Climate protection in recycling of waste, transformation into new products.

No CO2 and NOX emissions from pyrolysis system

 

We protect our planet and waters, our oceans

 

 

 

 

Renewable energy production is a very good business opportunity for businesses,

Extra profit, because we don't have to pay for the waste and we also get money for its collection

 

 

    

 

 

Recycling waste is a safe business venture, there is more and more waste, more and more people live on our planet, and we produce more and more waste. Energy from waste is a growing business, the money is in the streets, you just have to bend for it. Your business can get bigger and bigger with a small investmen. Our goal is the local utilization of the waste generated in the community, with local labor, local job creation, to supply local people, because well as those in the Latin and Tribal regions of the Western Hemisphere, are not adequately served in terms of efficiently utilizing community and agricultural waste or in accessing reliable power sources.

MSW, RDF, plastic, tire, etc. distillation and gasification in water vapor microwave plasma

 

Water vapor plasma consists exclusively of hydrogen and oxygen; both components are active reagents that participate in oxidation-reduction reactions. There is no ballast, such as air plasma nitrogen, where its percentage is 78%. When reacting with chlorine-containing substances, water vapor plasma does not produce dioxin, which is one of the most toxic substances. The flue gases produced during the gasification of the steam plasma do not contain nitrogen oxides.

 

The main advantage of steam plasma reactors is that there is no nitrogen in the steam plasma, the plasma reactor, the gasifier and the plasma afterburner chamber, so there is no nitrogen dioxide (NO2) and nitrogen oxides (NOx). The hydrogen introduced into the reaction space with the steam plasma slows down the reactions of gaseous sulphur, phosphorus and free chlorine formation, i.e. gases that are difficult to remove in the gas purification unit.

Reactor production in the picture

 

 

 

 

Microwave plasma for ionization and thermal decomposition of product gases and flue gases

 

A "plasma filter" is a special reactor in which the plasma-forming gas is actually synthesis gas, which, when ionized, forms a high-temperature field (1500-4000 °C) that effectively breaks down all complex compounds (resins, aromatic molecules, tars, etc.). Our technology is based on the basic properties of microwave plasma, which enable the very effective effect of breaking down their gaseous components. The use of microwave plasma makes it possible to reach an average operating temperature of around 2500 0C. In this case, the heating rate of the various materials in the reactor is 100-1000 °C/s. Parallel to the effect of high temperature, the powerful ionizing effect of the microwave plasma in the reactor volume leads to the complete decomposition of the complex molecules of carbon-containing substances into the simplest molecules and ions.

 

Electric energy from organic waste

 

Our syngas generator® that produces fuel for the gas engine power generator. A very important aspect at gasification, only pyrolyzed carbon - from RDF / plastic / tire / etc. - can be gasified to a quality suitable for a gas engine. Filter out the tar from the synthesis gas with the resulting pyrolytic carbon, then gasify the tarry pyrolytic coal. The tar produced during the refining of pyrolytic oil can be gasified to produce electricit, very importante because it is very important to know that the tar left over from the refining is 60% of the pyrolytic oil, this is a big loss of energy, so this must also be used for electricity!

 

Syngas calorific value option selection

 

  • From air oxygen, when the calorific value of the produced syngas is 5-6 MJ/Nm3 (since the nitrogen content of the air is 78%, which reduces the calorific value of syngas)
  • With a water vapor plasma torch, when the heating value of the produced syngas is 25-30 MJ/Nm3 (water vapor plasma consists exclusively of hydrogen and oxygen; both components are active reagents that participate in oxidation-reduction reactions. There is no ballast, such as air plasma nitrogen, where its percentage is 78%)

 

New design / built gas generator that produces synthesis gas,

 

from RDF (Refuse Derived Fuel ) and waste tire, waste plastic, etc. pyrolytic coke with oxygen and hydrogen from water vapor plasma for GENSET There is no need for a gas tank in the system, the gas quantity is regulated by the gas quantity demand of the gas engine (engine suction). Gas production stops when the gas engine stops. Syngas production starts when the gas engine is started, continuous electricity production takes place after 15 minutes

 

 

  

 

 

Our carbonization and distillation technology…

 

The breakdown of the heat in the material (components) of our organic waste takes place in an oxygen-free atmosphere, which is environmentally friendly technology, because it is not incineration, but dry distillation in an oxygen-free vacuum space at temperature. 200℃ to 700℃. With our process, the status of waste ceases, and the material of is transformed into many products, such as e.g. diesel, gasoline, heating oil, clean coal, etc.

