Froth Treatment Explained | Oil Sands Magazine

Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

Filter Separators: A filter separator usually has two compartments.The first compartment contains filter-coalescing elements. As the gas flows through the elements, the liquid particles coalesce into larger droplets and when the droplets reach sufficient size, the gas flow causes them to flow out of the filter elements into the center core.

Chapter Gravity Separation

Separation of gold by density difference dates back to at least 3000 BC as depicted in writings from ancient Egypt. The principle employed in gravity separation goes back further in time to the formation and weathering of the rocks and the releasing of the minerals they contain and the transport of the mineral grains by heavy rains.

Gravity filtration - Wikipedia

Gravity filtration is a method of filtering impurities from solutions by using gravity to pull liquid through a filter. Ther two main kinds of filtration used in laboratories are gravity and vacuum/suction. Gravity filtration is often used in chemical laboratories to filter precipitates from precipitation reactions as well as drying agents, inadmissible side items, or remaining reactants.

To effect a separation on any gravity separator, the same principles apply. Once they are understood, it is usually a simple step to adjust a gravity separator to produce optimum separation. The term "Gravity Separator" is a contraction of the proper name "Specific Gravity Separator," which …

Oil/Water Separation: State of the Art

This mode is similar to membrane filtration and is covered in that discussion. Centrifuge—As mentioned, gravity separation is an integral part of the coalescence process. In centrifugal coalescence, fibrous material is used as the coalescing medium, but the final gravity separation of the oil and water phases is enhanced by centrifugation.

Separation of Mixtures< matter< chemistry< high school ...

Gravity Separation. In gravity separation, a mixture of two immiscible liquids can be separated using a separating funnel, the working of which is based on the differences in the densities of the liquids. The heavier liquid which settles below is drained out first from below the funnel into a beaker, and then the lighter liquid is drained out ...

Gravity Separation | Hazen Research

Hazen's gravity concentration facilities are among the finest in the world. Our laboratories contain small jigs, shaking tables, a Knelson concentrator, a Mozley vanner, and heavy-media separation equipment. Preliminary closed-circuit tests can be made with as little as a few kilograms of feed material.
