A PROCESS FOR STABILIZING THE PH OF A PULP SUSPENSION AND FOR PRODUCING PAPER FROM THE STABILIZED PULP

摘要

The invention relates to a process for stabilizing the pH of a pulp suspension with buffering agents and to a process for producing paper from a stabilized pulp suspension. The alkalinity of the pulp suspension is increased by a combination of an alkali metal hydroxide feed and a carbon dioxide feed. Said feeds provide a significant buffering effect which stablilizes the pH of said pulp suspension for the paper making process.
