Jumper lines with pumps
Example jumper lines with pumps are disclosed herein. An example includes a first pipe having fluid at a first pressure, a second pipe having fluid at a second pressure lower than the first pressure, and a jumper line including: a jumper pipe coupled between the first pipe and the second pipe that bypasses a device between the first pipe and the second pipe; a valve coupled to the jumper pipe, the valve to open to enable the fluid at the first pressure to evacuate to the second pipe until the first pipe is equalized with the second pipe; and a pump coupled to the jumper pipe, the pump to, when activated, move at least a portion of the fluid from the first pipe to the second pipe.
1 . A system comprising:
a first pipe having natural gas at a first pressure;
a second pipe having natural gas at a second pressure lower than the first pressure;
a jumper line including:
a jumper pipe coupled between the first pipe and the second pipe that bypasses a device between the first pipe and the second pipe;
a valve coupled to the jumper pipe, the valve to open to enable the natural gas at the first pressure to evacuate to the second pipe until the first pipe is equalized with the second pipe; and
a pneumatic pump coupled to the jumper pipe, the pneumatic pump having a driving side and a driven side, the driving side of the pneumatic pump to, when activated, drive the driven side of the pneumatic pump to move at least a portion of the natural gas from the first pipe to the second pipe; and
a third pipe to supply high pressure natural gas to an inlet of the driving side of the pneumatic pump to drive the pneumatic pump, and wherein an outlet of the driving side of the pneumatic pump is vented to the second pipe such that the high pressure natural gas used to drive the pneumatic pump is vented to the second pipe.
2 . The system of claim 1 , wherein the device includes at least one of a valve, a compressor, or a regulator.
3 . The system of claim 1 , further including a fourth pipe fluidly coupled between the driving side of the pneumatic pump and the jumper pipe downstream of the driven side of the pneumatic pump.
4 . A method comprising:
closing a first valve or maintaining the first valve in a closed position, the first valve coupled between a first pipe having natural gas at a first pressure and a second pipe having natural gas at a second pressure lower than the first pressure;
opening a second valve of a jumper line, the jumper line including a jumper pipe fluidly coupled between the first pipe and the second pipe that bypasses the first valve between the first pipe and the second pipe, wherein opening the second valve enables the natural gas at the first pressure to flow from the first pipe to the second pipe until the first pipe is equalized with the second pipe; and
activating a pneumatic pump coupled to the jumper pipe to pump at least a portion of the natural gas from the first pipe to the second pipe, wherein the pneumatic pump is driven by high pressure natural gas from a third pipe, and wherein the pneumatic pump is fluidly coupled to the second pipe by a fourth pipe such that the high pressure natural gas used to drive the pneumatic pump is routed to the second pipe.
5 . The method of claim 4 , further including:
determining a pressure in the first pipe; and
when the pressure in the first pipe reaches a target pressure, deactivating the pump.
6 . The method of claim 4 , further including at least one of closing the second valve or disconnecting the jumper line from the first and second pipes.
7 . A system comprising:
a pipeline to supply fluid at a first pressure;
a compression station having one or more compressors to increase the fluid from the pipeline to a second pressure higher than the first pressure;
a facility to receive and use the fluid at the second pressure;
a jumper line fluidly coupled between the facility and the pipeline, the jumper line including a valve and a pump, the pump separate from the one or more compressors of the compression station; and
control circuitry to:
cause the valve to open to enable the fluid in the facility to evacuate to the pipeline until the facility is equalized with the pipeline; and
cause the pump to activate to move at least a portion of the fluid from the facility to the pipeline.
8 . The system of claim 7 , wherein the valve is a first valve, further including a second valve upstream of the facility, the control circuitry to cause the second valve to close prior to opening the first valve of the jumper line.
9 . The system of claim 7 , wherein the fluid is natural gas.
10 . The system of claim 9 , wherein the pump is a pneumatic pump to be driven by high pressure natural gas.
11 . The system of claim 10 , wherein the pneumatic pump has a driving side to receive the high pressure natural gas, and wherein an outlet of the driving side of the pneumatic pump is vented to the pipeline.
