LMTD for Steam Heated Reboiler
LMTD for Steam Heated Reboiler
(OP)
I am a 30+ engineer and am a little embarrased to ask.
But how does one handle Q = U*A*LMTD for a Steam Heated Reboiler?
The main issue seem to be LMTD determination
The process side is a constant boiling temperature.
Neglecting steam superheat & steam subcooling, the steam is a constant condensing temperature.
The greater temperature difference equals the lesser tempeature difference
The arithmetic LMTD = (Greater DT - Lesser DT)/LN [(greater DT)/lesser DT]
= (0) / LN [1]
= (0) / (0)
Any comments would be appreciated
