In Soda Pulp from Aspen, Henry E.
Surface examines how cooking variables affect yield, bleaching losses, and chemical use in the soda pulping of aspen. The work blends practical lab tests with measurements of caustic soda, bleaching powder, and current industrial practices to show how process changes influence results.
Readers will gain a grounded view of how variables like chemical concentrations, cooking time, and pressure shape pulp yield, bleaching needs, and overall chemical costs. The document includes descriptions of experimental methods, analyses of soda liquors, and early autoclave testing in aspen, offering a clear look at the science behind pulping decisions.
- How changes in caustic soda concentration and cooking duration impact yield and chemical use
- How bleaching requirements and losses respond to different cooking conditions
- Methods for estimating chemical costs per ton of pulp and practical test setups
- Microscopic and analytical approaches used to study fiber characteristics and pulping liquor composition
Ideal for readers of pulp technology and forestry-based materials, this edition provides concrete, procedure-based insights useful to researchers and industry professionals alike.
