摘要
A Complex Fractionator contains a feed flow rate (5) that is controlled by the upstream unit and is pre-heated in a furnace (6). The fractionator (7) has a top, middle and bottom product. The fractionator overhead temperature is controlled with a Pl controller (8) moving the top reflux. The middle product draw temperature is controlled with a PI controller (9) moving the middle product draw rate A third Pl controller (10) moves the bottom product rate to control the fractionator bottoms level The bottom composition is measured with an analyzer (11).
