Description
Technical field
The utility model relates to a kind of oily-water seperating equipment, especially relates to a kind of offshore oilfield production fluid treatment unit of hydraulic vortex-physical excitation-modification bamboo charcoal filtering integral.
Background technology
At present, along with China's oil and Natural Gas Geology reserves start to increase substantially, crude production rate continues to rise, and the cost of oil production is also in continuous rising.For reducing production cost, the treatment scheme of oilfield produced fluid need be simplified, reducing the investment of offshore production facility.The oil phase of offshore oilfield and aqueous phase treatment scheme are merged into a comprehensive treatment scheme, can reduce costs, the exploitation for offshore marginal oilfield is a kind of technique means preferably.
Degassed flotation technology combines with rotating centrifugal isolation technique by air supporting eddy flow combination technique, and the treatment facility of development both at home and abroad at present mainly contains the compact type air-floating apparatus of OpusMaxin company, the DeepSweep of Cyclotech company
tMthe movable type that the Crude-Sep device of device, CETCO company, the CFU device of Epcon company and China University Of Petroleum Beijing develop sprays air supporting cyclone separation device etc.
From 2000 to 2008, CFU device was used to Brazilian Garoupa oil field, the BrageTroll oil field of Norway, the AlbaNorthern oil field etc. of Britain, and day process wastewater flow rate can reach 31.8 ten thousand m
3/ d.Wherein, Brage oil field, waste treatment capacity reaches 200m
3/ h, the waste water oleaginousness after process is lower than 20mg/L.
Physical excitation utilizes physical means to impose vigorous physical to oilfield produced fluid to agitate energy dissipating, the most of Sweet natural gas etc. be dissolved in production fluid is separated out in a short period of time simultaneously, and then in water, produce a large amount of micro-bubbles, from water, elaioleucite, suspended particle etc. in meeting Contact-sorption water in the process of the water surface is floated at small bubbles, and it is carried float up to the water surface, greatly optimize the oil removing purification process of oilfield produced fluid.
It is the specific surface area that utilizes carbonaceous itself huge and flourishing pore texture that modification bamboo charcoal filters, absorption and strainability high, can most of dissolving oil and suspended substance in planar water effectively, thus dissolving oil in removal water and suspended substance.
In recent years, the domestic invention for cyclone air-flotation device is also more, and traditional hydraulic cyclone and filtration unit are two different unit, and not containing physical excitation device, floor space is large, and processing efficiency is relatively low.Consider offshore platform limited space, technical process conveniently can cause that the treatment unit floor space of offshore oilfield production fluid is large, treatment scheme is many, increases investment and processing cost.At present, the research and development of offshore oil water separation device are just towards compact and efficient future development.
