Hi,

i'm working on figuring out how much flow of steam we need in our reboilers

currently the steam temp to our reboilers is much higher the design temp of the reboilers which is affecting the efficiency of the reboilers

but working on the flow to the reboilers is the key solution. i need to change the set point of flow to the reboilers?

the calculations will involve LMTD and Q=mU(DeltaT)

but if someone know the procedure for the calculation

thank you

Very vague. Any details? What are you boiling? Heat flux needed?

What is design T? How much above are you?

Set point controlling what? etc.
