Control Valve Sizing In Complex Hydraulic Circuits

If there is a process requirement to install a liquid level control valve followed by a temperature control valve upstream of an exchanger on the common discharge header which then branches to multiple lines that go to different destination with a flow control valve on each branched line. How to assign and distribute the available pressure drop to the level, temperature, and flow control valves?
Regards,

Can you put pictorial presentation of scheme envisaged? P&ID with stream data will be ideal.

Hi Vegeta ,
Your system is very complicated , lack of "freedom" ..
You may consider a more simple arrangement :
level control to stripper acting on the discharge to storage tank , no split range ;
TIC acting on the coolant , not on the flow from the column ,if possible
FIC , nothing special
