Abstract

The invention discloses tubular oil-water cyclone separation equipment. The equipment mainly comprises a liquid inlet pipe, a swirler, a separating cavity and a liquid discharge pipe. The overall equipment adopts a tubular structure, and space occupied by the cyclone separation equipment can be saved to a larger extent; a rotary flow field is generated by the aid of streamline blades, the inlet pressure and the operating pressure are far smaller than those of a conventional tangential inlet type hydrocyclone, and the treatment capability is far higher than that of the conventional tangential inlet type hydrocyclone; with the adoption of an axial flow tubular structure, the equipment has the advantages of compact structure, high treatment capacity, small resistance loss, high oil-water separation efficiency and the like, can be used for the oil-water separation process in the petroleum and chemical industry and is particularly suitable for an offshore platform. Multitube skid-mounting is easy to realize, and the problem that the conventional tangential inlet type hydrocyclone occupies large space is solved.

Description

technical field [0001] The invention relates to a fluid separation technology, in particular to a tubular oil-water cyclone separation device, which is suitable for the oil-water separation process in petroleum and chemical industries. Background technique [0002] At present, most oil fields in China are in the middle and late stage of exploitation, and the water content in the oil well production fluid gradually increases, and some oil fields often exceed 90% (a small number of oil wells even reach 95%). Therefore, whether it is in the production process of offshore oilfields or onshore oilfields, a large amount of oil-water mixture will be produced, and the oil-water separation process occupies a very important position. Traditional dehydration treatment facilities based on gravity separation generally have shortcomings such as low efficiency, large footprint, and long residence time, making it difficult to cope with the situation of rising moisture content in the middle ...
