摘要： Simultaneous determination of general corrosion and localized corrosion rate measurements is achieved with polarization applied by the electrodes themselves rather than externally applied polarization. Two or more working electrodes may be galvanically coupled. A localized pitting corrosion event on one of the electrodes will lead to a potential transient. The area within the potential transient is measured with the baseline being the initial starting potential. This gives localized corrosion as a function of time. The relationship Rp=ΔV/ΔI is calculated, where Rp is the polarization resistance of the working electrodes and is a measure of generalized corrosion rate.

摘要： Aluminum carboxylate drag reducing agents are described herein. These materials are useful to reduce drag in hydrocarbon fluids and multiphase fluids of hydrocarbon(s) and water. No injection probes or other special equipment is expected to be required to introduce the drag reducing agent into the liquid stream. The drag reducing additives of the invention are not subject to shear degradation and do not cause undesirable changes in the emulsion or fluid quality of the fluid being treated, or undesirable foaming. In one non-limiting embodiment, an aluminum monocarboxylate is reacted with at least one carboxylic acid in situ. In another non-limiting embodiment, the aluminum carboxylate is introduced as a dispersion in a solvent such as paraffin oil. The drag reducing additives include aluminum dicarboxylates such as aluminum dioctoate, aluminum distearate, aluminum octoateoleate, aluminum octoatestearate, aluminum stearateoleate, hydroxyaluminum bis(2-ethylhexanoate) and mixtures thereof.

摘要： A localized corrosion monitoring (LCM) device is modified to obtain polarization resistance (Rp) from electrical resistance of a probe having a strip of metal under investigation (test electrode), a reference electrode and a temperature sensor (e.g. thermocouple). This configuration allows the probe to be used in areas where only a thin film of conductive fluid is available or required to provide potential monitoring. Thus, the applicability of the LCM technique is broadened. All the above devices are expected to be configured in one item of equipment, except for the probe which may be remotely located from the rest of the equipment.

摘要： An electrochemical noise method, apparatus and system may be used to estimate and/or calculate parameters of interest related to corrosion rates of an electrically conductive article. The apparatus involves a working electrode (having substantially the same composition of the electrically conductive article), a reference electrode, and a counter electrode in an environment of interest. The working electrode is placed under potentiostatic control. A current transient between the working electrode and the counter electrode is measured. The working electrode is switched to open potential. A potential transient is measured over the duration of a localized corrosion event. The localized corrosion may then be calculated based on the measured potential transient and the current transient.

摘要： Solids deposition in a gas environment, such as a gas transmission line or pipeline are measured using metal-coated quartz crystal microbalance (QCM) in a QCM probe within a high pressure gas chamber in the gas environment. The metal coated on the QCM may be iron, iron alloys and/or iron oxide. The weight measurements are conducted at a constant (ΔT) or controlled (T=f(t)) temperature between the high pressure gas chamber and the QCM probe. The weight gain during a CE cycle is associated with the solids formation rate.

摘要： A method for predicting scale deposition in a general environment has been discovered which involves providing a localized environment where scale would preferentially form, where the localized environment is adjacent the general environment. Monitoring the deposition of scale in the localized environment is performed for the purpose of taking preemptive action to prevent scale deposition in the general environment once scale begins to form, or a certain threshold is reached. Scale is removed from the localized environment so that monitoring can be performed by the probe again. Preemptive action will often be the introduction of a scale inhibiting agent into the general environment. An apparatus for practicing the method of predicting and preventing scale deposition in a general environment is also described.
