INSTALLATION FOR FLOTATION PURIFICATION OF SEWAGE FROM CUT OIL AND OIL PRODUCTS Russian patent published in 2004 - IPC

FIELD: oil producing and oil refining and a petrochemical industries.

SUBSTANCE: the invention presents an installation for floatation purification of sewage from cut oil and oil products. It is dealt with The invention falls into oil producing, oil refining and a petrochemical industries, in particular with the equipment intended for purification of sewage, containing petroleum or products of its processing, and also with flooding of seams and maintenance of a seam pressure at development of oil deposits. The installation includes two located in one housing sections - a mass-exchanging and a gas-separating sections, an inlet system of recirculating water with pumps and the choke bean elements, a system of water seals and gas-bypassing lines between the mass-exchanging and a gas-separating sections and it additionally has at least one mass-exchanging and one gas-separating sections. Each mass-exchanging section in a zone of a gas phase is connected to the recycling pump. The system of feeding of the recirculating water in the mass-exchanging section is made at least bimodal. The choke bean elements are located uniformly at each level within the volume the mass-exchanging section. The choke bean elements of the upper level are mounted with a capability of their location in the gas phase on the given distance from the water - gas interphase boundary. The choke bean elements of the lower level or levels are mounted with a capability of their location immersed in the being cleaned water and supplied with hydrodynamic silencers. The technical result is upgrading of quality of water purification and reduction of material inputs.

EFFECT: the invention allows to improve quality of water purification and to reduce materials inputs.
