Performance of <i>N,O</i>-Carboxymethyl Chitosan as Corrosion and Scale Inhibitors in CO<sub>2</sub> Saturated Brine Solution

The presence of salts and dissolved gas like CO2 that is carried with natural gas and crude oil along the pipeline is the main reason for corrosion and scale formation. These problems are usually resolved separately by corrosion inhibitors and scale inhibitors or acidification. Meanwhile, utilizing...
