broadest range of conditions and concentrations of evolved NOx.  

Current capabilities of the equipment include powdered feedstock and formed materials at temperatures up to 1100°F. The system is capable of handling NOx emissions in the range of 2-50 lb/hr with NOx destruction efficiency adjustable up to 95%. The Tri-Mer equipment can be easily modified to remove sulfur oxides (SOx), hydrochloric acid gas (HCl), dioxins, mercury and other pollutants.  

The Tri-Mer unit also captures particulate – PM10, PM2.5, and submicron PM – with over 99% efficiency. Tri-Mer’s emissions technology is in operation on large kilns and furnaces across the U.S and Europe.
