Selection of hydrogen fluoride evaporation and heating equipment
Thread Content
Selection issues for hydrogen fluoride evaporation and heating equipment: My hydrogen fluoride vaporization system involves cooling the crude acid first and then heating it to cause vaporization. Liu Liang: 1500 kilograms per hour, with a required heating temperature of 80 degrees. The equipment originally designed was made of carbon steel, but it doesn’t work well. I would like to ask experienced professionals in this field: Can graphite equipment be used? How is the lifespan?
Why isn’t anyone answering? I seek advice from an expert!
Carbon steel will do; we couldn’t use it before, but by using a little trick, now an evaporator has been in use for over a year without any problems
Why aren’t carbon steel reboilers effective? Don’t use too high a heating temperature; a smaller temperature difference is sufficient
Carbon steel won’t work, right? Pure HF will do, but aqueous HF definitely won’t; graphite has to be used. . .
