1. A method for leak detection in a compressor system for an air separation unit, the method comprising:
determining a first pressure differential across a restriction in the compressor system via a first pressure differential indicator (PDI), wherein the restriction is disposed upstream of the compressor and comprises at least one of a surge flow cone, a strainer, a cooler, and a flow element;
converting the first pressure differential into a first flow measurement upstream of the compressor system;
determining a second pressure differential across another restriction in the compressor system via a second pressure differential indicator (PDI), wherein the another restriction is disposed downstream of the compressor and comprises another flow element;
comparing the first flow measurement and the second flow measurement to determine whether a leak exists between the first PDI and the second PDI in the compressor system.
