Hi there,
I have been struggling with a problem which I have found while studying mass balances.
I feel like some guidence with this problem will help better my understanding of the subject.
I am first year chemical engineering so I do not have much knowledge as of yet.
The question is as follows:
Na2CO3 is reacted with Ca(OH)2 in the calciner via the reaction:
Na2CO3 + Ca(OH)2 -> 2NaOH + CaCO3
The CaCO3 washed in a thickener and converted to CaO in a kiln via the reaction:
CaCO3 -> CaO + CO2
The resulting lime (CaO) is hydrated in the slaker to again obtain Ca(OH)2:
CaO + H2O -> Ca(OH)2
The compositions are as shown on the flowsheet (which is attached)
In addition, m5 = 4 x m3, and m10 = amount of water in stream 1 (m meaning mass flow rate)
Assume all reactions have 100% conversion. Compositions are in wt%.
Using a1000 kg/hr basis, determine the number of kilograms of CaCO3 required per kilograms of Na2CO3 processed.
I do not even know where to start.
Any help would be greatly appreciated
