Cannon Artes, in collaboration with the University of Salerno, developed a semi-empirical model for the prediction of solids removal from water, as a function of operative conditions; model parameters are based on the results of experimental tests conducted on a pilot-scale plant.

Cannon Artes Desander

Solid-liquid (S-L) hydrocyclone allows a continuous and efficient separation of fine particles, mainly sand and other solids, with dimensions in the range of 5-100 μm. This technology provides the best fitting solid removal solution in industrial processes and waste streams when a very effective separation is required, such as petrochemicals processing, mining, and the food industry.

One of the main applications of hydrocyclone desanding is produced water treatment in the oil&gas upstream sector. In this case, desanding hydrocyclones are installed at the outlet of three-phase separators with the aim to protect the downstream equipment such as deoiling hydrocyclone, CPI, flotator, and media filters.

Desanding can be used also in order to avoid solids accumulation in the reinjection water to achieve the maximum allowable solids concentration of 5 ppm.
