Abstract
Modeling and Control of Heat Integrated Distillation Columns A Case Study ABSTRACTThis paper is concerned with the modeling, simulation, and control of heat integrated distillationcolumns. The widely used industrial separation of benzene, toluene, and m-xylene is consideredas a case study. The impact of heat integration is analyzed from an energy savings viewpoint.Heat integrated distillation columns are generally more complicated from a control viewpointbecause of the greater degree of interaction among the columns. Thus, different controlstructures, ranging from feedback only to more sophisticated ones such as feed forward andcascade, and tuning methods are devised and compared from a performance viewpoint whenproduct composition setpoint changes or feed rate and feed composition disturbances areintroduced. It is found that the more sophisticated control structures result in excellent controlperformance for the heat integrated columns when compared to feedback control only. Extensiveuse of Aspen Engineering tools is made to facilitate project execution and experiences arepresented. The paper also focuses on project management and planning techniques employed tomeet a desired project completion timetable.Note: Would like this student led paper to be considered for presentation.