 

The resulting product gas and the diesel separated in the fractionated condensate can be used directly as fuel in electricity production. The vapors are also condensed into diesel oil suitable for diesel engine fuel, while the resulting gases are used as gas engine fuel and electricity is generated by the electric generators they drive.

 

It can be produced from waste by pyrolysis in an oxygen-free space

 

a)      pure coal (grill coke) for baking and cooking,

b)     oil for the heating and diesel for the car engine

c)      diesel or syngas fuel for electricity generation

 

Plasma chemistry

 

When an electromagnetic wave propagates in the plasma, certain reactions occur between the particles.

 

The main types of reactions are:

 

  1. Elastic collision and inelastic collision: such reactions lead to an exchange of energy between particles; the difference between them is that the elastic collision only leads to the transfer of kinetic energy between the colliding particles, but does not change the internal energy
  2.  Excitation and ionization: such reactions result in an increase in the number of free electrons or a change in the energy level of the atom.
  3. Charge transfer: this type of reaction results in an equivalent charge transfer between the particles. This kind of reaction mainly takes place in the collision process of ions and neutral particles.
  4. Charge recombination: it has two forms - diffusion and recombination. Diffusion is the process by which a charged particle reaches the wall and electrode to disappear. Recombination is a process in which positive ions capture a free electron and combine with electrons or negative ions to form new neutral atoms.

Microwave water steam plasma torch

 

High-power pure steam torch plasma operated by a 915 MHz microwave and its temperature measurements. Steam from a steam generator enters the discharge tube as a swirl gas at a temperature of ~140 °C. This steam becomes a plasma forming gas and produces a stable steam torch plasma. The torch volume is almost linearly proportional to the microwave power. The temperature of the torch flame was measured with an optical spectroscopy, analyzing the optical emissions of hydroxyl molecules ~309 nm.  The maximum temperature in a microwave-driven region was measured to be ~6720 °K

Microwave in the carbonisation – gasification in the non-thermal plasma

 

  • The non-thermal plasma its fundamental nature is that the temperature of the electrons is much higher than the temperature of the gas, including the vibrational and rotational temperature of the molecules. MW alone can reduce the amount of NOx and SOx in the flue gas by 99% and 85%, respectively. Plasmas contain reactive substances, especially ions, radicals or other oxidizing compounds, which can break down polluting molecules, organic particles or soot.

 

  • The electron consumes energy in ionization, excitation and dissociation of molecules and finally in the formation of active free radicals such as OH, O, N and H. These radicals oxidize SO2 and NO to SO3 and NO2, which then react with the water vapor H2SO4 and HNO3 present in the flue gas, and break the VOC bonds, promoting their formation and conversion to CO and CO2

 

  • The atmospheric plasma source is based on a specially designed microwave cavity. Microwaves at a frequency of 1 GHz - 5 GHz are fed into the plasma source, resulting in a high field concentration in the center of the cavity. It is excellent for the removal of highly polluted air pollutants such as volatile organic compounds (VOCs) and their fluorine-containing derivatives (FOCs), the synthesis of special gases and the production of nanoparticles. Microwave radiation is not generated by electrons, but by magnetrons.

 

  • When this radiation comes in contact with carbonic material it unleashes such large quantity of energy that a plasma field is generated. Due to this reaction, the incoming solid material and saturated steam go through a phase transformation that forces the carbon, oxygen and hydrogen molecules to break loose. Once these molecules leave the plasma field they attach to each other forming a new molecular structure, called syngas. 

 

 

Environmental protection in flue gas treatment

 

Our method of filtering flue gas for quality according to EU 2000/76 / EC directives

 

By means of flue gas filtering, the small power plant is inexhaustible for the renewable - with more and more raw materials annually. For the production of electrical and thermal energy from wastes, it is necessary to filter the flue gas produced during the combustion process from the combustion, which is ensured by the ceramic filters and by injecting the adsorbents in front of the filters to the pollutant content according to the EU 2000/76 / EC directives, to the air quality. Emissions from flue gas are below the permissible air emission limits provided by the ceramic filter. The flue gas is filtered with ceramic filters by adding adsorbents. The emitted flue gas component is continuously monitored by the analyzer, the measurement results are documented by continuous data recording.

