Henry's law constant of methanol in pulping spent liquors

A direct headspace gas chromatographic method was used to measure Henry's c onstants of methanol in pulping spent liquors. The liquors were from kraft pulp mills and laboratory pulping experiments using various wood species. A ll liquors studied had a total solids less than 25%. It was found that temp erature and concentration of inorganic solids, mainly sodium salts, are the two variables that significantly affect the Henry's constants of methanol. A two-parameter (temperature and liquor total solids content) correlation was developed based on the experimental data and is reported in this study.
