Definitions
- the invention relates to a method and apparatus for variable recovery of a compressed gas product by cryogenic separation of air.
- the distillation column system of such a system can be designed as a two-column system (for example as a classic Linde double column system), or as a three or more column system. It may have, in addition to the columns for nitrogen-oxygen separation, other devices for obtaining highly pure products and / or other air components, in particular noble gases, for example argon recovery and / or krypton-xenon recovery.
- the product stream is then "pseudo-evaporated".
- the product stream may be, for example, an oxygen product from the
- a high-pressure heat transfer fluid is liquefied (or pseudo-liquefied when it is under supercritical pressure).
- the heat transfer medium is frequently replaced by a part of Air formed, in the present case of the "second partial flow" of the compressed feed air.
- DE 102010052545 A1 shows a stationary internal compression method, in which an air stream in the main heat exchanger warmed up and to the main air compressor
- the invention relates to systems in which all of the feed air is at a pressure well above the highest distillation pressure prevailing inside the columns of the distillation column system (this is normally the case)
- High-pressure column pressure is compressed.
- HAP processes HAP - high air pressure
- the main air compressor is regularly the only external energy driven machine for compressing air.
- a “single machine” is understood to mean a single stage or multi-stage compressor whose stages are all connected to the same drive, with all stages in housed in the same housing or connected to the same gear.
- An alternative to such HAP methods is the so-called MAC-BAC
- Main heat exchanger It is located downstream of the main air compressor in one
