초록

A process is provided for supplying nitrogen from an on-site air separation plant providing at least oxygen as a product, which entails feeding an air feed stream to an instrument-air compressor which is oversized relative to compressed air needed to feed an instrument controlling the plant, feeding at least a portion of the compressed air stream from the instrument-air compressor to a nitrogen membrane separator, thereby providing a stream of nitrogen product, and venting an oxygen-enriched air stream from the membrane.

청구항

A process for supplying nitrogen from an on-site air separation plant providing at least oxygen as a product, said air separation plant comprising means to feed air to air separation means which separates oxygen from nitrogen to produce at least oxygen as a product, instrument-air means dedicated to operate or control, or operate and control the plant during at least certain periods of time during which the air separation occurs, the instrument-air means being actuated by compressed air and instrument-air compressor means to compress air and to generate ...
