FIELD: heating systems.
SUBSTANCE: invention refers to cryogenic separation of mixture of gases, namely air. Plant consists of direct-expansion cooler (3) for cooling base mixture of gases, cleaning device (4) for cleaning cooled base mixture of gases and low-temperature compartment (7). Low-temperature compartment consists of main heat exchanger (8a) for cooling cleaned base mixture of gases approximately to condensation temperature and distillation column (9a) for cryogenic separation of base mixture of gases. According to invention, direct-expansion cooler (3), cleaning device (4) and low-temperature compartment (7) are located in one line (101) in proposed plant.
EFFECT: use of invention will allow optimising the arrangement of the plant and increasing its economy.
