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