Abstract
A high efficiency batch sulfuric acid reprocessor system that is capable of producing high purity acid through distillation. Methods of use are also provided. The distillation is monitored and controlled in accordance with temperatures of the system, in particular, the temperature of the column and the temperature of the vapor in a condensing chamber. A stream splitter enables the invention to selectively collect high purity product as well as remove waste or recycle condensate as reflux.
