A method for the cooling of a first material stream to be heated by means of a second material stream in an olefin plant for the production of olefins

摘要

The invention relates to a method for cooling, in particular condensation, a first material stream (s) to be heated by means of at least one, in particular to be evaporated, second material stream (s'') in an olefin plant for the production of olefins, comprising the steps of: introducing the second material stream (s'') into a by means of a first shell (20) limited first jacket space (m) of a device of the olefin plant, in which a first plate heat exchanger (10) is arranged, so that the second material stream (s'') in the first jacket space (m) a the first plate heat exchanger (10) surrounding bath (2) is formed and in the first plate heat exchanger (10) rises, the introduction of the flow to be cooled first material stream (s) in the first plate heat exchanger (10), so that said first material stream (10) in the counterflow to the second material stream (s'') in the first plate heat exchanger (10) is supplied, and in indirect heat exchange with the second material stream, (s''), and, as a result, cooling of the first material stream (s), in particular condensation of the first material stream (s) and heating, in particular, evaporation, of the second material stream (s'').
