摘要： A method for operating a pipeline system includes obtaining sensor data of a gas in the pipeline system from sensors of a sensing unit. The method also includes performing a real-time and closed loop control scheme using the sensor data and a material model of the gas to determine one or more control decisions. The method also includes operating one or more controllable pipeline elements to adjust a temperature, a pressure, a flow rate, or a composition of the gas according to the one or more control decisions.

摘要： Retractable quills for use with a pipe or vessel containing a fluid, and methods of operation thereof, are described. The retractable quill has a cylinder and a hollow rod slidably disposed within the cylinder, the hollow rod having a first end configured to be inserted into the pipe or vessel in fluid communication with the fluid. The retractable quill also has a drive system configured to move the hollow rod within the cylinder between an extended position where the first end of the hollow rod is inserted into the pipe or vessel and within the fluid and a retracted position where the first end of the hollow rod is outside of the pipe or vessel. The retractable quill may be configured to maintain a positive pressure seal when the hollow rod is moved between the extended position and the retracted position.

摘要： A combined chemical injection and mixing system including an injection stream pipe, a target pipe disposed within the injection stream pipe, and a plurality of injection quills is described. The injection stream pipe encloses the plurality of injection quills, and the plurality of injection quills each independently includes a quill check valve and a quill flange. A method for mixing at least one chemical in a pipeline is also described. The method includes providing a chemical injection and mixing system configured to a pipeline, forming a pipeline treatment system, providing a fluid flow in the pipeline treatment system, injecting at least one chemical via the plurality of injection quills, and mixing the at least one injected chemical in a mixing zone of the chemical injection and mixing system, thereby mixing the at least one injected chemical in the fluid flow.

摘要： A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.

摘要： The embodiments of the present disclosure provide methods and Internet of Things systems for controlling automatic odorization of smart gas device management. The method may include obtaining gas data of a first gas sample at a first position of a smart gas pipeline network based on a sampling device; odorizing at a second position of a smart gas pipeline network based on odorization parameters through an odorization device; obtaining inspection data of a second gas sample at a third position of the smart gas pipeline network based on an inspection device; updating the odorization parameters based on the inspection data through a device parameter remote management module; and odorizing at the second position of the smart gas pipeline network based on the updated odorization parameters through the odorization device.

摘要： An odorization system is provided that introduces foul-smelling odorant into a natural gas pipeline in order to make gas leaks more easily detectable. The system improves upon prior art odorization systems by using a pumpless mechanism driven by differential pressures. The elimination of pumps from the system reduces the likelihood of system failure and further reduces the likelihood that odorant leaks to atmosphere.

摘要： A polymer composition has been developed that provides low viscosity oil-in-water polymer emulsions that release the polymer in the emulsion at a faster rate and without an additional surfactant when the emulsion is added to a hydrocarbon stream. Use of a temperature-sensitive emulsifying surfactant facilitates inversion of the oil-in-water polymer emulsion when applied to a hydrocarbon composition at a temperature sufficiently high to destabilize the emulsion. These compositions are particularly useful as drag reducers for delivery to a subsea flowline via an umbilical line.

摘要： Method and system for clearing a pipe system from its contents, the pipe having a proximal end and a distal end, the method including providing an air supply to the pipe system at the proximal end by applying an air pressure decreasing from an initial pressure as the bulk of the pipe contents get discharged gradually at the distal end for obtaining a contents flow in the pipe system. The method further includes determining a volume of air supplied to the pipe system by the air supply, determining an estimated contents travel speed from the volume of the air supplied to the pipe and regulating the air supply to the proximal end of the pipe for obtaining a predetermined pipe contents travel speed using the estimated contents travel speed.
