摘要： Online measurement of dispersed oil phase in produced water can be implemented a method on-site of a flowline transporting a fluid that includes dispersed oil in water. A sample of the fluid flowed through the flowline is obtained. The sample includes the oil phase and the water phase. The sample is combined with a chemical element that can separate the oil phase in the sample from the water phase in the sample. The separated oil phase and the chemical element are transferred into a measurement cell. The chemical element is removed from the measurement cell. After the chemical element is removed from the measurement cell, a quantity of the oil phase in the sample in the measurement cell is determined by a capacitive measurement technique. The determined quantity of the oil phase in the sample is provided.

摘要： Apparatuses and methods of measuring a hydrogen diffusivity of a metal structure including during operation of the metal structure, are provided. A hydrogen charging surface is provided at a first location on an external surface of the structure. In addition, a hydrogen oxidation surface is provided at a second location adjacent to the first location on the external surface of the structure. Hydrogen flux is generated and directed into the metal surface at the charging surface. At least a portion of the hydrogen flux generated by the charging surface is diverted back toward the surface. A transient of the diverted hydrogen fluxes measured, and this measurement is used to determine the hydrogen diffusivity of the metal structure in service.

摘要： Separation apparatuses for the separation of a mixture of two fluids, such as a water-in-oil emulsion, via electrocoalescence, are provided. A separation apparatus may include a series of flow conditioners each having a different permittivity, such that the flow conditioner having a permittivity that is similar or equal to the permittivity of the flowing medium is selected. Another separation apparatus may include a flow conditioner having a frequency-dependent permittivity, such that the frequency of the electric field generated is selected so that the permittivity of the flow conditioner is as similar as possible to or equal to the permittivity of the flowing medium. Another separation apparatus may include a replaceable flow conditioner that may be replaced with a flow conditioner having a permittivity that is as similar to or equal to the permittivity of the flowing medium.
