How to design the process flow when the flow rate changes?
Thread Content
In the process design I am engaged in, the system flow rate changes. Should the equipment be designed based on the average flow rate or the maximum flow rate? Thanks!
In most cases, it should be designed for maximum flow. . If the flow rate range is determined before design, then the design should be based on the maximum flow rate. Your question is not clear. . Design requires detailed analysis of specific problems. It is very blind for you to ask a general question like this. You should at least explain your specific design before asking.
Generally, device design has an operating flexibility. When selecting the equipment design flow rate, the maximum flow rate and minimum flow rate should be included in the operating flexibility.
The question is a bit vague. Should I choose a flow meter or equipment?
Under normal circumstances, the maximum flow demand should be met, while economical and practical operational needs should also be taken into consideration.
Equipment, pipes, instruments, etc. should all be designed according to the maximum flow rate
