PROCESS FOR RECOVERING SALT DURING A LIGNOCELLULOSIC CONVERSION PROCESS |
摘要 |
<p>The present invention relates to a process for generating steam and recovering salts during a lignocellulosic conversion process. The process comprises de-salting a still bottoms stream; incinerating a stream comprising lignin and the de-salted still bottoms stream in an incinerator; and utilizing the heat generated from said incinerating to produce steam. Further provided is a process that comprises feeding a concentrated still bottoms stream to a crystallizer and forming insoluble solids therein comprising salts. Furthermore, the invention relates to a process for recovering salts from a lignocellulosic conversion process, which process comprises the addition of solvent to a still bottoms stream to precipitate salts therefrom. Also provided is a still bottoms composition, a fertilizer product and a composition for incineration.</p> |
