Transcript of SODIUM BICARBONATE
ON COMMERICAL SCALE, IT IS PREPARED BY PASSING CARBON DI OXIDE
GASTHROUGH THE SATURATED
SOLUTION OF SODA ASH
MANUFACTURING OF SODIUM BI CARBONATE
Sodium bicarbonate is a solid component .It is found crystalline and Powder form.Its commercial name is “BAKING SODA” It Decomposes on heating.
INTRODUCTION
THIS IS CHEMICAL COMPOUND. ITS COMMERICAL NAME IS WASHING SODA.
MELTING POINT :
IT DO NOT DECOMPOSE DUE TO TEMPERATURE .
THIS IS AVAILABLE IN MARKET AS LIGHT SODA & DENSE SODA ASH )
SODIUM CARBONATE
(CO2) is a chemical compound . It is a gas at room temperature. It is made of one carbon and two oxygen atoms.
. People and animals release carbon dioxide when they breath out.
Also, every time something organic is burnt (or a fire is made), it makes carbon dioxide.
Plants use carbon dioxide to make food. is the solid state of CO2 gas below (-78.5 °C)
CARBON DIOXIDE (CO2)
Water is a simple Triatomic molecule. The consist of 2 item hydrogen & 1 item is oxygen. The amount of water on the earth 1.35 million 97% of water consist of sea water. Sources of water is• Surface water• Underground water

In this section is mixed with water to prepare the saturation soda ash solution .This saturated solution of soda ash is now transferred to the next section of carbonation section
PREPARATION OF SATURATED SODA ASH SOLUTIOL
In this section, there is long tower similarly to the carbonating tower in soda ash perpartion.in this section the saturated soda ash treated with the compressed gas.
Soda ash introduced from the top of carbonating tower and from the bottom.
Reaction takes place forming Temperature is controlled at 40. Here, Reaction is
CARBONATION OF SATURATED SODA ASH SOLUTIOL
In This section is separated from the With the help oh Rotary Drum Filter .
The wet is now transferred the drying section
FILTRATION OF ()
In this section wet is first passed through the centrifuge to remove the lot of water and then dried in dryer at to get dry
It is 99.9% for drying continuous belt conveyor “OR” tube dryer is used.
DRYING
Sodium bi carbonate is mainly used in the following industries.
Drugs & Medical Leather Food product Baking powder Etc.
USES
