We have experiences in desgining and commissioning light/dense sodium carbonate making line .Have developed two processes ,Ammonia-soda Process(Solvay Process) and Combined-soda Process(Hou's Process) .

Ammonia-soda Process

Ammonia-soda Process(Solvay Process)
Use underground brine or crude salt and limestone as raw material, remove the calcium and magnesium impurities from brine, re-absorption of ammonia into ammonia brine, and then carbonated ,will generate sodium bicarbonate crystallization.Filter and then calcined ,will generate soda ash.Filtered mother liquor, add lime ,reaction and distillation,recycling ammonia.

Combined-soda Process (Hou's Process)

For this process ,we will design according to your special demand because there are lots of choices.Now we recommend the most popular method for reference .It is Carbonation one time, absorption of ammonia two times, add salt one times and ice cooling methods.
