  • The treatment for DeNOx and DeSOx of exhausted fumes are very complex and require more step of treatments to assure the required performance.
  • We offer a SEMIDRY  process which

has secondary products Ammonium

Sulphate & Ammonium Nitrate

that are a very good fertilizers, which

can sell in market and from this

they can reduce the operative

cost of the plant.

Our process is based principally on reactions induced in COLD PLASMA Reactor, and not require very expensive catalyst & high temperature of the fumes.

Our process operate at fume temperature, pressure & do not require to heat or to cool the fumes.

The COLD PLASMA Reactor is equipped with our special Cold Plasma Generator which requires a very low power.
  • Inside the Cold Plasma Reactor Ammonia in water solution is dosed, so the reactions are in Cold Plasma:

1- 2NH3 + 2NO2 + H2O + 1/2O2 -->2NH4NO3 Ammonium Nitrate

2- 2NH3 + SO2 + H2O + 1/2O2 (NH4)2SO4 Ammonium Sulphate

The Nitrate and Sulphate products inside the Cold Plasma Reactor are separated from fumes with Cyclone and sent to tank.

To achieve the best performance, after the cyclone the fumes are sent into Wet scrubber with alkaline water, for better separation of particles from fumes.

portable fertliser making plant
  • Now, you can make your fertiliser at your Home.
  • Introducing  World First  Mini-fertiliser Plant for Production of calcium Nitrate  fertiliser for agricultural farms, farming communities,

co-operative societies and others.

  • Optional : Ammonium Nitrate can

be made by adding Ammonia 

Gas cylinder

RAW Material :

Calcium , sodium  richer  stones, Land Side Stones can

be  accepted  EXCEPT  High Contents  silica Stones.

The chemical reaction in Plasma Chamber and stones  is :


Plasma  liquid  + CaCO3   =  Ca(NO3)2   + CO2       + H2O

                                  solid           salt                 gas         liquid

This is salt reaction of Plasma with Calcium.

More land stone are based on CaCO3.

The limestone have CaCO3 > 70%

The white marble is CaCO3 > 90%

The gravel is CaCO3 based.

If the stone have < 50% as Calcium Carbonate + Silicium + Iron + Potassium + Sodium +.....+  So, final product is  a mixture of  Nitrate of Calcium + Iron + Potasium + Sodium +...+

This fertilizer is GOOD because it introduce lot of micronutrients that ABSOLUTELY NEED to crop !

Maxm. & Min. Size of stone recommended for use:  From 10 mm to 300 mm

The silicon based stones are NOT good to produce Calcium nitrate.

Portable, Can be used anywhere in the world.

Require  Low electricity , Can run on Solar Panel

Do NOT require to purchase the raw material ! Natural stones can be taken as RAW material , Eco-friendly !

AVAILABLE IMMEDIATELY for fertirrigation - should not be diluted further!

Ready  solution from 10% to 20% in water.


Maximum production (as dry): 20 kg / day, 40 kg / day and 100 kg / day.

With these quantity can be fertirrigated m2/day up to 2000 or up to 4000 or up to 10,000 m2/day of crops.

Easy & Ready to use.

Lightweight,  Easily transportable.

mcac modular city air cleaner
MCAC ( Modular CITY Air Cleaner )
  • Air Pollution control System which purifies the AIR.
  • The pollution in cities is due to

thin dusts & Vehicle exhaust

which causes increase

of the allergic phenomenon

in the people of whatever age.

In the industrialized areas the concentration also overcomes the permissible limits,

10- million of particles per cm3. While in clean areas they have been measured only 100 per cm3.

The greater presence of dusts, blocks the circulation of the Fresh Air  in the urban areas. All we have seen at least once a city surrounded by a strip of grey clouds in form of smog.

The nature has always its remedies. A  Little shower of Rain & lightning , clean 3,00,0000  litres air from the dust & contaminants


Another  is   Modular City AIR Cleaner  which guarantee the cleaning of Air at  maximum efficiency,  with the smaller use  of energy.   The use of solar   panels, make them completely electrically self-sufficient.

The installation of the model require for a small supply of water and a connection to the sewer. Various Models are available from 25 K to 1000 K Lit /m3 capacities.

It can reduce :

Total dust : 30% to 70% Metals : 40% to 90%

Ammonia : 35% to 65% Hydrocarbons : 20% to 50%

Carbon monoxide : 40% to 80% Nitrogen oxide 40% to 90%

  • Low operating cost.
  • Unattended auto operation
  • No Frequent  maintenance
plasma generator
  • The main effect of the high-voltage electric field and high frequency is the creation of a plasma generation at  ambient temperature and pressure and therefore commonly referred COLD  PLASMA.
  • This cold plasma is generated

in the air has at least four effects

on air.

  • Polarization of particles, catalysis

of reactions which are not commonly

obtainable at ambient conditions.

Sterilization of bacteria and viruses; aggregation of particles.

The outgoing air from the chamber of the cold plasma has a qualitative content of substances other than they had before, while the content remains essentially the same mass.
