Description
Technical field
The present invention relates to the device of direct electric dehydration under crude water after a kind of ocean engineering field pre-separation, particularly relate to
And a kind of subsea production system inclines the online apparatus for electrodewatering of tubular type row-column electrode formation.
Background technology
At present, the typical oil vapor treatment auxiliary facility in domestic and international offshore platform and land oil recovery factory and chemical plant is " oil
Well produces liquid → standpipe → offshore platform manifold → three phase separator → secondary heater → heat chemistry separator → booster pump → electricity
Dehydrator ", wherein electrical oil dewatering water technology mainly use the electric dehydrator of conventional canister, using electric field to crude oil demulsification,
And the particle water in oil is implemented to separate sedimentation, whole electrical oil dewatering water treatment facilities are bulky and disengaging time is more long；This
Outward, the flow before electrical oil dewatering water process is complex, collects the excess losses such as electric energy and heat energy in defeated and separating treatment tight
Weight, has been significantly greatly increased the heat energy supply of the electric load and heat stations facility of offshore platform power station facility.
The need in order to meet marine deepwater and marginal oil field, based on to appropriate turbulent flow can promote dispersion
The full appreciation of the problems such as collision of phase particle water, coalescence, researcher's breakthrough of American-European some oil big countries was conventional former in recent years
The inertial thinking pattern of oil dehydrator structure design, it is proposed that particle water coalescence is grown up and gravitational settling two processes are separated
