Abstract
The apparatus is used to produce a product by low-temperature separation of a gas mixture, in particular air. It includes a direct contact cooler (3) for cooling the feed mixture, a purification apparatus (4) for purifying the cooled feed mixture and a low-temperature part (7). The low-temperature part (7) includes a main heat exchanger (8a) for cooling the purified feed mixture to approximately dewpoint temperature and a distillation column (9a) for low-temperature separation of the feed mixture. The direct contact cooler (3), the purification apparatus (4) and the low-temperature part (7) are arranged on one line (101).
