Has anyone seen a column, which does not have a PSV sized for a blocked outlet scenario like stated above?,
Yes with system fully rated. But somehow a PSV still required for other scenario such as Fire case, excess process heat input, etc...
QUOTE
can instrumentation , or interlocks reduce the total relief?
I would say designer may used instrumented protective system to eliminate credible scenario with large relieving rate.
Mechanical interlocks has been considered as an measure to eliminate credible scenario with large relieving rate.

Is it possible to have a tower with no relief valve on the overhead line?
Hardly see it...
