Gasification Process

1
Gasification Process

• High Temperature Conversion of Wastes

A High Temperature Melting Gasification Process
2
The process
Based on the economic cycle of material, the
waste treatment installations must respect the
following principles

• Reduction of volume and mass of the waste
• Elimination of potentially dangerous elements
• Energetic valorisation and material recycling

3
Elimination of wastes by their valorisation
The process
Classical processes

• Disposal of wastes
• Conventional incineration and treatment of
  subsequent generated products
• Process with partial valorisation of the material
  contained in the wastes

The reactor with high temperature fusion

• Elimination of wastes by optimal valorisation of
  material and contained energy
• Simultaneous valorisation of energy and generated
  material
• The only material potentially containing damaging
  elements the concentrations of components coming
  from the washing of the gases are by far below
  the 5 level

The process
Pilot Testing Station
Germany

• Flow of 1.500 kg/h or equally max. 10.000 t/y
• Result of an industrial study
• Proven technology and tested successfully in
  industrial configuration
• The concept covers the industrial needs for flows
  in a range between 5.000 to 100.000 t/y

The process
No particular quality criteria are needed to the
waste (reduction, water content)No separation is
needed
waste
Mechanical and biological preparation of the
waste (dry stabilisation)
- Fuel based on waste - Mechanical preparation of
the wastes (rubbish, tyres) - Waste of commercial
and industrial origin - Special waste (medical,
biological, )
Additive material
- additives in function of the fuel type for
control of the reaction phases, e.g. limestone,
coke or used tyres.

The process
Feeding

• Material feeding with automatic operating
  equipments
• Controlled through fill-out checking
• Sorting out not required, minimum pre-treatment
• Metals and mineral substances mixing is desirable
• Water content up to 30 without problem (60-80
  possible)
• Process parameters optimisation through additives
  (coke, limestone)

The feeding

The process
Process of pyrolisis(chemical decompositions
under high temperature)
The reactor

• No combustion and hence no subsequent undesired
  products such as ashes, smoke or impure mixtures
  of ashes and smokes
• Higher efficiency of the gasification (75 80 )

Process

• Introduction of all the gases in the higher
  temperature zones
• Thermal transformation of the pyrolisis gas and
  of the products under 2000 C and added oxygen
• reduction of combustion products decomposition
  into their basic materials (CO, CO2, H2, H2O)
• Gas aspiration and conditioning into usable
  combustion gas

The reactor
11
The process
Combustion gas

• Extraction out of organic substances
• Energy vectors of high value in a synthetic
  quality (CO, H2)
• Min. 2,3 kWh of energy recovery per average kg of
  household waste
• Usage in mechanical and thermal energy

Slag

• Extraction out of mineral substances
• Completely vitrified and hence almost completely
  free of heavy metals
• Possible usage as construction material such as
  dams and ballast

Metal alloys

• Extraction out of metallic substances and heavy
• metals
• Mixture of melted metals
• Usage in the metallurgy for steel production

The products

Success factors
The process
Environmental impact

• High yield factor of the process
• Almost complete valorisation of the waste with
  minimal residue
• Products with respect of the environment I.e.
  Good conditions for authorisations and positive
  acceptance by the population

Costs

• Lower investment costs than with conventional
  processes
• Lower operational costs in combination with lower
  nominal capacities

Capacities

• Can be variable due to reactors in cascade I.e
  lower economical risks

Choice of operational site

• Multiple possibilities for instalment (in
  agglomeration, industrial or commercial zone)
• Simple integration into existing structure

Advantages for the customer

• Reducing the tendency of  widespread  of wastes
  due to limitations of disposal capacities
• Valorisation of energy produced via European
  legislation on renewable energy
• The obligation to fulfil standards and
  legislation that are highly demanding in terms of
  environmental protection

13
Factors for creating value
Operation of the installation generates the
following values

• Valorisation of waste(households, commercial and
  industrial waste, special waste, various
  residue)
• Valorisation of gas of synthesis(production of
  Methanol and energy)
• Valorisation of heat(district heating or steam
  distribution network)
• Valorisation of metals(conditioning of melted
  metals for metal production)
• Valorisation of slag(conditioning of
  sub-products such as granulates for filling
  material)
