Linde double coulmn rectifier
a single/double column:
Based on his air liquefaction principle Carl von Linde constructed the first air separation plant for oxygen production in 1902, using a single column rectification system.

In 1910, he set the basis for the cryogenic air separation principle with the development of a double-column rectification system. Now it was possible to produce pure oxygen and pure nitrogen simultaneously:

Below the low pressure column a pressure co-lumn was installed. At the top of this column pure
nitrogen was drawn off, liquefied in a condenser and fed to the low pressure column serving as reflux. At the top of this low pressure column pure gaseous nitrogen was withdrawn as pro-duct while liquid oxygen evaporated at the bottom of this column to deliver the pure gaseous oxygen product. This principle of double column rectification combining the condenser and eva-porator to form a heat exchanger unit is still used today.
Condenser/reboiler
The principle of double-column rectification is characterized through the combination of condenser and evaporator to form a common heat exchanger unit.

By this means the rectification is divided into two separate areas with different pressures.
