Description
The mixed refrigerant turbo Brayton cycle with neon and helium was initially designed to cool the beam screens of the FCC in a temperature range from 40 K to 60 K. The current cryogenic design of this cycle for the FCC-hh can use refrigeration above 25 K for other purposes as well, e.g. for the cool-down of the magnets, thus saving large amounts of LN2 required otherwise, or transient operation which occurs during the beam cycles. These operations force a considerable load change to the Nelium cycle. This presentation covers strategies for both scenarios. Furthermore, the acquisition of the cost intensive neon is covered.
