// is our hypothesis that fermentative, acetogenic, and sulfaiereductng bacteria residing in pipeline faculties can influence corrosion through the production of carbon dioxide and acetate under the prevailing anaerobic conditions. The exacerbation of carbon dioxide corrosion of carbon sleel in the presence of acetic acid is a well-known phenomenon in the oil Industry. Doth chemical compounds c...

A photoelectrochemical study was made to compare Zr, Ti, Zn, Sn, Fe, and Cu in 1 N sulfuric acid and/or 1 N KOH. This group includes spontaneously passive, active-passive, and nonpassive metals. The apparent direct and indirect bandgaps and the flatband potentials were measured for the anodic oxides of each metal. (The bandgaps and flat-band potentials can be used to identify the anodic oXide.)...

The Sulfur-Iodide (SI) process has been investigated extensively as an alternate process to generate hydrogen through the thermo-chemical decomposition of water. The commercial viability of this process hinges on the durability and efficiency of heat exchangers/decomposers that operate at high temperatures under corrosive environments. In cooperation with the DOE and the University of Nevada, L...

In 2005, a 60 kt/a alkylation (ALK) unit began to resume production in the Second Oil Refinery Plant of Beijing Yanshan Petrochemical Company. There have been many leak cases from pipeline welds, valve body, flange, etc. After half-year period operation, process is stable. However, operation hydrofluoric (HF) acid ALK has suffered corrosion problems. are no clear answers and references followin...

Abstract The simulation and corrosion conduction of anti-acid brick in high temperature particle abrasion circumstances were tested with scanning electron microscopic, mechanical compression, X-ray diffraction. results showed the strength degradation rates Anti-acid 7.0% 17.8% different high-temperature acid conditions. water vapor environment permeated into after eroding crystal structure surf...

The inhibitive ability of 2,6-diaminopyridine, tartaric acid and their synergistic effect towards mild steel corrosion in 0.5 M HCl solution was evaluated at various concentrations using potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and weight loss experiments. Corresponding surfaces of mild steel were examined by atomic force microscope (AFM), field e...

A long term pilot scale experiment with steam reforming treatment technology was conducted for volume and weight reduction of uranium contaminated waste tri-n-butyl phosphate/n-dodecane solvent (TBP/dodecane) which was difficult to incinerate. The technology consists of a steam reforming process and a submerged combustion process. In the first process, TBP/dodecane is vaporized and pyrolyzed wi...
