Generating Sodium Hydroxide from Sodium Sulfate and Calcium Hydroxide

A company produces crystalline sodium sulfate as a byproduct, using sodium hydroxide as one of many feeds within the process. They seek to use the available compounds to produce it in situ. The company seeks a process that uses sodium sulfate and calcium oxide to produce sodium hydroxide, and could accept an aqueous product from a process with the lower limit being about 8% caustic solution with moderate sulfate content. Low calcium content in the caustic is important. The company can accept the formation of gypsum as a by-product of the process.
