Solvay’s Process – Sodium bicarbonate Formation :
Separation of sodium bicarbonate crystals from mother liquor is achieved by means of centrifuges or vacuum filters. After washing of the cake to eliminate mother liquor chloride, it is sent to calcination. The liquid phase “mother liquor” is sent to the distillation sector […]

Solvay’s Process – Sodium bicarbonate Formation :
Precipitation: As mentioned in the ammonia absorption step this is a closed loop process. The purified brine is allowed to react with the waste gas ammonia to form the ammoniacal brine. This ammoniacal brine is then allowed to react with excess carbon dioxide […]

Solvay’s Process – Ammonia Absorption :
This is a closed loop process. Closed looping is necessary to ensure that no free ammonia is let out to the atmosphere as such. And it is a highly important step to prevent environmental pollution. This step is the initial processing step in the […]

Solvay’s Process – Lime Calcination :
Particle size distribution of the limestone from quarries is generally between 40 and 200 mm. The more homogeneous it is, the better the lime kiln will work but the greater the amount of limestone fine by-product produced at the quarry. Coke, and rarely coal, […]

Solvay’s Process – Lime Calcination :
Limestone is a naturally occurring mineral that can be mined and ground to meet the process requirement. The naturally occurring deposits are originated from calcareous shell and skeletons of biota as well as chemical and bio-chemical precipitation in the sea during geological ages. For […]

Solvay’s Process – Lime Calcination :
Lime calcination process produces raw burnt lime and approximate content of CaO in this raw calcined lime is about 75 to 90 percent. However this raw lime cannot be used as such in the Solvay’s process. This is because it is highly difficult to […]

Solvay’s Process – Lime Calcination :
In the lime kiln operation, we should consider 2 factors as important; one being the quantity of gas and another composition of gas. The operational capacity of the kiln is purely determined by the amount of lime required for ammonia recovery in the distillation […]

Solvay’s Process – Lime Calcination :
As discussed in the earlier blog, the lime calcination kiln used in Solvay’s process is different from the other normal kilns used for calcination as this kiln has to consider the production of outlet gases with maximum amount of CO2 in them. The CO2 […]

Solvay’s Process – Lime Calcination :
Lime Calcination is a multi-purpose step in the Solvay’s process. This step is essential to produce milk of lime production and equally important in generating excess Carbon dioxide that is used in the carbonation process. So while selecting a kiln for lime calcination we […]

Solvay’s Process – Brine Purification :
The alkaline reagent can be lime milk or sodium hydroxide. Usually milk of lime is used as the reagent because this is produced in abundant for ammonia recovery. Process should consider sufficient settling time for letting the precipitation process to happen and let settling […]
