Material selection for high-chloride ion heat exchangers
Thread Content
I would appreciate it if the experts on this forum could advise me on the material suitable for heat exchangers, as well as which type of heat exchanger would be best. Hot side wastewater: inlet/outlet pressures 82/67; cold side inlet/outlet pressures 67/82. Heat transfer capacity: 910 KW. The design pressure for both sides is 0.2 MPa. The characteristics of the wastewater are as follows:
The most cost-effective option would be a heat exchanger using 316L plates, I guess
Consider a detachable spiral plate heat exchanger made of 2507 duplex steel.
The terminal temperature difference of this water-to-water heat exchanger is 0, so its efficiency will be very low
It is recommended to use the duplex steel S22053; if the medium contains particles, spiral plates should be used instead
