 This study deals with reducing energy requirement in multicomponent distillation processes using heat pump technique. Heat pump with and without split tower technique was considered for two ternary (Methanol-Ethanol-Water and Acetone-methanol-Water), and one quaternary feed systems (n-Hexane – MCP – Ethanol and Benzene)and many variables have considered  such as operating pressure, feed composition, and fractional recovery.  The separation was carried out using one configuration for each feed system according to their non-ideality.

The object of this research is to study the influence of Polyisoprene as additive on the properties of base lubricating oils.

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).
