Abstract
Based on the established regularities of organic emulsions phase separation processes by the method of ultra flocculation and turbulent micro flotation, a mobile flotation unit designed to purify rinsing water formed during removal of oil and oil contaminants from the surface of aboveground and underground tanks of sea vessels fuel and oil tanks, railroads and truck tanks, manholes of industrial and municipal sewerage is worked out. The containers were washed with an aqueous solution of GIPCH-3 A (a mixture of hydrochlorides of primary aliphatic amines), which is an effective flotation collector of fine-emulsified petroleum products. Purification of spent detergent solution from petroleum products was carried out in a pneumatic flotation column with pretreatment in a flocculent using cationic flocculent and application of a certain medium velocity gradient. The introduction of this installation will allow the implementation of the washing process in the mode of recycled water supply using a small volume of washing solution and efficiently utilizing washed oil products.
