Corrosion inhibition effect of four inhibitors on SA106 Gr.B steel in coal-based syngas produced water

Juanbo Liu et al.

Summary: The stripper tower in a coal gasification unit is prone to severe corrosion, which can lead to equipment damage and toxic gas leakage. This study investigates the effects of medium concentration on corrosion behavior in coal-based syngas produced water using techniques such as X-ray diffraction and scanning electron microscopy. The protective performance of different inhibitors is also explored using electrochemical measurement and weight loss experiments. The results show that the concentration of H2S and the ratio of C(CO2)/C(H2S) have a significant impact on corrosion behavior, and it is important to control their concentration within a reasonable range. Four inhibitors, especially MBQA and PD, exhibit promising inhibition performance at appropriate concentrations. Furthermore, compounding MBQA and PD inhibitors shows an optimal inhibition performance with 95.5% efficiency. This study provides a new approach to effectively protect the top of the stripper tower in a coal gasification unit.

Localized Corrosion Mechanism of Q125 Casing Steel in Residual Acid Solution during Oil Reservoir Acidizing

Wei Yan et al.

Summary: This study investigates the localized corrosion mechanism of Q125 casing steel in residual acid solution with Mannich base type inhibitors during oil reservoir acidizing process. The corrosion behavior and inhibition efficiency of Q125 casing steel in fresh acid and residual acid solution with and without the Mannich base type inhibitor were studied.
