nnnn

Purolator's Poroplate® hot gas filters are application engineered and manufactured to optimize your process.

nnnn

By tailoring the filters to meet the specific operating conditions of your systems, we provide filters that

nnnn

tolerate higher temperatures and offer greater throughput. In addition, Poroplate® hot gas filters provide

nnnn

greater back pulse efficiency with no measurable product bleed through. The result: an optimized chemical

nnnn

process system.

POROPLATE® SINTERED WIRE MESH FILTERS

nnnn

Poroplate® filter media are made from multiple layers of woven wire mesh sintered together into a rigid, durable, porous

nnnn

structure. Each wire mesh layer is chosen for a specific engineering purpose: filtration (particle size removal), flow drainage, or

nnnn

strength. Poroplate® filter media are sintered in porous panels which are then formed and welded into strong, self-supporting

nnnn

filter tubes.

nnnn

ENGINEERED SOLUTIONS

nnnn

For gas applications, we design Poroplate® elements to be surface-loading

nnnn

filters. In this configuration, the filtration mesh layer is located on the

nnnn

upstream side of the media in the normal flow direction. Drainage and

nnnn

support mesh layers are below. This design provides a filter with very little

nnnn

pressure drop, affording the system operator longer on-stream cycles. As

nnnn

the particles contact the filter, they are retained on the surface of the filter

nnnn

media, not deep in the pores as in ceramic or sintered powder elements.

nnnn

When the elements are back-pulsed or cleaned, the retained particles (filter

nnnn

cake) release easily and the filter element returns to like-new condition.

nnnn

Our rigid multi-layer design withstands constant back pulsing. The sintered

nnnn

media will not tear, thus preventing catalyst or contaminant particles from bypassing downstream.

nnnn

Hot gas is often processed in environments reaching 900° C with high chlorine gases. Poroplate® filter tubes made in Inconel®

nnnn

alloy have the metallurgical characteristics and mechanical strength to withstand this harsh working environment.
