Rheological behavior of oil sludge

Hafiz Abdul Ahad Qazi

The consumption and demand for rock oil area unit increasing dramatically with the fast development of trade and energy sector. As a result, rock oil refineries manufacture the best quantity of oily sludge fashioned at the lowest of storage tanks throughout oil storage operations that contains a severely negative impact on the storage capability and also the operational safety of the tank. this study focuses on the physical science of this complicated fluid from Algerian fossil fuel storage tanks. rheologic measurements were performed at totally different temperatures below steady shear and dynamic oscillometry exploitation AR-2000 Rheometer. The results obtained show that the sludge exhibits yield-pseudoplastic flow behavior at low shear rates, that is sufficiently delineate by the Herschel Bulkley model supported the quality error and coefficient of correlation values. However, quasi-Newtonian flow behavior happens at terribly high shear rates. the rise in temperature had positive effects on the rheologic properties of the sludge, as well as coefficient, shear stress, yield stress, complicated modulus, modulus and viscous modulus. The dynamic physical science studies have shown that the sludge material behaves a lot of sort of a solid than a liquid below all experimental conditions studied.