 

 

 

 

Description of the catalytic conversion of foam ceramic filter elements by calcination

 

Raschig foam ceramic, which Ni, Cu, Mn, Pt, etc. can be made catalytic with metals, e.g. with the following procedure for Ni

 

We use nickel nitrate hexahydrate (Ni [NO3 ]2, 6H2O), AR - grade and calcium nitrate (Ca [NO3 ]2, 4H2 O), AR - grade. Precursors for the preparation of solutions in three different mass ratios 1: 5, 2: 5 and 4: 5. Then, the large-surface ceramic ring carriers are soaked in precursor solutions in a hot pool at 70 °C, and then the gel solution is dried. The wet impregnated and then dried Raschig ceramics were heated in the oven at 110 °C for 24 hours and then calcined at 950 °C for 6 hours. The calcined Raschig catalyzed finished ceramic is stored at room temperature in a closed container next to silica gel.

 

 

 

We offer technology to waste managers

 

Extraction of non-ferrous metals and precious metals from electronic waste

 

  • Electronic waste, PCB, plastic waste with metal, etc. which it is only possible to safely smelt the non-ferrous metal - precious metal content after carburizing. The resulting non-ferrous metal - precious metal alloy can be decomposed into its highly pure 99.99% alloying metals (gold, palladium, silver, copper, aluminium, tin, lead, etc.) in a self-sustaining way in terms of electricity and heat (gas, coke and the so-called pyrolytic oil obtained from energy carriers) in emissions within the limits of environmental protection.

 

 

  • Carbonization prior to smelting facilitates environmental approval in terms of emission limits, because during carbonization, we filter out the polluting components in the organic and inorganic condensate / condensate that would have gone out the smelter's chimney without carbonization. (filtering with condensate is used as a pre-filter for the flue gas)

 

  

 

 

Tire waste heat energy for heating

 

 

·        In the gasification space, e.g. the tire is pyrolytically broken down into hydrogen and carbon monoxide gases. Here, we maintain an oxygen-poor environment in the primary reaction space. CO2 is reduced to CO in the glowing carbon layer, where most of the sulfur in the reducing glowing carbon layer reacts with the steel wires of the tire above 900℃, where iron (III) sulfide (Fe2S3) is first formed, and then immediately iron (II) is reduced to sulfide. The complete oxidation takes place in the fire chamber at a temperature of 1300℃, with the oxygen of the secondary air mixed with the synthetic gas produced in the gasification chamber. The adjustment of the air-oxygen ratio is controlled by an automatic λ-probe (oxygen sensor) in order to maintain perfect combustion. In the absorber attached to the boiler, the remaining sulfur content is captured as salable gypsum (CaSO4). An aqueous solution of urea (urethane) is injected into the firebox to reduce NOx.

 

·        Material balance, e.g. The amount of rubber chips required for 100kWth heat output is 15kg/hour, its calorific value is 34 MJ/kg. The amount of slag produced is 3.5kg/hour, its composition is 2kg/hour of mineral matter and ~1.5kg/hour of spent steel wire. The slag can be taken out from the afterburner part, and the steel wire from the upper gasification part once a day. The slag can be disposed of, and the steel wire, free of rubber, can be delivered to smelting as useful iron. The concentrations of the components of harmful substances in the outgoing flue gas comply with EU directives 2000/76/EC, and are significantly below the permissible upper limit.

 

 

Heat pipes are superconductors of heat conduction

Their thermal conductivity is 1000 times higher than e.g. for solid copper conductors of the same size.

 

Characteristics of the "superconducting heat exchanger"

 

• Its operation does not require electricity, so no connection

• Its unclaimed, heat-transmitting metal surface was kept metal clean by ionic separation

• Its lifespan is endless, as there are no aging plastic, moving or wearing parts

 

 

 

 

Electricity from waste heat

Our machine resource for electric power generation…

 

  • The centrepiece of a waste heat power plant is the swing piston-driven vapour expansion engine (the swing piston expander), which was developed by ourselves, and is manufactured. The swing piston-driven expansion engines achieve an exceptionally high pressure difference, resulting in a much steeper enthalpy gradient and consequently much more electricity is generated compared to related technologies.

 

  • Another considerable advantage of the swing piston-driven expansion engines lies in its impressive partial load capability. The novelty of our system is the use of a motorized "hot air engine" driving the electric generator as a resource expander. The external combustion heat engine is an external heat engine with reciprocating crankshaft mechanism.

 

  • Operating temperature 100°C   600°C  on  10 bar – 60bar  amd expansion ratio 1:10 → 1:40
