Relationship between weir length and tower diameter under four-overflow conditions
Thread Content
When designing atmospheric and vacuum distillation columns, floating valve columns are chosen. What I can find currently are empirical relationships between the length of the underflow weir and the column diameter for single and double underflows, but I would like to know the relationship between the underflow weir length and column diameter for four underflows.
