APPARATUS AND METHOD FOR MEASURING VENT GAS FLOW RATES AND PARAMETERS IN PULP AND PAPER PROCESSING |
| 摘要 |
An inert gas such as helium is employed as a tracer gas in a pulp and paper mill to determine the utilization of oxygen by an aqueous cellulosic pulp particularly, as well as other parameters, in an oxygen delignification or extraction in which oxygen is dissolved in the pulp and reacted to solubilize lignins and reduce the requirement for chlorine-based bleaching chemicals.
