“…Other methods are also used in the NFT process for better results. For instance, inclined plate separators (IPS) used in the NFT settling units significantly reduce the settling distance of the solids and the need for centrifugation . In the following, chemical treatment methods are discussed in more detail as chemical demulsification is the only method commercially applied for the removal of fine solids and residual water in the NFT process.…”

Petroleum refining and downstream facilities cannot handle excessive water, solids, and salts as they increase the refining operational costs and damage the equipment through various interfacial phenomena such as fouling, corrosion, and catalyst poisoning. Thus, producers must dehydrate the crude and remove the fine solids in the extraction and treatment processes. However, the presence of interfacially active species in the bitumen composition such as asphaltenes, resins, and fine solids results in the formation of stable emulsions that are difficult to treat. This phenomenon is indeed the case in the bitumen froth treatment, where asphaltenes and fine solids found in abundance in the bitumen composition hinder the oil/water/solid phase separation, particularly in the naphthenic froth treatment (NFT). This work systematically reviews the progress in the bitumen froth treatment in the oil sands surface mining process, influential factors in stabilizing/destabilizing the emulsions in these operations, the conventional emulsion treatment methods, and their effectiveness in the ultimate oil−water phase separation in the NFT process. The review attempts to summarize the up-to-date understanding of the origins of emulsion stability in the NFT and specify the research gaps in this area and also discusses overlooked technologies, methods, and future research perspectives which may be useful in implementing improved demulsification and fine solids removal strategies.

“…The centrifugal force also causes the formation of air core, which is one of the most complex flow structures inside a hydrocyclone [8] . The content of the air core comes from the atmosphere outside the hydrocyclone, or from the multiphase flow flowing through the hydrocyclones [9][10] . The previous researches have shown that the presence of air core affected the flow split ratio and the separation efficiency dramatically [11] , as well as the flow state of hydrocyclones [12] .…”

The evolution of air core is an important phenomenon in hydrocyclones, which is sensitive to the operating conditions. The morphology of the air core in a hydrocyclone is studied experimentally, using a high-speed video camera and a noise analyzer. Three stages are observed during the increase of flow rate from 300 to 2400 liters per hour, which could be separated by both the noise measurement and the stability of the air core. The flow rate is found to have a nonmonotonic effect on the diameter of the air core, leading to a peak diameter. The influence of the overflow and underflow on the underflow-to-throughput ratio and air flow patterns are also investigated. It is found that the underflow-to-throughput ratio and air flow patterns are sensitive to the valve openings of both outlets.
