Optimizing Sour Gas Qualification Testing – Modeling the Effects of Temperature and Total Pressure on H2S Fugacity, Activity, and Solubility Coefficients

Traditionally, sour severity of high-pressure, high temperature (HPHT) oil and gas production wells were assessed by H2S partial pressure (PH2S): The mole fraction of H2S in the gas (yH2S) multiplied by the total pressure (PT). While PH2S is appropriate for characterizing the sour severity of wellbores operating at low total pressures (e.g., PT < 35 MPa) and/or for highly sour systems (e.g., yH2S > 1 mol%), PH2S usually over-predicts the actual sour severity of HPHT systems, leading to sub-optimal material selection options.

Organic corrosion inhibitors for the prevention of stress corrosion cracking in 5XXX-series aluminum

5XXX-series aluminum has been used in multiple naval vessels because it offers excellent strength to weight ratios, weldability and low cost. Although 5XXX series aluminum alloys generally provide excellent corrosion resistance, exposure to moderately elevated temperatures (e.g., solar exposure) results in sensitization due to precipitation of the beta phase (Mg2Al3) at the grain boundaries. The sensitization of marine grade aluminum and subsequent material degradation due to stress corrosion cracking (SCC) and intergranular corrosion (IGC) is a severe problem, causing expensive repairs and out of service time.

Organizing And Developying Volunteers To Preserve Historic Army Tanks For a Military Museum

Product Number: 51218-095-SG

Author: Susan Boyd

Publication Date: 2018

$20.00

In the summer of 2014 Vulcan Painters spearheaded a project to do surface preparation and recoat seven historic military tanks, asking for help from the industrial painting community, from contractors and suppliers. The aim of the project was to finish the work without expense to the foundation that sought to build a new museum to house 200 years of U.S. Army armor and cavalry history.

Failure of water/wastewater mains can result in high visibility repairs customer inconvenience and replacement costs. Preventive measures such as condition assessment for early recognition of corrosion in aging infrastructures is crucial for agencies from resiliency safety and economic standpoints but is not regulated as in the oil & gas industry. Internally deployed tools/technology or external excavations for direct assessment techniques provide valuable insight on the existing condition of buried structures but at a significant cost in terms of shutdown and technology expenses in addition to safety concerns for manned entries into confined spaces. Because of the cost and safety implications large diameter cement mortar lined (CML) pipe extensive and recurring direct assessments are less common in the water and wastewater industries. Indirect assessment techniques particularly the over-the-line potential surveys for condition assessment of water/wastewater lines can be conducted to determine active external corrosion areas. Traditionally over-the-line potential surveys were applied to electrically continuous pipelines. Most water/wastewater pipeline designs utilize rubber gasket bell-and-spigot joints. Unless electrical continuity is intentionally designed for the pipeline such joints result in a pipeline with no electrical continuity. This paper presents multiple case studies where over-the-line potential surveys were successfully applied on electrically discontinuous water pipelines. The results of over-the-line surveys correlated well with direct assessment techniques. The paper presents the methodology and results of such assessments and findings for various pipe materials.
