Title: Innovations of Jian E Jiang in Paper Pulp Processing

Introduction

Jian E Jiang is an accomplished inventor based in Glens Falls, NY (US), known for his significant contributions to the field of paper pulp processing. With a total of two patents to his name, Jiang has developed innovative methods that enhance the efficiency and environmental sustainability of pulp production.

Latest Patents

Jiang's latest patents include a method for modified digestion of paper pulp followed by ozone bleaching. This process allows kraft pulp to achieve a brightness of about 90 CPPA or greater without the use of chlorinated organic compounds, while maintaining commercially acceptable strength properties. The method involves extended delignification by adding kraft white liquor to recirculation loops in the digester, or by using conventional pulping followed by two oxygen stages. The pulp is then subjected to ozone bleaching with a dosage of less than 1.0%, preferably around 0.5%. Another notable patent focuses on multi-level sulfide content white liquor production and utilization. This innovation utilizes two different supplies of cooking liquor, one with low sulfide content and the other with high sulfide content, to optimize the viscosity/kappa ratio and pulp strength properties.
