What was the analysis of the gas stream from the process
Carbon dioxide may be produced by reacting limestone with aqueous sulfuric acid. Limestone, made up of calcium carbonate, magnesium carbonate and inerts, is fed to a process where it is reacted with a 12% H2SO4 solution. Much of the CO2 and some of the water are removed as a gas and the residue from the process analyzed as follows:
CaSO4 8.56% MgSO4 5.23% H2SO4 1.05% Inerts 0.53% CO2 0.12% Water 84.51%
a) What was the composition of the limestone fed to this process?
b) What percent excess acid was used?
c) What was the analysis of the gas stream from the process?
