Non-Classical Level Control Of The Utc Distillation Column, Mevan Ranasinghe
Non-Classical Level Control Of The Utc Distillation Column, Mevan Ranasinghe
Honors Theses
This paper researches the enhancement of accuracy for level control for an operational distillation column. This was achieved through an analysis of both controller and sensor components. The UTC distillation column reboiler level control, like any control system, has multiple sources of error resulting in increased imprecision and inaccuracy. Several fundamental inaccuracies in processing of data were identified and then minimized by the introduction of a non-linear mathematical model prior to any actual controller development. This provides more accurate level measurement and a base for developing accurate controllers.In exploring the effectiveness of alternative controllers, two non-classical controllers are considered in …

A Continuous Distillation Operation At The University Of Tennessee At Chattanooga, David H. Cummins
Honors Theses
This paper describes the work done on the design, construction, monitoring, and control of a distillation column. This work was done as a Departmental Honors Project in the School of Engineering at The University of Tennessee at Chattanooga. The column has been completed and the various tests performed with the column have produced satisfactory results. The column parameters are monitored and controlled by automatic controllers with manually adjusted set points. In addition to this, micro-computer based control for the column has been designed, however implementation of this control has not yet been achieved.
