What was composition of the limestone fed to this process

Reference no: EM13276715

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?
