Abstract
Abstract This invention relates to an apparatus for desalting crude. The invention is in the form of an elongated horizontal vessel having semiwall partitions therein dividing the vessel into a mixing chamber, a settling chamber, and includes means of introducing fresh water for mixing with and washing the crude in the mixing chamber, means of subjecting the crude to electric fields in the downflow and final treating chambers to augment the separation water from the crude, and means for separately passing the desalted crude out one outlet opening and water having salt extracted from the crude out another outlet opening.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
51 words
An apparatus for desalting crude according to claim 1 wherein said vessel has a gas outlet opening communicating with the upper portion of said mixing chamber, said final treating chamber, and one of said quiescent chamber and said downflow treating chamber; and gas-collecting conduit means connecting with said gas outlet openings.
Claim 2
Dependent Claim
40 words
An apparatus for desalting crude according to claim 1 including: a plurality of paralleled, spaced-apart, perforated diverter plates supported within said mixing chamber, the diverter plates being inclined at a downward angle from said inlet end toward said first semiwall.
Claim 3
Dependent Claim
31 words
An apparatus for desalting crude according to claim 1 including: a horizontal perforated spreader plate supported within the lower portion of said quiescent chamber above the passageway under said first semiwall.
Claim 4
Dependent Claim
49 words
An apparatus for desalting crude according to claim 1 including: electric grid means supported within said final treating chamber, the electric grid means including horizontal spaced-apart grids having an electric field therebetween, the flow of fluid upwardly in said final treating chamber being thereby subjected to an electric field.
Claim 5
Dependent Claim
42 words
An apparatus for desalting crude according to claim 1 including: a horizontal perforated spreader plate supported within the upper portion of said downflow treating chamber above said electric grid means and below said fluid passageway over the top of said third semiwall.
Claim 6
Dependent Claim
34 words
An apparatus for desalting crude according to claim 1 including: a horizontal perforated spreader plate supported within the lower portion of said final treating chamber and above the fluid passageway under said fourth semiwall.
Claim 7
Dependent Claim
64 words
An apparatus for desalting crude according to claim 1 including: a horizontal perforated spreader plate in the upper portion of said final treating chamber between said fourth semiwall and said vessel outlet end, the perforated spreader providing a filter chamber in the upper portion of the final treating chamber, said oil outlet communicating with said filter chamber; and filter means within said filter chamber.
