PRESENTATION ON:-SODIUM BICARBONATE

PREPARE BY SHOAIB ABID

AZAM SIDDIQUI

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

SODIUM CARBONATE CARBON DI OXIDE ( ) WATER

RAW MATERIAL

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.
