الملخص الإنجليزي

-Some crude oils are almost certain to be less convenient to handle, more costly, and less stable than the often already difficult substances in use today.

As viscosity increases, so do handling problems and capital requirement for equipment necessary to handle these materials.

System reliability due to the severity of the handling conditions may become a problem, heating requirements and the costs become important factors, and the difficulty of maintaining these materials under the required conditions for storage and use frequently becomes significant at high viscosities.

These materials are normally very high in caloric value content, but are extremely difficult to handle, therefore, it is important to find methods to handle these cruds to make it more stable and easily to use.

Non-Convential method for upgrading crude oil characterization (mixed of Basrah-Kirkuk crudes oil) using hydrodynamical coaxial turbo machine type rotary pulsation apparatus (RPA) implement ultra-high reliability in shearing rotor-stator operation and constructed from high toughness steel of the type (30CrMoV9).

Both directions of the rotor are designed to have a number of teeth uniformly distributed over the circumference of the rotor disc as well as the stator disc.

The analysis of the crude oil after acoustic-mechanical effect in RPA showed that increasing of recirculation time between 5 - 10 min with higher rotor speed (7610 rpm), leaded to increases the total productivity of light and intermediate petroleum fraction cuts from (30%) to (39%), increase in API gravity from (29) to (40), reduce flash point from (75◦C) to (54◦C) and reduce pour point from (-10◦C) to (-32◦C), thus providing better handling properties and then additional possibilities of being transported in pipe lines.

Also, the addition of linear alkyl benzene sodium sulfonate (LABS) as surfactant has been investigated, it improves the treatment of crude oil properties, decreases the shear stress of crude oil.

The results show that the API increased to (45), flash point reduced to (50◦C), pour point reduced to (-36 ◦C) and the yield of light and intermediate fraction increased to (40 vol.

%) within (10min) and (7610rpm).
