Types of distillation columns used for the four-column distillation of methanol

Thread Content

Methanol four-column distillation includes a pre-column, a pressurized column, an atmospheric column, and a recovery column. I was wondering if anyone knows what type these four towers are. I read in the materials that there are packed towers and plate towers, and among plate towers, there are mesh-type towers and floating valve towers. After looking up information, I saw that pre-towers can use floating valve towers. Has anyone worked in a factory? What are the common types of these four towers? O(∩_∩)O Thank you
