5.13: Industrial Chemical Reactions - The Solvay Process ...

16/03/2021  The calcination of limestone (Reaction 5.13.4) provides ample carbon dioxide to make up for inevitable losses from the process, but some additional ammonia has to be added to compensate for any leakage. What about the percent yield and atom economy of the Solvay process? The percent yield of reaction generating the product, Reaction 5.13.1, can be expected to be significantly less than
