Industrial Production of MgSo4,CaSo4, Mg(OH)² & MgCo³ & Na²Sio³

1)  Industrial production of MgSo4,CaSo4, Mg(OH)²

> Reaction
                                   
1)  Mgcl² + Ca(OH)²  ----->  Mg(OH)² +                                                            CaCl²

2)  Cacl² + H²So4  ------>  CaSo4 + 2HCL

3)  MgCl² + H²So4 ------> MgSo4 + 2HCL

> Process

 - In the industrial production of MgSo4 & CaSo4 first of all mixed salt bittern is first taken in a reactor.

- Ca( OH)² from line treatment tank is also charge into the reactor.

- Due to reactor precipitation of the Mg(OH)² is obtained.

- filter the mass in filter press to remove precipitation of Mg(OH)² which is dry pulverised & packed.

- Filtrate is further taken in a treatment tank when it is treatted with H²So4 .

- Dut to reaction with H²So4 in MgSo4 CaSo4 salt are formed.

- Now heat the solution to get CaSo4 which filter & remaining filtrate is further taken in chilling tank, when temperature is down to almost 10°C , so crystal of MgSo4 is obatin.

>  Uses
Use Of MgSo4 ( Magnesium Sulfate)

1]  They are used in madical,agriculture, food, preparation, chemistry, marine etc....

2]  Magnesium sulfate heptahydrate is also used to maintain the magnesium conc. in marine aquari which contain large amounts of stony corals as slowly depleted in their calcification process.

3]  In a magnesium deficient of stabilize of ions

Used of the CaSo4 (Calcium sulfate)

1] The main used of calcium sulfate is to product plaster of paris & stucco.

Used Of Mg(OH)² ( magnesium hydroxide)

1]  There are used in precusor to Mgo, health meltabolism, milk of magnesia, waste water treatment etc....



2) Industrial production of MgCo³

> Reaction

Mgcl² + Na²Co³  -----> Mgco³ + 2 Nacl

> Process

- Magnesium carbonet is basically produce by reation of sea bittern & sodium carbonet.

- first of all sea bettern which basically contain mgcl² is taken in jacketed reactor.

- Here heating provided by steam.

- Now charge paste of Na²Co³ in warm bittern solution till. precipitation due to reaction between the sea bittern & Na²co³ precipitation I of Mgco³ obtain.

- Filter the all mass in filter press & than give wash of water to remove chloride.

- Afret filtration & washing mass is taken in dryer & dry above 110°C

- Dry mass is pulverised to get desired find powder which is stored in polythene bag or suitable container

>  Uses

1]   The primary use of magnesium carbonate is the production of magnesium oxide by calcining magnesite & dolomite minerals are produce refrado brick.


3)  Industrial Production Of Na²Sio³

Sodium ailicate  is produced from sodium carbonate( Na²Co³) & silica

- In the industrial production first of all sodium carbonate & silica is taken in to fusion kettle here littel amont of water is added.

- Now in the kettle mixture is fused to 1400°C & then after fusion mass in taken the cooling chamber, where it is cool down slowly.

- There fore clear light bluish green crystal fromed sodium silicate is obtain.

- if the material is to be sold in from of the solution of the product dissolve in water.

  >  Used

1] In 1990 4M tons of alkali meral silicate were produced.

2] The main application  were in detergent,  pepar, water treatment & construction materials.

3]  Sodium silicate is frequently used in drilling fluids to stabilize  borehole wells & to avoid the collapse of bore walls.
