A study of liquor side fouling in sulfite spent liquor evaporators

Creator:: Yoon, Woon-young
Abstract:: The effects of possible operating variables such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. The study pointed out that the Ca⁺⁺ concentration difference between heated surface and bulk is the most important factor for fouling...

The cloud point composition and flory-huggins interaction parameters of polyethylene glycol and sodium lignin sulfonate in water-ethanol mixtures

Creator:: Luh, Song-ping
Abstract:: In designing a solubility based separation process for solvent recovery of an organosolv pulping process, the phase behavior of polymeric lignin molecules in alcohol - water mixed solvent should be known. In this study, sodium lignin sulfonates (NaLS) samples were fractionated into three different molecular weight fractions using a partial...

Prediction of thermodynamic properties of aqueous electrolyte solutions

Creator:: Kim, Hee-taik
Abstract:: The research undertaken in this study deals with three topics related to the prediction of thermodynamic properties of electrolytes in aqueous solutions. In the first, Pitzer ion interaction parameters for 304 single electrolytes were evaluated from recently published osmotic coefficient data at 25°C by using multiple regression analysis to fit...

Sintering of fume deposits in kraft recovery boilers

Creator:: Techakijkajorn, Udom
Abstract:: Fume, sub-micron aerosal particles in the combustion gases, have been identified as a cause of extensive plugging and fouling in the heat transfer section of a kraft recovery boiler in kraft pulp mills. After the deposition on the heat transfer surface, fume deposits will undergo the sintering process which causes...
