INSTALLATION TO SEPARATE WATER AND MECHANICAL IMPURITIES FROM VISCOUS PETROLEUM PRODUCTS Russian patent published in 2008 - IPC B01D17/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to gravity effect units used to separate unmixable liquids and may be used to separate water and mechanical impurities from viscous petroleum products the installation consists of the tank with a cover incorporating a neck, a watery petroleum product inlet branch pipe, a vertical pipe with a pacifier. The tank accommodates the separated water drain branch pipe, dewatered petroleum product branch pipe and that for removal of mechanical impurities. A heat exchanger made up of separate section is arranged outside the tank all along its perimeter. Every section is composed of horizontal pipes communicating with the manifolds. The sections communicate via angular branch pipes. The heat exchanger end face section incorporate heat carrier inlet and outlet branch pipes. The heat exchanger is covered with demountable composite heat insulating casing the inner surface of which has horizontal and vertical grooves accommodating pipes and manifolds. The tank has a vertical partition forming the separated water accumulation space and arranged with a gap between the bottom. The other vertical partitions are fixed on tank 1 side walls staggered with a gap relative to the opposite side wall.

EFFECT: wider range petroleum products for separation water and mechanical impurities from them.
