Sulfuric Acid Limestone Gypsum Reaction

2 preparation gypsum from limestone in this process limestone caco 3 is reacted with dilute sulfuric acid h 2 so 4 in the reactor at the operating conditions of temperature at 93 176c and pressure at 1 atm the resulting product from the reactor is then sent into a separator to remove its impurity the reaction was as follows caco 3.
