View Solution. In the Solvay process for producing sodium carbonate (N a2CO3), the following reactions occur in sequence. N H 3 +CO2 +H 2O → N H 4H CO3. N H 4H CO3 +N aCl → N H 4Cl+NCO3. 2NCO3 Δ −→ N a2CO3 +H 2O +CO2. How much of N a2CO3 would be produced per kg of N H 3 used if the process were efficient?

Solvay Process Steps. Firstly, brine is saturated using ammonia, followed by CO2 and is cooled later. The NaHCO3 gets precipitated out of the solution. NaCl + NH3 + CO2 + H2O → NaHCO3 (s) + NH4Cl. This is the Solvay Process reaction equation. The precipitates of NaHCO3 are filtered, dried, and heated.

The introduction of the calciner transformed the cement production process. Short kilns and tall preheater towers replaced long kilns; a change that dramatically improved process efficiency. But it also came with a challenge. Calciner temperatures are much lower than those in the kiln – and this posed a conundrum for calciner burner design.

For these reasons, the design of the calciner is one of the key elements in the system. An optimal fluidisation was proposed to control surface overheating and avoids peak temperatures. As small particles are required for fast calcination it seems more suitable a co-current entrained flow calciner reactor design.
