Abstract
An air separation method which comprises supplying a precooled compressed air through a main heat exchanger to a rectification column, passing a recycle gas from the rectification column through the main heat exchanger for utilizing the cooling of the compressed air while discharging a portion of the compressed air flowing through the main heat exchange at a midway in the main heat exchanger to allow adiabatic expansion thereof and supply the air to the rectification column; which is characterized in that a pipeline on the low temperature side of the main heat exchanger at the position where the compressed air is discharged is used as the pipeline for the recycle gas flow through thereby increasing the heat exchange utilization of the recycle gas.
