Reasons for the freezing of the deethanizer column
Thread Content
Operating temperature of the deethanizer: top temperature of -20°C, bottom temperature of 63°C. Float valve tray. The demethanization tower is a packed tower. Why does freezing always occur at the upper part of the deethanizer while the methane column is unaffected? Conduct a sample analysis to determine the water content. What is the mechanism behind the formation of frozen columns in oxidized compounds in cold zones?
Normally, problems with frozen towers are related to water; it’s the first time I’ve heard that there could be other causes as well； I would like to ask how you determine that it is an oxidized compound causing the freeze tower issue Or are there any other reasons other than the frozen tower? What are the specific symptoms?
Check the water issue thoroughly!
Hello, OP! I’d like to ask you some questions!
It’s usually carried together with water; how could ethane freeze, given its extremely low freezing point?
