Course Content (Syllabus)
Τhe aim of the Unit Operations I course is the study of the principles involved in the preliminary design of distillation columns, absorption and extraction towers as well as, cooling towers. The design of distillation columns is performed as an example of a stagewise process. Analytical and graphical methods are employed to calculate the number of theoretical trays in continuous and batch binary distillation. Tray and column efficiencies are discussed, while simplified methods are employed for the design of multicomponent distillation. Differential-contact processes are examined in the chapter of absorption. The number and height of transfer units are calculated to obtain the height of the packing material in the column. Column efficiency is also discussed. For the design of liquid-liquid batch and continuous extraction processes of non-miscible and partially miscible solvents, analytic and graphical methods are again employed. The design of cooling towers is performed as a good example of simultaneous mass and energy transfer. Design of water-air cooling tower.
