A method of forming a drag reducing polymer formulation. The method begins by forming a drag reducing polymer. A hydrocarbon additive is then incorporated with the drag reducing polymer to form a drag reducing polymer formulation. The drag reducing polymer formulation is then used as a drag reducer in hydrocarbon pipelines.

The embodiments of the present disclosure provide method and Internet of Things system for determining odorization parameters 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, odorizing at a second position of the smart gas pipeline network based on the odorization parameters, obtaining inspection data of a second gas sample at a third position of the smart gas pipeline network, and sending the inspection data to the smart gas pipeline network device parameter management sub-platform for analysis and processing, obtaining a target odorization concentration, and determining target odorization parameters, updating the odorization parameters based on the target odorization parameters, and send updated odorization parameters to the smart gas data center, and odorizing, based on the updated odorization parameters, at the second position of the smart gas pipeline network.

The present invention generally relates to methods and hydrate inhibitor compositions for inhibiting the formation of hydrates in a fluid comprising gas and water. More specifically, the method comprises contacting a hydrate inhibitor composition to a fluid. The hydrate inhibitor composition comprises a nonpolar solvent; a polar solvent; and a polymer, an oligomer, a dendrimer, or an acid or salt thereof.

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.
