Purolator's Poroplate® hot gas filters are application engineered and manufactured to optimize your process.
nnnnBy tailoring the filters to meet the specific operating conditions of your systems, we provide filters that
nnnntolerate higher temperatures and offer greater throughput. In addition, Poroplate® hot gas filters provide
nnnngreater back pulse efficiency with no measurable product bleed through. The result: an optimized chemical
nnnnprocess system.
nnnnPOROPLATE® SINTERED WIRE MESH FILTERS
nnnnPoroplate® filter media are made from multiple layers of woven wire mesh sintered together into a rigid, durable, porous
nnnnstructure. Each wire mesh layer is chosen for a specific engineering purpose: filtration (particle size removal), flow drainage, or
nnnnstrength. Poroplate® filter media are sintered in porous panels which are then formed and welded into strong, self-supporting
nnnnfilter tubes.
nnnnENGINEERED SOLUTIONS
nnnnFor gas applications, we design Poroplate® elements to be surface-loading
nnnnfilters. In this configuration, the filtration mesh layer is located on the
nnnnupstream side of the media in the normal flow direction. Drainage and
nnnnsupport mesh layers are below. This design provides a filter with very little
nnnnpressure drop, affording the system operator longer on-stream cycles. As
nnnnthe particles contact the filter, they are retained on the surface of the filter
nnnnmedia, not deep in the pores as in ceramic or sintered powder elements.
nnnnWhen the elements are back-pulsed or cleaned, the retained particles (filter
nnnncake) release easily and the filter element returns to like-new condition.
nnnnOur rigid multi-layer design withstands constant back pulsing. The sintered
nnnnmedia will not tear, thus preventing catalyst or contaminant particles from bypassing downstream.
nnnnHot gas is often processed in environments reaching 900° C with high chlorine gases. Poroplate® filter tubes made in Inconel®
nnnnalloy have the metallurgical characteristics and mechanical strength to withstand this harsh working environment.
