The Polymer Electrolyte Membrane Fuel Cell (PEMFC) is attracting interest as a generator of electricity that does not emit greenhouse gases, provided that hydrogen is produced via clean processes. However, their large-scale commercialization is still limited by high cost and limited durability. As essential elements of the PEMFC, the bipolar plates (BPPs) enable the transport of electrons to the external circuit, guarantee the mechanical assembly of the cell, distribute the reactive gases, and evacuate the water.

Components utilized in oil field operations are often exposed to harsh environments. Corrosion and wear of components and piping can be considered one of the main causes of failure. These components are exposed to high flow rates, high pressures, and other environmental conditions.

Nowadays, titanium-based alloys are commonly used in biomedical applications as, for example, materials for dental implants or hip replacements. Their good corrosion resistance, biocompatibility and high mechanical properties for a relative weight make them good candidates. However, improvements in the design of these alloys for biomedical applications need to be made.

The development of combination products for scale and corrosion inhibition for fields producing at high downhole temperatures (~150C) and that generate produced waters with high Calcium concentrations can be a challenging undertaking. Traditional phosphonate scale inhibitors can be very effective; however they have been shown to form insoluble inorganic scales at high calcium concentrations that can plug and fail capillary strings. The development in this work considered the use of polymeric type scale inhibitor and a newly recently introduced high temperature corrosion inhibitor. Again because this is a high temperature application the evaluation of the corrosion performance can also be challenging due to the difficulties derived from attempting to prevent the scaling process while trying to obtain meaningful corrosion performance data. The developed combination product was stable at 150C compatible with capillary string materials and outperformed an incumbent product based on a phosphonate scale inhibitor and a more traditional type of corrosion inhibitor.

The Salton Sea KGRA has long been known for its power generating potential however the corrosivity of the hypersaline fluid has limited power generation as well as the production casing material choices. In the 1990’s titanium grade 29 was utilized very successfully to line nearly all of the energy producing wells in this field. The material proved to be an excellent choice and has given 20-25 years’ service life to date. Despite its excellent performance grade 29 is a high strength titanium alloy that is expensive to manufacture and finish. Recent wells (2012 and beyond) have utilized other materials that were less expensive upfront but appear to be degrading at a much faster rate than the grade 29 titanium alloy. To date these newer wells have required repairs in as little as 2-3 years after start-up. TIMET has recently developed several new alloys that will address both the cost and performance issues seen in this geothermal field. This paper will highlight the corrosion performance of these new alloys along with their more cost effective manufacturing processes.

Objectives the scale problem related to the formation of iron sulfide is commonly found during oil and gas productions in sour environments using low corrosion resistant carbon steel equipment and pipes. When hydrogen sulfide gas is evolved resulting from sulfate reducing bacteria or thermal decomposition of sulfate in the presence of iron from various corrosion processes in downhole iron sulfide can quickly precipitate. Although iron sulfide scale is not as common as carbonate and sulfate scales it is difficult to inhibit especially at high temperature conditions due to its low solubility and fast precipitation kinetics. Because efficient inhibitors for iron sulfide scale have not been found the application of iron sulfide dispersants could be an alternatively feasible method to control iron sulfide scale problems. There have been commercially available dispersants for iron sulfide scale particles but can transfer iron sulfide scale to the oil phase causing another issues during oil and gas operational activities. In this study we identify efficient and effective inhibitors/dispersants for iron sulfide scale while maintaining iron sulfide in the water phase as well as preventing iron sulfide from transforming to more stable and insoluble forms. We also investigate different operational and solution conditions and characterize iron sulfide solids using instrumental analytical techniques to understand scale controlling reaction mechanism.MethodsMore than 50 different chemical formulations are investigated for iron sulfide scale inhibition or dispersion in a batch reactor system under a strictly anoxic environment. To produce an anoxic environment we prepare all solutions in air-tight apparatus while sparging ultra-high purity grade argon gas (DO < 5 ppb). Reactions are carried out in temperature controlled glass reactors. Different operational and solution conditions are tested such as pH temperature ionic strength inhibitor concentrations and iron sulfide saturation index. Iron sulfide solids are characterized using SEM TEM DLS XRD and FT-IR and ferrous iron and sulfide concentrations in filtered solutions are analyzed using colorimetric methods with UV-VIS spectrophotometer.ResultsOur studies indicate that biocides such as tetrakis (hydroxymethyl) phosphonium chloride may not be effective inhibitors for iron sulfide scale. Amide-group containing polymeric compounds show a promising effect on dispersing iron sulfide particles in water phase rather than dissolving them as with ethylenediaminetetraacetic acid. Other biodegradable and non-toxic polymer groups commonly used for nanoparticle stabilization for biomedical applications are also tested to disperse iron sulfide particles and demonstrate great dispersibility of iron sulfide in water. SEM analysis shows that polymer dispersed iron sulfides remain in amorphous iron sulfide unlike one without polymers which is transformed to gregite or pyrite after aged for 10 days at 75 ◦C. Characterizations of water soluble polymers dispersing iron sulfide and iron sulfides dispersed in polymers are ongoing. The operational and solution conditions for dispersing iron sulfide in polymer are also currently being investigated. Novel implicationsIron sulfide such as mackinawite has been reported as a corrosion product of steel pipes. Iron sulfide scale is hard to control due to fast precipitation kinetics and extremely low solubility. Commercial scale inhibitors do not effectively inhibit nucleation of iron sulfide solid and dispersants available on the market can often transfer iron sulfide particles to the oil phase causing an additional issue during oil and gas production activities. Moreover initially formed unstable amorphous iron sulfide could be transformed to stable form which is much more difficult to control. The our results of identifying iron sulfide dispersants to solve all issues mentioned previously and understanding of the mechanistic function of polymeric dispersants to optimize the processes would of great alleviate iron sulfide scale problem resulting in technical and financial benefits.

Geothermal energy is a cost-effective, reliable, sustainable, and environmentally friendly solution to produce electricity using the energy resources available underground. Binary plants are becoming more popular as it helps extract the most enthalpy. In binary plants, brine is cooled to its lowest possible temperature to maximize energy extraction.

Sour gases like hydrogen sulfide (H2S) are one of the main risks associated in the production and processing of oil and gas. H2S is a very toxic and pungent gas that causes problems in both the upstream and downstream oil and gas industry. Exposure to H2S, even at relatively low concentration can prove deadly and has many HSE implications.

The U.S. has more than 2.6 million miles of pipelines that transport natural gas and petroleum products. These pipelines are subjected to various potential threats (e.g., aging, harsh environment, natural hazard) during their service lives. Particularly, corrosion that results in loss of metal on external or internal surfaces of pipelines is one of the leading causes of the pipeline failure.

Aluminum alloys exhibit good resistance to atmospheric corrosion due to the presence of a fine, passive oxide layer. Nevertheless, these alloys are not immune to corrosion which can take the form of localized corrosion like pitting, intergranular or exfoliation corrosion. Thus, the assessment of the corrosion behavior of aluminum alloys under atmospheric conditions is a major topic for many applications including the aerospace industry.
