Abstract: A system, including: a subsea separation system that separates sales and non-sales fluids, wherein the subsea separation system includes a fluid polishing system; a seal-less pump that boosts production fluid pressure; and a water quality monitoring system, including an oil-in-water sensor and a solids-in-water sensor, that monitors a fluid discharged from the subsea separation system.

Abstract: The present techniques are directed to a pipeline transporting a production fluid including hydrocarbon. An optical fiber is disposed along a length of the pipeline. A control system determines a predicted operating temperature based on pressure and flow rate of the production fluid in the pipeline. The control system determines a measured temperature along the pipeline using the optical fiber. The control system detects and locates a temperature anomaly by comparing the measured temperature of the pipeline to the predicted operating temperature.

Abstract: The present techniques are directed to systems and methods for forming a pipe-conforming structure.

Abstract: System and method for detecting a leak in a pipeline with a sensing cable including an optical fiber sensor array aligned with a heating element. At least one heat pulse is propagated through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and fluid exposed to the sensing cable. A temperature profile of the sensing cable corresponding to the heat pulse at each of a plurality of sensor locations on the optical fiber sensor array is measured over time. A leak in a pipeline is detected by determining one or more properties of the fluid exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto.

Abstract: The present invention describes the synthesis of solvent soluble copolymers containing multiple unsaturations. These copolymers contain reactive vinyl groups, which can be further reacted in a second stage polymerization. The process involves copolymerization of a vinyl monomer with an inclusion complex of a monomer having multiple unsaturations and a cyclic macromolecular compound to yield soluble polymers. These polymers may be cast into films, membranes or may be converted in micro or nanoparticles and then crosslinked in a second step polymerization.

The lipid or a blend of lipids, are used in combination with the pH dependent polymer where the said polymer is acid soluble or swellable The process for the preparation of taste masked pharmaceutical compositions of the bitter drugs comprising the said lipid-polymer compositions are disclosed. The concomitant use of the acid soluble polymer, which remains collapsed at the pH of saliva, inhibits the release of drug at that pH and hence they further help in bitterness inhibition. The said compositions deliver substantial amount of the bitter drug immediately at the gastric pH with improved palatability.
