A mini-flowloop was developed to study CO2 corrosion and corrosion/erosion interactions, and to assess the effectiveness of inhibitors under conditions that simulate multi-phase pipelines. The miniflowloop was used to study the effect of testing time, steel chemistry, velocity, temperature, fluid chemistry, sand and inhibitors on corrosion rates. The measured corrosion rates in inhibited and un...

Corrosion in CO2 Post-Combustion Capture with Alkanolamines – A Review — CO2 capture and storage plays an important part in industrial strategies for the mitigation of greenhouse gas emissions. CO2 post-combustion capture with alkanolamines is well adapted for the treatment of large industrial point sources using combustion of fossil fuels for power generation, like coal or gas fired power plan...

The simultaneous fluctuations of potential noise and current noise between two nominally identical X-65 mild steel electrodes were recorded using a ZRA (Zero Resistance Ammeter) to monitor localized CO2 corrosion in CO2-saturated 1 wt % NaCl solution at 80C. Electrochemical noise (EN) was obtained from both 11.6 cm and 1 cm specimens to understand how the surface area affects EN signals. Linear...

co2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. in this study, the lower part of es1 reservoirs in pucheng oilfield was introduced as the target reservoir. by studying the minimum miscible pressure in co2 flooding, the reservoir could achieve miscible flooding. long core displacement experiments prove...

A theoretical carbon dioxide (CO2) corrosion model was used to conduct numerical experiments, which allowed total insight into the underlying physicochemical processes. The focus was on factors influencing protective iron carbonate film formation and the effect that these films have on the CO2 corrosion process. It was confirmed that high bulk pH, high temperature, high partial pressure of CO2,...

The increase in CO2 concentrations and global warming will increase the carbonation depth of concrete. Furthermore, temperature rise will increase the rate of corrosion of steel rebar after carbonation. On the other hand, compared with normal concrete, high volume fly ash (HVFA) concrete is more vulnerable to carbonation-induced corrosion. Carbonation durability design with climate change is cr...

This work tried to decide whether an occasionally observed falling of straw stalactites in the Moravian Karst caves is caused by a hypothetical chemical corrosion. The straw stalactite wall was found to be formed by three calcite layers. The middle layer (a stalactite skeleton) was typically cracked in agreement with calcite cleavage. Some impact of chemical corrosion was positively identified ...

In 1996 Pots has written a two-dimensional (2-D) stochastic algorithm to simulate the morphology of localized attack. The rule based algorithm operates on the assumption that the morphology of corrosion attack depends on the balance of two processes: corrosion (leading to metal loss) and precipitation (leading to metal protection). The rules of the original algorithm were modified to enable sim...
