Title:
CRUDE OIL DEWATERING APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/011817
Kind Code:
A1
Abstract:
An electric field acting assembly (300) for treating crude oil, it is arranged in
line with a pipeline (100), and it includes a cavity (301) with an oil inlet used to
connect the upstream pipeline (100) for conducting crude oil and an oil outlet used
to convey the crude oil to downstream; an electric field acting area arranged between
the oil inlet and the oil outlet for treating the crude oil; a voltage supply source
(200) used to provide voltage for the electric field acting assembly (300); wherein
the size ratio of the cavity's cross section vertical to the flow direction
of the crude oil to the pipeline's is 1-3. The electric field acting assembly
(300) can be applied to a dewatering unit for treating crude oil and a crude oil
dewatering system comprising the dewatering unit. By using the electric field
acting assembly (300), the dewatering and desalting equipment may be more simple
and compact in structure, and the dehydration rate and efficiency can be increased.
