摘要

1.1 AIR SEP -PROCESSS DESCRIPTION. 1.2 DIFFERENT TYPES OF AIR COMPRESSORS. 1.3 EVOLUTION OF COMPRESSOR TECHNOLOGY. 1.4 CENTRIFUGAL - PHILOSOPHY/DESIGN/OPERATIONS. 1.5 SOLUTION FOR AIR SEP OXYGEN PLANTS (20 TPD). 1.6 COMPARISON OF DIFFERENT TYPES OF COMPRESSORS. 1.7 QUESTIONS. 2.1 Atmospheric Air mainly consists of Oxygen and Nitrogen along with small quantities of water vapour, Carbon Dioxide & other inert gasses. 2.2 Atmospheric Air is sucked in by a multi stage lubricated Compressor through a filter and is compressed to the design pressure. 2.3 The compressed Air is then passed through inter coolers .Industrial Refrigerator, Moisture Separators ,and then to the Molecular Sieve Battery for removal of Carbon Dioxide, Hydrocarbons and Moisture from the process Air. 2.4 Process Air when further cooled through Heat Exchangers & expansion engine turns to liquid state and gets collected at the bottom of column. 2.5 Oxygen and Nitrogen from the liquid Air are separated due to difference in boiling points by distillation through a fractional column.
