Roza M., Duss M., 2018, Troubleshooting Distillation Columns Unexpected Causes for Malfunctioning Columns, Chemical Engineering Transactions, 69, 469-474.
The cause of columns performing below expectation is often intuitively attributed to issues with column internals. But there are also other reasons. Two cases are presented, the first shows how to properly deal with trapped inert gases during startup and the second case shows how reversible reactions can affect separation performance and how apparent performance loss in such situations can be overcome.
