1996). The shorter life of sintered fiber elements in comparison to the etched disk element is
compensated for by a significantly lower cost per element. Sintered metal fiber elements in
amine service are typically rated at 10 microns absolute (Clark, 1996). Since these systems
are completely automated, operator acceptance problems are avoided. A sintered metal fiber
element housing for amine filtration service is depicted in Figure 3-26b. F'TI Technologies
of Newbury Park, CA, manufactures sintered metal fiber filters for amine service, while Pall
Well Technologies, Inc. of East Hills, NY, makes similar automatic sintered metal powder
and sintered metal fiber filters for amine service. Pall also markets an automatic backflush
amine filter which uses non-metallic filter elements (Cathcart, 1996).

Activated Carbon Filtration

When foaming is caused by surface-active contaminants or dissolved or emulsified high
molecular weight organic compounds, these agents may be eliminated by passage of the
