| Abstract: | Fractionation of Tall Oil as an Example of Optimization of Conventional Packed Columns The present communication records a simple calculation for optimization of packed columns in an example of layout of columns for fractional distillation of crude tall oil into the main products, i.e. fatty acids and resin acids. This calculation requires, apart from knowledge on the temperatures stability of the material, only the HETP value, which is the height of chosen packing material equivalent to one theoretical plate. An arrangement of three columns is necessary for complete separation of crude tall oil in continuous manner. In the example shown, calculation of the first column for a capacity of 20 000 t per year is given. |
