ABSTRACT:
An apparatus for and a method of removal of particulate material and boiler-feed additives from pressurized, saturated steam, which apparatus includes a composite cartridge in which particulate matter is removed by a filter tube and boiler-feed additives are removed by contacting the filtered steam with a bed of a hydrogen-form, strong-acid, ion-exchange resin, and saturated, pressurized steam substantially free of particulate matter and volatile, alkaline, boiler-feed additives are recovered for use, for example, in food-preparation and sterilization purposes.
