Corrosion of steel by carbonate‐bicarbonate solution for CO2capture
Materials and Corrosion, 2012AbstractHot alkaline solutions, such as potassium/sodium carbonate solutions, have been used for carbon dioxide removal and capture processes. This survey summarizes the available corrosion data of steels in the solution with carbon dioxide dissolved. Plant operating experiences and laboratory testing results are considered.

Determination of low uranium concentration in carbonate-bicarbonate solutions by X-ray fluorescence
Journal of Radioanalytical Chemistry, 1980A method has been developed for the direct determination of uranium in carbonate solutions by X-ray fluorescence. Uranium, in the concentration range 0.2–50 ppm, is first absorbed as the carbonate complex on an anion exchange resin and then determined by X-ray fluorescence.

Thermodynamics of aqueous mixed potassium carbonate, bicarbonate, and chloride solutions to 368 K
Journal of Chemical & Engineering Data, 1987Potentials for the cell without liquid junction H/sub 2/,Pt vertical bar K/sub 2/CO/sub 3/(m/sub 1/),KHCO/sub 3/(m/sub 2/),KCl(m/sub 3/) vertical bar AgCl,Ag are reported over a wide range of ionic strengths at temperatures to 368.15 K. Analysis of these results with the ion interaction model shows that only very minor changes in the previously ...

Corrosion, 1993
Stress corrosion cracking (SCC) characteristics of a range of pipeline steels immersed in a carbonate-bicarbonate solution were studied in terms of the deleterious effects of small-amplitude cyclic loading on threshold stress, together with the increase of crack nucleation and the decrease of average crack growth rates with increasing test times.

The Chemical Engineering Journal, 1976
Abstract The rates of absorption of pure carbon dioxide into aqueous sodium hydroxide and sodium carbonate-bicarbonate solutions have been measured using a liquid-jet column, a wetted-wall column and a quiescent-liquid absorber. The experimental results are analysed on the basis of the penetration theory for gas absorption accompanied by a two-step ...

Stress Corrosion Cracking of X-60 Line Pipe Steel in a Carbonate-Bicarbonate Solution
Corrosion, 1995An experimental system was developed to reproduce stress corrosion cracking (SCC) of API X-60 line pipe steels in highly alkaline (pH = 10) carbonate-bicarbonate (1 N sodium carbonate [Na2CO3] + 1 N sodium bicarbonate [NaHCO3]) solutions. Intergranular fracture developed in precracked specimens under very low frequency (40 cycles/day to 400 cycles/day)

The susceptibility to stress corrosion cracking (SCC) of the weld zone of carbon steel overpack, a candidate container for geological disposal of high-level radioactive waste, was studied using the slow strain rate testing (SSRT) technique. Several welding processes were applied to low-carbon steel, and SCC susceptibility of the weld zone, which ...

Crack growth model for pipelines exposed to concentrated carbonate–bicarbonate solution with high pH
Corrosion Science, 2010Abstract The crack tip strain rate (CTSR) and the dissolution/repassivation kinetics are the parameters controlling high pH SCC of pipeline steels because the repeated film rupture is the dominative mechanism. The CTSR is mainly produced by the crack tip advance and cyclic load.

Visible passive films are formed on the surface of 1010 steel at 325 K in a solution of 1 N NaHCO3 + 1 N Na2CO3 at anodic potentials up to −320 mVNHE inclusively. For potentials below −400 mV, they are dull and contain FeCO3. For −(390–320) mV, the films are thin blackish bright. Most probably, the diffraction peaks are caused by Fe3O4–Fe2O3. For −(430–
