Dear Members,
I have a question that make me confused a little bit.
As known, as a widely accepted method, "unbalanced heat load" is used by many (or most) designers to estimate relief load for distillation column, particularly for scenarios like general electric failure, reflux failure and so on.
While I cannot find any definite message in API 521 to support this method.
Can anybody of you shed some lights on this? thanks.
