Abstract
Besides water, raw methanol produced from steel mill gases within the Carbon2Chem® project contains dissolved carbon dioxide. Refractometry and densimetry were investigated as analysis methods to analyze raw methanol samples quickly and reliably. To verify existing calibration curves, a set of standard solutions from pure chemicals was produced. Experimental results differed significantly from published refractive index data, especially in the range of high methanol weight fractions, which are of particular interest for the Carbon2Chem® project.
