Application scenarios of floating-head heat exchangers

2017-09-14 View Original

Thread Content

I have seen heat exchangers made of graphite that are floating-head type. Today I saw a metal device that was also of the floating-head type, which puzzled me greatly. Cooling water flows through the tube side of the heat exchanger, with an operating pressure of 0.5 Mpa and a temperature of 40 degrees. H2 is used in the shell side, with an operating pressure of 3.5 Mpa and a temperature of 83 degrees.

Floating-head heat exchangers are widely used in the petrochemical industry: lol

But I don’t understand why a floating-head type was chosen for this occasion.

One is 40 degrees, the other is 83 degrees; the temperature difference isn’t that large, is it?
