Abstract
A system, apparatus, and method for improving performance of a pressurized system that attenuates pulsations in gases having varying acoustic velocities.
Claims17
A natural gas pumping system that attenuates pulsations in gases having varying acoustic velocities, comprising:
- a reciprocating compressor that receives gases having varying acoustic velocities including:
- a first cylinder having:
- an inlet through which natural gas having varying acoustic velocities is received;
- and
- an outlet through which the natural gas is discharged;
- a second cylinder having:
- an inlet through which the natural gas having varying acoustic velocities is received;
- and
- an outlet through which the natural gas is discharged;
- a first conduit having a first end in fluid communication with the outlet of the first cylinder and a second end in fluid communication with a junction;
- and
- a second conduit having a first end in fluid communication with the outlet of the second cylinder and a second end in fluid communication with the junction, thereby attenuating pulsations in the varying acoustic velocity gas.

A method of reducing pressure variations in a natural gas pumping system that attenuates pulsations in gases having varying acoustic velocities, the method comprising:
- combining natural gas that has varying acoustic velocities flowing from a first reciprocating cylinder having a first periodic pressure fluctuation characteristic operating in a first phase with natural gas that has varying acoustic velocities flowing from a second reciprocating cylinder having a second periodic pressure fluctuation characteristic operating in a second phase when the first periodic pressure fluctuation characteristic is out of phase with the second periodic pressure fluctuation characteristic.
A pressure wave attenuation system that attenuates pulsations in fluids
- having varying acoustic velocities, comprising:
- one or more reciprocating compressors together comprising a first cylinder, a second cylinder, a third cylinder, and a fourth cylinder, each cylinder pumping natural gas that periodically has a varying acoustic velocity;
- a first header in fluid communication with the first cylinder and a first junction;
- a second header in fluid communication with the second cylinder and the first junction such that a pressure wave propagating in the fluid having a varying acoustic velocity flowing through the first header and a pressure wave propagating in the fluid having a varying acoustic velocity flowing through the second header are attenuated when the fluid flowing from the first header and the fluid flowing through the second header combine at the first junction;
- a third header in fluid communication with the third cylinder and a second junction;
- a fourth header in fluid communication with the fourth cylinder and the second junction such that a pressure wave propagating in the fluid having a varying acoustic velocity flowing through the third header and a pressure wave propagating in the fluid having a varying acoustic velocity flowing through the fourth header are attenuated when the fluid having a varying acoustic velocity flowing from the third header and the fluid having a varying acoustic velocity flowing through the fourth header combine at the second junction;
- a first branch line in fluid communication with the first junction and a third junction;
- and
- a second branch line in fluid communication with the second junction and the third junction, the length of the second branch line differing from the length of the first branch line such that a pressure wave propagating in the fluid in the first branch line and a pressure wave propagating in the fluid in the second branch line are attenuated when the fluid having a varying acoustic velocity flows from the first and second branch lines and combines at the third junction.
