Abstract
Abstract A device in connection with a separator for separation of a multiphase fluid, including a preferably cylindrical container ( 1 ) with an inlet ( 2 ), a first outlet ( 3 ) for liquid with a higher gravity (for example water), a second outlet ( 4 ) for liquid with a lower gravity (for example oil) and a third outlet ( 5 ) for gas. A pipe separator ( 6 ) is connected to the inlet ( 2 ) of the container ( 1 ). The pipe separator ( 6 ) constitutes a continuation of a supply pipe ( 7 ) for supplying the fluid to be separated and extends partially into the container ( 1 ).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A device for separating of a multiphase fluid, the device comprising: a substantially horizontally oriented cylindrical container having an inlet at one end, a first outlet for liquid with a higher specific gravity, a second outlet for liquid with a lower specific gravity relative to the first liquid, and a third outlet for gas; a substantially horizontally oriented pipe separator disposed upstream of the container and connected to the inlet of the container; and a supply pipe disposed upstream of the pipe separator for supplying the multiphase fluid to the pipe separator, wherein the supply pipe is connected to an inlet end of the pipe separator wherein the pipe separator has a greater diameter than the supply pipe and the container has a greater diameter than the pipe separator.
Claim 2
Independent Claim
129 words
A device for separating of a multiphase fluid, the device comprising: a substantially horizontally oriented cylindrical container having an inlet at one end, a first outlet for liquid with a higher specific gravity, a second outlet for liquid with a lower specific gravity relative to the first liquid, and a third outlet for gas; a substantially horizontally oriented pipe separator disposed upstream of the container and connected to the inlet of the container; and a supply pipe disposed upstream of the pipe separator for supplying the multiphase fluid to the pipe separator, wherein the supply pipe is connected to an inlet end of the pipe separator wherein the pipe separator has a greater diameter than the supply pipe and the container has a greater diameter than the pipe separator.
Claim 3
Dependent Claim
49 words
The device as claimed in claim 1 , further comprising a source of multiphase fluid including oil, water and gas, and the container inlet is arranged, for water-continuous inflow, at a level in the container that is equivalent to the level of an expected water phase in the container.
Claim 4
Dependent Claim
47 words
The device as claimed in claim 1 , further comprising a source of multiphase fluid including oil, water and gas, and the container inlet is arranged, for oil-continuous inflow, at a level in the container equivalent to the level of an expected oil phase in the container.
Claim 5
Dependent Claim
17 words
The device as claimed in claim 1 , wherein the pipe separator extends partially into the container.
Claim 6
Dependent Claim
39 words
The device as claimed in claim 4 , wherein the container includes a partition and the first outlet is located on one side of the partition, and the second outlet is located on a second side of the partition.
