Solvay’s Process:
Ammonia recovery yield is controlled according to the permitted ammonia concentration in the released liquid. The lower the permitted value, the higher the quantity of stripping steam and therefore the global energy consumption, and the higher the cost of the ammonia recovery. This control can only be applied […]

Solvay’s Process:
One of the major achievements of the Solvay process is the high efficiency of the ammonia recycle loop. This loop circulates roughly 500 to 550 kg NH3/t soda ash from which the ammonia loss is less than 0.5 % of this flow rate. The purpose of this important […]

Solvay’s Process:
In some cases a small part of this “crude” bicarbonate, which although predominantly sodium bicarbonate also contains a mixture of different salts (ammonium bicarbonate, sodium carbonate and sodium chloride), may be extracted from the Solvay process cycle to be dried as “crude” bicarbonate product made without purification, by […]

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 […]
