Abstract:
     The anticorrsion method for heat exchange between exchange gas and saturated gas features that part of exchange gas and low-temp saturated gas take part in parallel-flow heat exchange to quickly raise temp of saturated gas and make it become wet gas far from dew point, avoiding dew point corrosion, and the rest of exchange gas and temp-raised wet gas then take part in counter-flow heat exchange to further raise temp of wet gas to one required technologically. A parallel-counter-flow tubular heat exchanger or one big and one small tubular heat exchanger are used. It features no dew point corrosion, great heat exchange area.
