    Does anybody know what the standard strategy of level control for the fractionator is?
    Is the level normally contolled on the feed coming in?

    Yes Sir,
    Level indication sets fresh feed flow requirements; once heaters flow passes are set, level controller takes care of recycle volume changes. It is recommended a soft tunning to allow some fractionator bottom level fluctuation (I have seem like 50-70% range) to avoid sudden changes of fresh feed rate.
