Corrosion mechanism of steels in MDEA solution and material selection of the Desulfurizing equipment
(ESG, 2017)In the present study, the corrosion properties of three steel were evaluated in 45 wt.% Methyldiethanolamine (MDEA) solution, saturated to the hydrogen sulfide (H2S) and carbon dioxide (CO2) as in the oilfields. Corrosion ... -
Determination of Corrosion Inhibition Efficiency Using HPHT Autoclave by Gingko biloba on Carbon Steels in 3.5% NaCl solution Saturated with CO2
(ESG, 2014)Leaves extract of Gingko biloba (GBE) was characterized using mass spectrometry (MS) and Fourier transform infrared spectroscopy (FTIR) methods. The influence of GBE on corrosion of carbon steels (J55,N80, P110SS and C110 ... -
Relevance of electrochemical and surface studies to probe zanthoxylum schinifolium (sichuan pepper) as an effective corrosion inhibitor for N80 steel in CO₂ saturated 3.5% NaCl solution
(ESG, 2014)The inhibition of the corrosion of N80 steel in 3.5 wt.% NaCl solution saturated with CO₂ by the extract of Zanthoxylum schinifolium (ZSE) has been studied using electrochemical impedance ... -
Structural and chemical modifications of typical South African biomasses during torrefaction
(Elsevier, 2016)Torrefaction experiments were carried out for three typical South African biomass samples (softwood chips, hardwood chips and sweet sorghum bagasse) to a weight loss of 30 wt.%. During torrefaction, moisture, non-structural ... -
Towards practical applications of EQCN experiments to study Pt anchor sites on carbon surfaces
(Springer, 2018)This work investigates the viability and outlines the current challenges in electrochemical quartz crystal nanobalance (EQCN) experiments on supported Pt catalysts. EQCN experiments involving Pt supported on 2-D “surface-treated ... -
Use of HPHT autoclave to determine corrosion inhibition effect of poly(methyl methacrylate-co-N-vinyl-2-pyrrolidone) on carbon steels in 3.5% NaCl solution saturated with CO2
(Springer, 2015)The influence of poly(methylmethacrylate-co-N-vinyl-2-pyrrolidone), P(MMA-co-VP), on corrosion of carbon steels (J55, N80, P110SS and C110 steels) in 3.5 wt% NaCl solution saturated with CO2 was evaluated using static high ...
