My TAPPI Story: Leslie Petrie
We applied an indirect headspace gas chromatographic method to study the vapor-liquid phase equilibrium of methanol in weak black liquors to obtain empirical correlation of Henry’s constant of methanol for emission predictions in kraft mills. We used six samples from four kraft mills and five samples collected from our laboratory batch pulping processes under known pulping conditions. The samples have a good representation of black liquors yielded from hardwood and softwood, kraft and soda pulping processes. We found that temperature and total solids content are the two major factors that affect the Henry’s constant of methanol in black liquor. Linear regression analysis indicates that the methanol Henry’s constant in black liquors increases exponentially with the inverse of temperature in Kelvin and decreases linearly with the total solids content.
