When hydrogen fluoride gas at room temperature is cooled from room temperature to -75 degrees, what type of heat exchanger is suitable?

Pure PTFE impregnated graphite heat exchanger. You can contact me if needed. Station message or QQ is fine: 1915076993

Use a graphite heat exchanger or a ceramic-lined heat exchanger

Using Halar ECTFE as an anti-corrosion coating for heat exchangers

Yes, the F ions in hydrogen fluoride have strong oxidizing properties

Halogens can corrode stainless steel! Prone to intergranular corrosion :)
