This study investigates the requirements for modeling of acid sulfite pulping with regard to the recovery of cooking chemicals, especially SO2. Such a model has to predict the temporal change of SO2 distribution on solid, liquid and gaseous phase in the digester throughout the whole pulping process, dependent on the pulping parameters: total SO2, free SO2, liquor-towood ratio, temporal temperature course, maximum pressure and time. The approach is based on the mass balance of SO2 to achieve… CONTINUE READING
