Abstract
Using a liquid in a liquid reservoir corresponding to an interior volume of a pig terminal, the pig terminal enabled for fluid communication with a gas pipeline, a first liquid pump enabled for fluid communication with both the liquid reservoir and the pig terminal removes a gas from the interior volume of the pig terminal in response to the first liquid pump causing the gas to be hydraulically displaced from the pig terminal by the liquid from the liquid reservoir, while a recovery line enabled for fluid communication with the pig terminal is enabled to remove the gas from the pig terminal.
Claims31
An apparatus for hydraulically displacing gas in gas pipelines, the apparatus comprising:
- a liquid reservoir enabled to store a liquid and corresponding to an interior volume of a pig terminal, the pig terminal enabled for fluid communication with a gas pipeline;
- a first liquid pump enabled for fluid communication with both the liquid reservoir and the pig terminal;
- and
- a recovery line enabled for fluid communication with the pig terminal, wherein the recovery line is further enabled to remove a gas from the interior volume of the pig terminal in response to the first liquid pump causing the gas to be hydraulically displaced from the pig terminal by the liquid from the liquid reservoir.
A method for hydraulic displacement, the method comprising:
- using a liquid in a liquid reservoir corresponding to an interior volume of a pig terminal, the pig terminal enabled for fluid communication with a gas pipeline, causing a first liquid pump enabled for fluid communication with both the liquid reservoir and the pig terminal to remove a gas from the interior volume of the pig terminal in response to the first liquid pump causing the gas to be hydraulically displaced from the pig terminal by the liquid from the liquid reservoir,
- wherein a recovery line enabled for fluid communication with the pig terminal is enabled to remove the gas from the pig terminal.
A controller for hydraulic displacement, the controller comprising:
- a processor enabled to access memory media storing instructions executable by the processor;
- and
- an input/output communications interface accessible to the processor and enabled to communicate with sensors and actuators and further enabled to provide a user interface for outputting information to and receiving commands from a user,
- wherein the instructions are executable by the processor for:
- using a liquid in a liquid reservoir corresponding to an interior volume of a pig terminal, the pig terminal enabled for fluid communication with a gas pipeline, causing a first liquid pump enabled for fluid communication with both the liquid reservoir and the pig terminal to remove a gas from the interior volume of the pig terminal in response to the first liquid pump causing the gas to be hydraulically displaced from the pig terminal by the liquid from the liquid reservoir,
- wherein a recovery line enabled for fluid communication with the pig terminal is enabled to remove the gas from the pig terminal.
