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). |
