Abstract
Abstract A pipeline carrying gas and liquid, wherein the liquid may form slugs filling the whole cross-section, has an expansion chamber 4 wherein the liquid and gas are separated, led through separate outlets 13, 7 and recombined to form a homogeneous mixture. The outlets have respective restrictions 15, 9. In Fig. 2 a perforate section of pipeline extends through the chamber, to enable spherical pigs to be propelled therethrough for cleaning purposes. In Fig. 3 the two flows recombine inside the chamber. <IMAGE>

Claims Analysis
Total Claims: 40
Claim 1
Independent Claim
66 words
An apparatus for regulating the flow of a multi-phase flow of fluid through a pipeline, said apparatus being incorporated in the pipeline and comprising an inlet adapted to receive the multi-phase flow passing through the pipeline, said inlet communicating with a separation vessel of enlarged cross-section relative to the pipeline, and at least one outlet from the separation vessel connected to the continuation of the pipeline.
Claim 2
Independent Claim
66 words
An apparatus for regulating the flow of a multi-phase flow of fluid through a pipeline, said apparatus being incorporated in the pipeline and comprising an inlet adapted to receive the multi-phase flow passing through the pipeline, said inlet communicating with a separation vessel of enlarged cross-section relative to the pipeline, and at least one outlet from the separation vessel connected to the continuation of the pipeline.
Claim 3
Independent Claim
132 words
An apparatus to be incorporated in a pipeline adapted to carry a multi-phase flow to regulate that flow, said apparatus comprising an inlet adapted to receive the flow passing through the pipeline, said inlet communicating with the interior of a separation vessel having an enlarged internal cross-section relative to pipeline, said separation vessel having at least a first outlet located at or adjacent the top of the vessel to permit a gaseous phase to leave the vessel, and having a second outlet at a lower position adapted to permit the egress of a liquid phase from the vessel, the outlets each being connected to a combining means where the flows from the outlets are re-combined, the apparatus having an outlet through which the re-combined flows may pass, again entering the main pipeline.
Claim 4
Independent Claim
132 words
An apparatus to be incorporated in a pipeline adapted to carry a multi-phase flow to regulate that flow, said apparatus comprising an inlet adapted to receive the flow passing through the pipeline, said inlet communicating with the interior of a separation vessel having an enlarged internal cross-section relative to pipeline, said separation vessel having at least a first outlet located at or adjacent the top of the vessel to permit a gaseous phase to leave the vessel, and having a second outlet at a lower position adapted to permit the egress of a liquid phase from the vessel, the outlets each being connected to a combining means where the flows from the outlets are re-combined, the apparatus having an outlet through which the re-combined flows may pass, again entering the main pipeline.

An apparatus according to Claim 8 wherein at least one said valve is remotely controllable.
Claim 12
Dependent Claim
28 words
An apparatus according to Claim 5 or Claim 6 wherein the or each constriction consists of a projection formed on the interior of a conduit defining a venturi.
Claim 13
Independent Claim
21 words
An apparatus according to any one of the
Claims 2 to 10 wherein the said combining means comprises a T connector.
Claim 14
Independent Claim
42 words
An apparatus according to any one of Claims 2 to 11 wherein the second outlet comprises an outlet located in the bottom of the separator vessel, the first outlet and the second outlet being connected by respective conduits to said combining means.
Claim 15
Independent Claim
71 words
An apparatus according to any one of Claims 2 to 11 wherein the first outlet is located within the separation vessel adjacent the top thereof and the second outlet is located within the separation vessel adjacent the bottom thereof, the two outlets being interconnected by a conduit within the separation vessel, which constitutes the combining means, a further conduit, carrying the combined flow, passing through an outlet of the separation vessel.
Claim 16
Independent Claim
51 words
An apparatus according to any one of Claims 2 to 11 wherein the said inlet to the separation vessel comprises part of a perforated linear pipe which extends through the separation vessel to an outlet of the separation vessel which is axially aligned with the inlet, and comprising said second outlet.
Claim 17
Independent Claim
62 words
A method of regulating a multi-phase flow in a pipeline, said method comprising the steps of causing the flow to pass through a length of the pipeline of predetermined cross-sectional area, subsequently causing the flow to pass into an enlarged cross-sectional area separation vessel, and subsequently withdrawing the two separated phases of the flow, from that separation vessel, as a re-combined flow.
