The aim of this research is to study the packed bed using theoretical methods and experiments. Five types of glass spheres were used which represent the packed bed with diameters of(d972, d2 = 10.164, d3= 14.772, d = 20.614,d54 = 25.448 mm).The theoretical methods which were given by latif consist of calculating the pore diameter, mean pore diameter and the probability due to (number,length, area, and volume).
Blending of oil stocks with hydrocarbons form non-ideal mixtures, for which excess volumes can be positive or negative depending to the nature of species.Gas oil mixed with nine petroleum fractions or individual hydrocarbons consisting of aromatics, and paraffinic nature in addition to an alcohol and a ketone. The systems have been subjected to density measurements at two temperatures. The results are reported in terms of excess volume, VE .
Packed beds are used in many process industries (e.g. Adsorption, Absorption,Distillation, and Filtration).
