Heat exchanger issues
Thread Content
The material is acidic, consisting of about 80% dichloroethane and 15% DMF, with the remainder being unknown substances. A graphite heat exchanger is considered; however, phenolic resin is not resistant to DMF. What type of heat exchanger should be used?
Many resins are sensitive to solvents; it is advisable to adjust the material to a neutral or weakly alkaline condition before considering using it in a heat exchanger. If this is not possible, then enamel-coated heat exchangers, PTFE tube heat exchangers, or heat exchangers made of special alloys could be considered
The heat exchanger for 2205 should work fine!
Are you interested in non-metallic graphene heat exchangers? (Corrosion-resistant, heat transfer coefficient similar to that of metals)
You can try an impregnated tetrafluorographite heat exchanger! The heat exchange efficiency remains unchanged, and the corrosion resistance is even better!
The corrosion caused by dimethylformamide is quite noticeable; it’s best to avoid using phenol-formaldehyde and furan. Impervious graphite impregnated with tetrafluoroethylene is a good choice. Feel free to contact me if you have any questions!
