Title: Sture Erik Noreus: Innovator in Cellulose Pulping Technology
Introduction
Sture Erik Noreus is a notable inventor based in Husum, Sweden. He has made significant contributions to the field of cellulose pulping technology. His innovative approach focuses on improving the efficiency of sodium utilization in sulfate cellulose pulping processes.
Latest Patents
Noreus holds a patent for a method of producing oxidized white liquor. This cyclic process is designed to utilize sodium values effectively in sulfate cellulose pulping. The method ensures that sodium losses are minimized, leading to a sodium surplus. The process involves pulping cellulosic material with a liquor containing sodium hydroxide and sodium sulfide. It also includes steps for separating spent pulping black liquor, evaporating and combusting it to recover sodium values, and recycling white liquor back into the pulping process. The improvement lies in maintaining sodium balance by oxidizing the white liquor and using it as a source of alkali in other cellulose pulp treatment processes.
