    摘要： A method to remove coke from a coker drum is disclosed. The method includes the steps of impinging fluid from a fluid jet on the inside surface of the coker and then determining the vibration signal of the coker drum. The signal is then transformed to determine the amplitude versus frequency by a Fourier Transform of the vibration signal. The amplitude change of the vibration signal as it goes through a maximum, determines when the coke layer has been cut. The fluid jet is lowered into a new layer of coke.

    摘要： The present invention is a non-intrusive method to determine the fluid level in a vessel. In a preferred embodiment, the vessel is a delayed coker drum in a refinery. Waves are generated in the vessel from an outside source. For wall vibration generated in the frequency range of 1-20,000 Hz, accelerometers on the exterior wall of the vessel measures the attenuation of the vibration modes of the vessel. The fluid level can related to the attenuation of the vibration mode. For wall vibration generated in the ultrasonic range, the wave traveling in the vessel wall are guided waves. The guided wave will leak energy into the fluid inside the vessel and will attenuate depending on the fluid level. Ultrasonic receivers on the outside of the vessel measure the attenuation. The fluid level can be related attenuation of the ultrasonic waves.

    摘要： Provided are systems and methods for in-situ zonal assessment of multiphase fluid flow in one or more production zones of a production well, including for at least one production zone sensing one or more fluid flow parameters via at least one sensor disposed in a production zone; at least one sensor communications node being in electrical communication with an associated sensor, the at least one sensor communications node positioned along a tubular body in the production zone proximate an associated at least one sensor, and receiving signals from the associated at least one sensor; sending the acoustic signals from the at least one sensor communications node to a receiver at a surface via a series of intermediate communications nodes, node-to-node, the signals being indicative of one or more fluid flow parameters, the series of intermediate communications nodes being spaced along the tubular and configured to transmit acoustic waves; assessing one or more fluid flow parameters for the one or more production zones in response to signals received from a topside communications node.
