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： 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： 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： 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： The use of a composition that includes a metal salt and an oil soluble amine formaldehyde reaction product scavenges H2S that is present in aqueous fluids (e.g. produced water liquid streams), natural gas and in oil and mixtures thereof (e.g. mixed production streams that contain all three phases) better than either component when used alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over each component when used alone, in the same total amount. Non-limiting examples of the metal salt include zinc or iron carboxylates, and a non-limiting example of an oil soluble amine formaldehyde reaction product is the reaction product of dibutylamine with formaldehyde.
