摘要
Abstract
The solvent method for CO2 capture has the advantages of mature technology and low cost,and is widely used.As commonly used absorbents,organic amines have the advantages of fast absorption rate and large absorption capacity.However,due to the chemical reaction between organic amines and CO2,the solution becomes corrosive,resulting in corrosion of equipment pipelines.The corrosion mechanism of organic amine solutions was reviewed.Hydrogenated amine ions,bicarbonate ions and water molecules are the main oxidants,which provide conditions for the occurrence of corrosion.The effects of the types and concentrations of organic amine solution,CO2 loadings,temperatures,O2 content and degradation products on the corrosiveness of the solution were discussed.Among them,CO2 loadings and temperatures are the main factors.The methods of using inorganic and organic corrosion inhibitors,adjusting the pH value of the solution and using stainless steel materials were summarized.The organic corrosion inhibitors for amine solutions are more worthy value of attention.The development direction of future corrosion inhibition technology was put forward.It is necessary to develop new corrosion inhibitors and combine them with corrosion resistant materials,which can provide a reference for further research and solving the corrosion problem of organic amine solutions.关键词
