Abstract

This air separation plant and the respective process comprise a main heat exchanger (10) consisting of block(s) of a first or a second block type (11, 12), each block of a block type has the same internal structure concerning the two main passage groups (36, 40; 37, 41) for warming two main returns streams, the blocks of the first and second types both comprising one or more identical or similar passage groups for cooling feed air (15a, 15b) directed to the distillation system, the block(s) of the first type (11) comprising a passage group for guiding and warming pumped liquid oxygen (36, 37) and a passage group for impure gaseous nitrogen (31, 13) withdrawn from an intermediate point of the low-pressure column (18b), the block(s) of the second type (12) comprising a passage group for guiding and warming pumped liquid oxygen (36, 37) and a passage group for gaseous nitrogen (22, 23, 14) withdrawn from the top of the low-pressure column (18b), but no passage for impure gaseous nitrogen (31, 13) withdrawn from an intermediate point of the low-pressure column (18b).
