Abstract
A distillation process utilizing hardwood black liquor samples from Mead in Escanaba was used to determine the effect of ph on non-condensible gas evolution.
Ph was found to be highly negatively correlated to the volumetric production of non-condensible gas. The correlation for all the black liquor samples tested was found to be greater than -.990. This indicates that as ph increases the volumetric production of non-condensible gas decreases.
Ph was found to be more correlated to the effect of gas volume reduction in the ph range of I 1.5 to 12.5.
Non-condensible gases produced in the fifth and sixth effects were found to represent approximately 40 percent of the total amount of non-condensible gas evolved in the evaporator system at Mead in Escanaba.
