Choose Design... |
Problem Statement: What are some modeling considerations for plant shutdown processes? In plant shutdown scenarios, assuming all the specs still making engineering sense (some of them zeros since the plant is shutting down), can Aspen Plus Dynamics simulate the process until all flows reduce to zero? | Solution: Here are some insights and rules of thumb regarding shutdown simulations:
(1) Typical difficulties encountered in shutdowns may be:
phase flipping
reverse or bi-directional flow
too large heat transfer due to fixed duty
complete drain hence zero holdup (zero pressure or zero density)
controller fails
(2) If a... |
