Process of removing calcium and obtaining sulfate salts from an aqueous sugar solution |
abstract |
The present invention provides a process for obtaining a product stream comprising one or more sulfate salts of potassium, sodium or ammonium from a sugar stream resulting from [processing a lignocellulosic feedstock, said sugar stream which includes calcium sulfate and one or more of these sulfate salts. The process comprises (i) treating the sugar stream to remove calcium, thereby producing a sugar stream containing substantially no calcium, and obtaining a salt stream comprising a calcium salt; (ii) choosing a feed stream that is either (a) a clarified salt stream derived from the salt stream of step (i) after removal of calcium therefrom; or (b) the sugar stream containing substantially no calcium that is produced in step (i); (iii) introducing the feed stream chosen in step (ii) to an ion exchange bed; and (iv) regenerating the ion exchange resin bed of step (iii) with sulfuric acid to produce the product stream. |
