Evaluate a sulfuric acid production facility that uses the contact method with one absorber. Humid air at 25C and relative humidity of 0.55 is dried using sulfuric acid 99%, the product. The acid gets diluted to 98%

and is used to absorb SO3 produced at the converter. Assume that the molar ratio of dry air to sulfur is 10:1. Sulfur is burned with the dry air producing SO2. The gas mixture is sent to the converter, which operates isothermally at 1.5 atm and 700K. This stream is sent to the absorber.

In the absorber, water, sulfuric acid 98%, and the gas are put into contact so that sulfuric acid 99% is produced. Compute the amount of sulfuric acid produced (99%), the flowrate of H2SO4 98%, the flow rate of water fed to the absorption tower, and the fraction of sulfuric acid used to dry the initial air.
