HEAT RECOVERY FROM CONCENTRATED SULFURIC ACID |
摘要 |
A method and apparatus for the recovery of heat from a sulfuric acid process are provided. Sulfur trioxide is absorbed into hot concentrated sulfuric acid, acid having a concentration greater than 98% and less than 101% and a temperature greater than 120 created by the exothermic reaction is recovered in a useful form in a heat exchanger. Gas leaving the primary heat recovery absorption zone is cooled by contact with sulfuric acid in a secondary absorption and cooling zone located above the primary absorption zone in the tower. |
