Abstract: Systems and methods for using at least one sensor for monitoring a condition in a furnace are disclosed. The at least one sensor can be an optical fiber acoustic sensor. The at least one sensor can be coupled to at least one processor that can be configured to receive at least one measurement from the sensor, convert the at least one measurement into a digital format, and determine a condition associated with at least one burner based at least in part on the digital format. The digital format can be, for example, a sound waveform or a frequency spectrum.

Abstract: Embodiments described herein include an acoustic telemetry system for use with an apparatus configured to rotate. The acoustic telemetry system includes one or more sensor nodes and at least one receiver node. In at least one embodiment, the telemetry system also includes at least one hub node positioned on the apparatus. Each sensor node is attached to or embedded in the apparatus. Each sensor node obtains data related to one or more operating conditions of the apparatus and the environment surrounding the apparatus. The one or more sensor nodes encode and transmit the data to the hub node or the receiver node using ultrasonic acoustic waves. In at least one embodiment, the hub node transmits the data to the receiver node. The receiver node decodes the data and monitors the one or more operating conditions of the apparatus.

Abstract: A petroleum desalting process in which the role played by the oil/bulk-resolved-water interface in the dehydration of the stabilized emulsion which forms in the desalter is recognized. The desalting process is improved by introducing the demulsifier and chemical high voltage electrodes. Water droplets in the mixture coalesce and settle towards the bottom of the vessel. A stabilized emulsion layer formed from the oil and the water with additives into the water phase and/or injecting chemical additives directly in the vicinity of the water/oil interface. This improved methodology that makes the rapid and effective delivery of chemical demulsifiers to the rag layer and/or oil/bulk-resolved-water interface possible. In operation, the desalting is carried out by mixing a crude oil to be desalted with water and passing the mixture of oil and water to the desalter vessel. The mixture enters the desalting vessel in the form of an emulsified mixture which is then separated by application of an electric field between emulsion-stabilizing solids from the oil forms above the interface between the denser water layer and the supernatant oil layer. A chemical demulsifier is added to the water layer in the region of the stabilized emulsion layer and/or directly into the emulsion layer itself. The separated water is removed as effluent through a water outlet at the bottom of the vessel and desalted oil is removed from the oil layer through an oil outlet at the top of the vessel.

Abstract: A system for monitoring a line comprising a line, such as a mooring line, umbilical, pipeline, or riser. connected to an offshore structure including a control processor located on the offshore structure, a wireless network comprising a plurality of communication nodes positioned along the line, and a plurality of measurement devices embedded within the communication nodes. When the line is being monitored, the output of each of the measurement devices is in continuous wireless communication with the wireless network via at least one of the communication nodes positioned along the line and the wireless network is in continuous communication with the control processor.
