• Due to rapid change in technology, the correct
  design of all steps of the process last
  application of Cold Plasma Technology, VVX can
  offer a complete plant ECO-FRIENDLY and Energy
  saving, totally powered with green energy, so the
  final Production cost is low.

INTRODUCTORY REPORT The Nitric Acid can be
produced by 3 ways 1- Starting by Sodium
Nitrate (Chile Nitrate) that is a natural
mineral. 2- Starting from Air. Birkeland-Eyde
process. 3- Starting from Ammonia. Ostwald
process followings. (Currently used in
manufacturing) The 1 and 2 method have been
abandoned for a lot of reasons.

• PRESENT
• The Available Technique is considered the
  OSTWALD process and its variants.
• At the moment all plants for the production of
  nitric acid are currently based on the same basic
  chemical operations, developed on original
  process called OSTWALD, which includes
• Oxidation of ammonia with air to give nitric
  oxide.
• Oxidation of the nitric oxide to nitrogen
  dioxide and absorption in water to give a
  solution of nitric acid.

7

• The first step reaction is carried out at low
  pressure whereas the second step is at high
  pressure. These considerations, combined with
  economic reasons give rise to two types of nitric
  acid plant, Single pressure plants and Dual
  pressure plants.

8

• In the single pressure plant, the oxidation and
  absorption steps take place at the same pressure.
  In dual pressure plants absorption takes place at
  a higher pressure than the oxidation stage.
• The oxidation and absorption steps can be
  classified as-
• Low pressure (pressure below 1.7bar)
• Medium pressure (pressure between 1.7 and
  6.5bar)
• High pressure (pressure between 6.5 and 13bar)

9

• The main unit operations involved in the nitric
  acid process is same for all types of plant and
  in sequential order these are-
• Air filtration.
• Air compression.
• Air/ammonia mixing.
• Air/ammonia oxidation over catalytic gauzes.
• Energy recovery by steam generation and/or
• gas re-heating, Gas cooling.

10

• Gas compression, energy recovery and cooling
  (dual pressure plants only).
• Absorption with the production of nitric acid.
• Waste gas (tail gas) heating.
• Energy recovery by expansion of the
• waste gas to atmosphere, in a gas turbine.

11

• The problems and disadvantages of this,
  OSTWALD process are
• The use of Ammonia as a raw material, that have a
  cost and is dangerous.
• Explosion risk in every step of line for
  formation of Ammonia explosive mix.
• Explosion risk in absorbing column for formation
  of Nitrous/Nitric explosive mix.

12

• Toxic risk for handling and storage of Ammonia.
• Liquid waste to treat from boiler and heat
  exchanger.
• Solid waste as salt from boiler, from condensing
  tower and catalyst.
• Gas emission as NOx between 200 to 3500 ppmv to
  treat.

13

• Precious catalyst loss (Platinum-Rhodium) around
  0.2 to 0.25 gm/ T of HNO3.
• High temperature in line, until 900 C.
• High pressure in line, until 13 Bar.
• High Power requirement for operation. Only some
  part of power partially generated by
  self-production.

14

• Produced acid to 40-60 in water. If need more
  concentrated acid is necessary a Final step with
  Sulphuric Acid.
• Use of equipments expensive and need for careful
  monitoring.

15

• OLD Plasma Technology Process
• The AIR have around 21 of Oxygen and 78 of
  Nitrogen plus a very little other gas as Carbon
  Dioxide and others.
• At the beginning of Year 1900 the production of
  nitric acid was also made with this process
  known as Birkeland-Eyde or arch, from oxygen and
  atmospheric nitrogen.

16

• This process has been abandoned for a
• number of reasons that did not meet the
• demand of the industry, including
• A Technological difficulty in past time to
• have the right components as pumps,
• spray nozzle, corrosion resistant
• materials and others.
• B High consumption of electricity
• operating cost.

17

• The New Plasma Technology process
• High Voltage Ionisation 
• 1) N2 2O2 ----------------gt 2NO2 gas
•                  
•                       Wet Reactor
• 2) 3NO2 H2O ---gt 2HNO3 NO 
• liquid gas
  (Untreated)
•     
• Recirculation with  High Voltage Ionisation   
  Cold Plasma

18

• 3) 2NO O2 -----------------------gt 2NO2  gas 
• Wet Reactor
• 4) 2NO2 2H20 ------------------gt 2HNO3    
• Final Product liquid
• The N2 gas added with O2 gas go in first step
  where cross a special  High Voltage  Reactor.
• In this reactor the N2 react with O2 to form
• NO NO2 NOx              (reaction 1)

19

• The Air is filtered to remove dust and other
  materials and blowers in the first step where air
  enters into a special VVXs Cold Plasma Reactor.
• In this reactor the N2 react with O2 to form
• NO NO2 NOx (reaction 1)

20

• The NOx cross a special wet reactor in which it
  is contacted with a diffuses fog water.
• The only NO2 in NOx react with water to form
  Nitric Acid (reactions 2).
• The partially unreacted NO return to Cold plasma
  reactor to complete the reaction into NO2 (
  reaction 1).

21

• The unreacted NO and the excess N2 goes to Waste
  Air Treatment Plant by second blowers.
• The Nitric Acid produced is drained as a liquid
  from wet reactor and go in some tanks for
  storage.
• The water need for reactions can be taken from
  river, lake or well and is treated to remove the
  pollutants.

22

• Finally this water cross a deionising plant to
  Osmosis or Resin before to go to fog nozzle
  inside the wet reactor.
• The Waste Air Treatment Plant is foresee to
  Biofilter, with special biomass preinoculated of
  bacteria.
• The waste air treated, rich only in Nitrogen
  gas, is unload in environment

23

• Advantage of VVXs process
• The start gas is simply to have is nitrogen
• oxygen from Air.
• The oxidizing reaction of the nitrogen is at
  ambient temp. press. Thank the utilization of
  Cold Plasma Technology.
• The synthesis reaction of nitric acid by NO2 is
  carried from low temp. press., until ambient
  temp. press.

24

• 4. Catalyst Not required.
• 5. Energy requirement can be self-
• produced with Solar Panel and Wind
• Turbine..
• 6. Only final product is conc. Acid and
• require special storage.
• 7. No need of high press. or high temp. vessels
  and piping.

25
8. No explosion risk. 9. Less risks of
chemical accidents. 10. No high corrosion in
piping, pumps, blowers and others
thanks the low Press. temp. 11. No cost for
raw chemicals energy. 12. No cost for
storage of raw chemicals. 13. Eco-friendly
