Centrifugal Compressors for Air Separation Units
While air may be free, the air separation process is not. Producing industrial gases requires a great deal of energy, making the need for an efficient compressed air system critical to plant success.
To produce industrial gases such as purified nitrogen or oxygen, atmospheric air is compressed, cooled, and separated in a distillation column or cold box. Once cryogenic separation is complete, the gases are used in other processes or compressed for storage and/or transportation.
The gases produced during this process can be used in a variety of areas including the production of chemicals and petrochemicals, liquefaction of natural gas (LNG), clean dry air for electronics manufacturing, production of synthetic liquid fuel from coal (CTL) or natural gas (GTL), integrated gasification combined cycle (IGCC) power plants or liquefaction of nitrogen for distribution. As a key component of the separation process, compressed air systems at air separation plants must be reliable and energy efficient to maintain low operating costs.
FS-Elliotts comprehensive product portfolio and engineering capabilities provide competitive solutions for highly customized as well as standard projects.
The flexibility of FS-Elliott air compressors makes them ideal for serving various roles in an air separation plant including main air compressors (MAC), booster air compressors (BAC), nitrogen gas compressors (GAN), nitrogen recycle compressors (NRC), and clean compressed dry air compressors (CDA).
Additionally, FS-Elliott has the capability to provide multiple process combinations, such as MAC/BAC, MAC/BNC, and MAC/GAN. By offering superior operating life cycle costs, FS-Elliott compressors allow customers to quickly gain their return on investment.
Due to a modular plant design, the compressors needed to be minimal in size but capable of high-efficiency production.
Three configurations were provided including low-pressure, high-pressure and combination air/nitrogen machines.
Customer reduced capital expenditures and increase overall efficiency by combining the air and nitrogen processes in one machine.
