Plasma Gasification
 
   

The Process

     
 
 
Feedstock Processing
Feedstock is delivered to the plant, weighed and unloaded in a covered storage area.
Feedstock (particularly for MSW) may be separated and sorted, with recyclables and inert material removed.
Feedstock is then processed, conditioned and sized to form Refuse Derived Fuel (RDF).
   
 
Thermal Conversion via Plasma Gasification
The Refuse Derived Fuel (RDF) is fed to the Plasma Gasification reactor with additives (to enhance the production of vitrified glass where applicable) at a rate to achieve a consistent overall feed composition.
Inside the Plasma Gasification reactor, which is operating in a high temperature and oxygen starved environment, the organic molecules dissociate to form an energy rich Synthesis gas.
Inorganic materials are melted into a molten slag and subsequently discharged from the reactor vessel. Upon cooling the slag is vitrified into an obsidian-like non-leachable inert material, which can be used, for example, as construction aggregate or to manufacture tiles or insulation materials.
   

 
Hot gas processing
The hot synthesis gas with other trace gases exits the gasifier at 1200ºC.
The hot Synthesis gas undergoes several process steps of cooling, filtration, scrubbing, drying before it is utilized for energy production such as power generation.
   
 
Power Generation and Export
The Plasma Gasification process transforms the latent chemical energy of the feedstock into Synthesis gas (Syngas) which is easily captured and used in a Power Generation plant to produce electrical power (depending on the power generation system used, additional efficiency can be extracted by integrating a flue-gas energy recovery system).
