FOERFARANDE FOER STYRNING AV ALKALISK CELLULOSAKOKNING MEDELST EN SNABB ANALYSATOR, VILKEN MAETER OORGANISKA OCH ORGANISKA KOKVAETSKEKOMPONENTER.

摘要

The invention relates to a method of controlling an alkaline pulping process, sulphate pulping in particular. According to the invention, the concentration of the dissolved components as well as the concentration of the residual cooking chemical are measured. The measurements are carried out by means of an analyzer positioned outside of the cooking process in a separate liquid flow. The measuring devices are per se known detectors. The cooking process is observed and the necessary corrections are made on the basis of the measuring results. (Figure 1)
