As because pressure is active specification, flow rate stick on one. I wanted to give new flow rate, but when process is running it is again going back to the first flow rate. So I can change flow rate in dynamic to try different flow rates for my flow sheet ? for example if it is simple feed stream of nitrogen and oxygen passing through compressor to cool done . So pressure is 200 bar, temperature 100 K. Starting flow rate was 10kgmole per hour. Now I want to do at 20, but it is impossible to change it.

Hi!
you cannot change it in such rude way. it is impossible. You can change parameters of your system (e. g. k value of valves) to change flow rate. but you cannot change pressure and flow rate simultaneously. you can understand reasons of it from pressure-flow equations

Increase the source pressure, open a control valve. That is how it happens in the real world.
