ULTRA-LOW PRESSURE DROP FLUID FILTERS AND RELATED METHODS

A method may comprise: sintering a particulate mixture comprising binder particles at about 5% to about 75% by weight of the particulate mixture and fugitive particles at about 25% to about 90% by weight of the particulate mixture, thereby forming a porous mass; and substantially removing the fugiti...

Zusammenfassung:	A method may comprise: sintering a particulate mixture comprising binder particles at about 5% to about 75% by weight of the particulate mixture and fugitive particles at about 25% to about 90% by weight of the particulate mixture, thereby forming a porous mass; and substantially removing the fugitive particles from the porous mass, thereby forming an ultra-low pressure drop (ULPD) porous mass with fugitive particles at 0% to about 5% by weight of the ULPD porous mass.
