High Yield Pulping Process

Process intensification in mechanical pulping

Process intensification is a term used in the chemical process industry for major improvements in the process design leading to radical changes in process complexity, equipment size and efficiency. We suggest that a similar approach is applied in the pulp and paper industry. We have focused on the production of mechanical pulp, but a similar approach can be applied to other areas within the pul...

Effect of Integrating Xylan Extraction from E. grandis into the Kraft Pulping Process on Pulp Yield and Chemical Balance

Kraft mills have the potential to pre-extract hemicellulose from wood as another value added product. The impacts of pre-extracting xylan on pulp and handsheet properties, sodium and sulfur balances, and chemical make-ups in the kraft pulping process of Eucalyptus grandis were assessed. Xylan extractions using white liquor, green liquor, and NaOH were done under varying extraction times, temper...

High Yield Micro Fabrication Process for Biomimetic Artificial Haircell Sensors

We have developed artificial haircell sensors based on an improved plastic deformation magnetic assembly (PDMA) method. The PDMA method is uniquely capable of realizing three-dimensional microstructures in an efficient, ICcompatible manner. We have improved the design of the PDMA structure to significantly increase the yield by eliminating stress concentration. The robustness of the fabricated ...

High Yield Production Process for Shigella Outer Membrane Particles

Gram-negative bacteria naturally shed particles that consist of outer membrane lipids, outer membrane proteins, and soluble periplasmic components. These particles have been proposed for use as vaccines but the yield has been problematic. We developed a high yielding production process of genetically derived outer membrane particles from the human pathogen Shigella sonnei. Yields of approximate...
