| Input 1 |
sulfite spent liquor (SSL, 33% dry content) from spruce wood pulping (400,000 t/y
)
|
| Output 1 |
ethanol (15,800 t/y
)
|
| Technology Brief |
Pulp for the paper mill is produced by cooking spruce chips with acidic calcium bisulfite cooking liquor. Hemicellulose is hydrolyzed to various sugars during the cooking process. After concentration of the SSL, the sugars are fermented and ethanol is distilled off in several steps. A part of the 96% ethanol is dehydrated to get absolute ethanol.
