PROCESS FOR THE REGULATION OF THE DEGREE OF CAUSTIFICATION DURING THE PREPARATION OF NEW LAUNDRY AND APPARATUS FOR IMPLEMENTING THE PROCESS

摘要

According to this process, calcium oxide is added while testing a sample and the addition of calcium oxide in the installation is adjusted according to the value obtained, so as to obtain the desired degree of caustification. . In addition to this sample, a sample of the lye supplied to the lime dissolver of the causticizing plant is also taken and analyzed on the basis of the carbonate ion content thus obtained in the lye supplied to the causticizing plant, as well as in the laundry leaving the latter.
