Breakthrough
The breakthrough flows from being able to produce a clean syngas capable of being fed into a gas engine or turbine at a highly competitive cost while simultaneously vitrifying the ash residues in the plasma converter.
The syngas as well as the chars and ash are all fed directly into the plasma vessel (closely coupled up to the fluid bed gasifier) the former operating at well over 1,000 degrees Celsius. The carbon remaining in the soot, tar and char is converted into further syngas to maximise energy recovery.
- The Plasma treatment thermally ‘cracks’ the dirty syngas (from the gasifier) breaking up its complex molecular structure and reforming it into a much simpler structure resulting in a clean hydrogen rich fuel gas of consistent calorific value.
- The ash material from the gasifier is simultaneously melted and forms a molten slag in the plasma vessel which is then continuously tapped off and, as it cools, it sets into a granite like glassy slag material which is a dense, hard, environmentally stable material capable of being re-used as building aggregate. It can also be granulated in water as it cools to produce a more readily useable product.
- The volume reduction is very substantial with the volume of inert slag being around 200 times less than the volume of the original feedstock material.
Conventional combustion, gasification and pyrolysis processes produce significant quantities of one or more of bottom or grate ash, toxic fly ash, chars, tars and acetates which are hazardous and, whose disposal and transport is increasingly expensive. In contrast, the Gasplasma Process, with its minimal waste residues, therefore enjoys a significant cost and environmental advantage.
