FIELD: process engineering.
SUBSTANCE: in compliance with this method, flow 10 of the mix of vapor and fluid flows from first heat exchanger 101 into distribution vessel 12 via several inlet branch pipes 14. Said distribution vessel 12 comprises two or more outlet branch pipes 16 connected with second heat exchanger 102. Note here that liquid portion of mixed flow 10 accumulates in first bottom section of distributing vessel 12 while vapor portion accumulates at top section of said vessel. Fluid flows from first bottom section into outlet branch pipes 16 via one or more fluid outlets in every outlet branch pipe 16 communicated with first bottom section. Vapor flows from second top section into outlet branch pipes 16 via one or several vapor outlets communicated with second top section. Note here that every of two or more outlet branch pipes of distributing vessel are connected with pipe bundles in second heat exchanger 102. Proposed device comprises several heat exchangers communicated via distributing vessel and bundle of pipes.
EFFECT: increased heat exchange surface inside heat exchanger.
