Abstract:
The invention relates to a cooling unit consisting of an exchange line capable of heating nitrogen originating from the system of columns by exchanging heat with the air to be cooled for the system of columns, and a cooling tower for the heat- and mass-exchange between the water to be cooled sent to the top of the tower and the nitrogen originating from a system of air distillation columns, the lower portion of the tower including an inlet connected to a nitrogen pipe, and the nitrogen pipe being connected to at least one exchanger body of the exchange line, which is capable of heating the nitrogen originating from the system of columns by exchanging heat with the air to be cooled for the system of columns, wherein the tower is arranged above at least one portion of the exchange line.
