About PTFE condenser
Thread Content
Does anyone know about the materials we use? They are very corrosive but when using graphite condensers the materials are colored. So we want to use a PTFE condenser but I heard that the tube length of the PTFE condenser is very thin. The melting point of our material is over 40 degrees and we are worried that the material will block the inside. I wonder if we can still choose a PTFE condenser tube. Does anyone know about this?

Each heat exchanger has its own advantages and disadvantages. Graphite heat exchangers have good resistance to hydrochloric acid, but are not resistant to strong alkali. Temperature and pressure resistance are limited. Tantalum has good acid resistance, but is not resistant to strong alkali and hydrofluoric acid. The temperature and pressure resistance is relatively high. Enamel heat exchangers are similar to tantalum, but the pressure is not very high. Pay attention to temperature shock issues when using them. Another shortcoming is that the heat exchange performance is not good. The overall performance of silicon carbide heat exchangers is acceptable, it is resistant to HF acid and has high heat exchange efficiency, but the current technology on the market is uneven. As you said, PTFE heat exchangers may become clogged and have poor heat exchange performance. Each of the above heat exchangers has advantages and disadvantages, and it is best to use it correctly.
