Title: Hazen Charles Thomas: Innovator in Pulp Processing Technologies
Introduction
Hazen Charles Thomas is a notable inventor based in Green Bay, WI (US), recognized for his contributions to the field of pulp processing. He holds a total of 3 patents, showcasing his innovative approaches to improving the efficiency and effectiveness of pulp bleaching and processing methods.
Latest Patents
One of his latest patents is titled "Process for high temperature peroxide bleaching of pulp with cool discharge." This innovative process involves retaining pulp at high temperature and pressure to enhance bleaching activity while cooling the pulp before discharge from the pressure vessel. This method results in lower energy consumption and a nonviolent discharge. The use of a heat exchanger allows for the cooling of the pulp with recycled filtrate containing residual peroxide, promoting further bleaching during atmospheric retention. Additionally, the heat exchanger heats a water stream for earlier use in the pulping process, leading to significant cost savings.
Another significant patent is "Process for using a phloroglucinol color delta to control blending, deinking and bleaching of groundwood-containing secondary pulp." This method characterizes the initial color of the pulp and its response to a phloroglucinol stain, which serves as a better indicator of processing needs for secondary pulps. The color difference helps target suitable products for the pulp, optimize bleaching and deinking strategies, and enhance fiber blending for specific products.
