Tar Sands Crude Shipping Meets the Great Lakes?

Tar sands crude is a heavy crude oil found in the environment within a mix of sand, clay and bitumen. Because of its viscosity, lighter hydrocarbons (e.g. benzene) are added to the tar sands to enable it to flow through pipelines.1 Experience has demonstrated — as is detailed

Chapter two– Petroleum &petroleum product

Viscosity and Pour Point Viscosity and pour point determinations are performed principally to ascertain the handling (flow) characteristics of petroleum at low temperatures. There are, however, some general relationships of crude oil composition that can be derived from pour point and viscosity data.

Viscosity of Coal Tar - QS Study

Viscosity of fluids can be determined from the rate of exit of a sample fluid under gravity through an orifice. Time of the order of decades is required for a value of the viscosity of a coal tar pitch to be obtained in this way. At the University of Queensland in 1930 such an experiment was commenced [8], and it is still in progress!

Managing Viscosity of Crude Oil - Merus Oil and Gas

In case of the crude oil the ingredients of the crude determine its viscosity. Especially tar or asphaltene, increase the thickness of crude. The higher the viscosity, the more difficult it is to transport through a pipe. Pumping highly viscous liquids can be very energy-intensive and wearing for machines and pipes.
