The product should not have any odor, should have a high flash point, and mitigate corrosion in the presence of drill cuttings, oxygen, and sour gases. Significant laboratory development...

... not create halogenated organics and does not introduce oxygen into the system. Performic acid provides unique advantages for use in many energy related applications, particularly in water treatment. Treatment using performic acid, at 0.5ppm, provides a microbial reduction equivalent to 3 logs of bacteria/mL...

... In order to measure the amount of dissolved oxygen obtained in condition 1, a polarization curve was performed as described above, using a palladium electrode. The area of this electrode was 0.322 cm 2 . Rotating Cage Autoclave Test (RCA) RCA were used to confirm the potentiodynamic...

Conventional wisdom holds that chloride ion and oxygen play major causative roles. The authors' findings, however, identify...

... Abstract At elevated temperatures in aqueous solution, partially hydrolyzed polyacrylamides (HPAM) experience hydrolysis of amide side groups. However, in the absence of dissolved oxygen and divalent cations, the polymer backbone can remain stable so that HPAM solutions were projected...
