In the fractionator column JET A1 side stripper some time I faced level fluctuating before the hot vapor from the side stripper to to fractionator column temperature normally more than 205 deg C the side stripper level is normal if the temperature of the hot vapor retune less than 200 deg c level will start fluctuating.What's the reason and how to solve it? I have to increase side stripper reboiler or draw rate?
