Carbon dioxide capture from reforming gases using acetic acid modified chemical absorbents
carbon dioxide gas is a major problem in the production of natural gas. it may also contributes to operation problems such as foaming, corrosion, high solution viscosity and fouling, thereby decreasing the plant life. this study presents experimental results on the evaluation of modified amine solut...
