摘要
Enclosures (53, 55a-55f), to contain a protective gaseous atmosphere, are located around valve seals. An Independent claim is included for the corresponding method preventing or limiting contamination of plant adsorbent by ambient air impurities. Preferred Features: To maintain a protective gas atmosphere, an enclosure (53) surrounds each valve sealing and actuation system. Its casing opening (56) admits protective gas from a supply line (57). This line is connected to a blanketing gas source, to feed the enclosure. The source is a treatment vessel for gas, a gas storage reservoir or an instrument air production unit. The casing is formed by attached walls. It comprises a peripheral wall (55a-55d), base (55f) and cover (55e). Part of the enclosure is formed by the valve, the rest comprising added walls. The plant is a pressure swing adsorption (PSA) or temperature swing adsorption (TSA) plant.
