High purity nitrogen production process and installation |
摘要 |
<p>Ultra-pure nitrogen is produced in a process comprising separating air in an integrated plurality of columns. A nitrogen-enriched stream is elevated in pressure and thereafter contaminants and impurities are removed in an auxiliary column system which allows for the main column to efficiently operate below the required nitrogen product pressure, while including an ability to optionally obtain a normal purity nitrogen and a liquid nitrogen product. The process and installation remains efficient and economical in a relatively small scale installation to produce extremely pure nitrogen product. <MATH></p> |
