How to design a surge drum for a gas feed with changing composition
(OP)
I am working on a project with a variable feed. 60% of the time it will be one composition and 40% of the time another. This happens every hour. I have been tasked with designing a surge drum to try to dampen the variation but I can't figure out how to approach this. Any help anyone can offer would be very welcomed. I have access to hydraulic software and the entire Aspen suite. Thanks

Probably should be sized to hold several hours of flow. Use a length long enough to ensure mixing has occurred by the time the flow has reached the opposite end, if the flow must be continuous.
You could probably reduce the length, if you can make that a batch mixing operation, ie. load a tank with a few hours of flow. Close it and open again when mixed.
Or do the same with two tanks and alternately draw from each one to make the op more continuous.
Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."
