Abstract (en)
A cryogenic air separation unit (10) comprises a number of compression stages (12, 14, 16) at least one of which is driven by two or more expander turbines (18, 20, 22) acting in parallel or series and linked for driving one or more compression stages (12) via a common or bull gear (34). One of said compression stages (12) may be linked directly to one of the expander turbines (18) via a gear (32, 36) which acts to form the output gear of the turbine and the input gear of the compressor. <IMAGE>
