... inhibitors for copper and its alloys are triazole based chemistries, such as Tolyltriazole* (TT), Benzotriazole* (BZT), and Chlorinated Tolyltriazole (Cl-TT). 1-2 The molecular structures are shown below. The triazoles work as yellow metal corrosion inhibitors by forming an inhibitor film on the surface...

... chemistries that are not identified as fast-acting, will facilitate endospore formation. Clostridium sporogenes was chosen as the test organism, as this genus is commonly found in oilfields, its members possess metabolisms that are known to cause corrosion, and they have previously been described...

... corrosion and SCC of carbon steel, most notably NO 2 - . An essential part of managing the integrity of these storage tanks is to define certain waste chemistry control limits with respect to pH, aggressive species, and inhibitive species. metals & mining Subsurface Corrosion materials...

... correlation to experimental datasets (either laboratory or field based). Commonly measured input parameters include measured biological activity, fluid chemistry, process conditions (e.g. temperature, pressure and flow rate) and physical properties (e.g. pipe material and geometry). Mechanistic models also...

... consuming process that often leads to poor passivation. This paper details the use of non-phosphate and non-zinc corrosion inhibitors, able to rapidly passivate and protect galvanized coatings. This newly developed chemistry can also be applied after a utilized galvanized surface has been placed in service...

Routine monitoring with serial dilution culture techniques...

... gases are recognized concepts in the oil and gas industry with non-ideality corrections frequently used in the design and operation of hydrocarbon processing facilities. Application of non-ideal solution chemistry to corrosion testing and modeling is not as common, even though supercritical conditions...

... of construction, operating practices, as well as the impact of water chemistry. Regrettably, misleading interpretations exist about the FAC mechanisms that often offset mitigation efforts. The paper provides pragmatic insight on the main root causes and amelioration strategies. INTRODUCTION Flow-accelerated...

... to help improve fractionation. Fortunately, the water and water/process modeling and chemistry capabilities have expanded to accommodate the refiners optimization and maintenance goals. Although neutralizing amines and filmers have been used for decades, technology improvements in the treatment chemistry...

... ABSTRACT This paper introduces a new way of using the desalting process to help control overhead corrosion. A new adjunct chemistry, fed in combination with the emulsion breaker is shown in case histories to be able to increase the removal of salt, ammonia, and amines in the desalter, reducing...

... Chemistry in Modern Industrial Boilers. 1,2 This work is currently in progress. The Schikorr reaction and oxidation vs. reduction chemistry will also be discussed as they relate to industrial boiler systems and the use of reducing agents. It will also be discussed how the coordinated phosphate program...

... Abstract Galvele introduced a new quantitative framework for localized corrosion through his seminal paper on acidification and chloride accumulation in pits and the need for a critical product of current density and pit depth to sustain this local chemistry. This concept, introduced in 1976...

..., chemical scavengers are often applied, typically topside and post-separation. Downhole injection has the benefit of providing the opportunity to remove H 2 S at the earliest point of the production system, but more traditional chemistries can significantly impact scale deposition downhole or cause...

... Abstract A large number of CO 2 dependent chemical, electrochemical and mass transport processes occur simultaneously on and close to the corroding steel surface. The various reactions respond differently to changes in CO 2 partial pressure, temperature, water chemistry, flow and other...

... alloys. The biggest factor that controls the corrosion behavior of nickel alloy UNS N10276 is the microstructure. There are two primary options for changing the microstructure of cast alloys: chemical composition and heat treatment. This project focused on the effect of both chemistry and heat treatment...

... Abstract To ensure and optimise oil and gas production and whilst maintaining integrity, chemicals are added to avoid hydrate formation, corrosion, scaling and to stimulate production. To be successful on all areas a critical balance of chemistry is required where all aspects need...
