Abstract
Abstract This paper explores the design methods for process exhaust duct systems, including velocity method, the equal friction method, the static regain method and the T‐method, and produces actual case designs and system simulations to compare the applicability of respective design methods. The study shows that none of the methods are able to meet the demand of cost optimization under the constraints of duct size and velocity, and the requirement of pressure balance. Dynamic programming is therefore proposed. The results show that dynamic programming is better than the other methods. It is able to achieve the optimization of life‐cycle cost while satisfying all constraints (flow rate, duct size, velocity and pressure balancing). The differences between the design and simulation results using dynamic programming are much lower than those of other methods. Thus a process exhaust duct system that approximates the actual operation best may be designed using dynamic programming.
