Separation processes are highly influenced by medium in which separation is performed, particularly its rheological properties. One of the most important rheological parameter of medium is viscosity. Many researchers have noted the primary role of viscosity in separation processes. During classification of milled raw, with an increase in the viscosity of the medium (up to a certain limit), the overall productivity of the hydrocyclone increases and the distribution of liquid volumes leaving through the apex and vor...

Year by year, the growth of the share of heavy oils in the total volume is steadily increasing. For development of highly effective methods for its processing, approaches to modelling their properties should be elaborated. This thesis is dedicated to deriving and substantiating a formula for calculation of the velocity field in the round pipe volume as adjusted for rheological features of the flow of heavy oil suspensions. The suggested approach is based upon rheodynamics equations reflecting the flow of a rheolog...

Forecasting of viscosity value in blending of oil products is an important production task, settlement thereof influence the selection of its pumping mode and a number of other technological aspects. Quite high-precision models have been offered for the objects similar in viscosity, but at significantly different value of viscosity for the mixture components there is a great error. Graphic diagrams of interaction of petroleum-bitumen suspension-kerosene mixture viscosity at various ratios of its components and var...
