Sub-Micron Filter for High Temperature & Hazardous Process Environments

pfgpr14-image.jpgA white paper from Porvair Filtration Group describes the development of a micro porous sintered metal-ceramic membrane filter capable of absolute filtration to 0.5 microns in noxious or hazardous environments at temperatures of 500 °C and beyond.

The process industry demands filters that can withstand the most extreme and aggressive conditions of temperature, pressure and corrosion, whilst safeguarding operators and systems from particulates and ensuring environmental protection. As precious metal catalysts used in industrial processes become ever more expensive and are used in greater amounts, fine filters capable of withstanding the process environment offer a viable route for higher yield recoveries.

Most porous metal filters are incapable of removing particles smaller than 4 microns.  The Sinterflo® filters, under development by Porvair, are shown to improve filtration by almost an order of magnitude.  Scanning electron photomicrograph and porosimetry, bubble point, permeability and efficiency data, for both gaseous and liquid environments, are presented.
