Latest Patents

John D Weston holds a patent for a method of pulping sawdust. This innovative process involves creating chemical cellulose pulp from sawdust by utilizing a static down-flow retention vessel. The method includes adding steam and cooking liquor to a flow of sawdust, resulting in a heated slurry at a cooking temperature of approximately 250-350°F. The slurry is then moved downward in the retention vessel under superatmospheric pressure while maintaining the cooking temperature for a duration of about 0.5 to 6 hours. The slurry, with a consistency of about 5-30%, is cooled below cooking temperature by diffusing cooling liquid through it, ensuring efficient processing.
