Apparatus for the low-temperature separation of a gas mixture, in particular air

摘要

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 ( 8 a) for cooling the purified feed mixture to approximately dewpoint temperature and a distillation column ( 9 a) 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 ).
