PROCESS AND INSTALLATION FOR PREPARING BLACK LYE DURING THE MANUFACTURING OF CELLULOSE SULPHATE FOR REGENERATION

摘要

the process according to the invention refers to the preparation lesiei black results from manufacture of pulp sulphate, for the purposes of regeneration.the process consists in treating with salt glauber in quantity as to cover losses resulting in the manufacture of chemical pulp.the chute is constituted of a mixture of black lesiei salt glauber, a reservoir of reception,where the amount of soda and a pump for recirculating the black lye and transport for regeneration.the system is worth it particularly to chemical plants which have close factories of cellulose sulfate and celofibra factories or viscose process which result in heart glauber salt.
