Competitive Advantages of AST Plasma
Can handle all kinds of wastes
Waste can be mixed or comingled
Handle large items without pre-processing
Can handle wet waste
Extruder optimizes syngas chemistry by homogenizing feedstock density.
➨ Analysis of Competitive Processes – Feed System
No need for air or co-reactants in process
High energy efficiency – significantly less energy loss than in other processes
AC electrodes in “brush arc model” so arc does not impinge on refractory
Generate high power levels – easily 100MW.
➨ Analysis of Competitive Processes – Furnace
Lower capital cost – equipment is streamlined design
Lower cost from having single power supply and single stage reactor
Lower operating costs – graphite electrodes are inexpensive to operate
Single vessel and no co-reactants or nitrogen all make for very compact footprint
Large throughput as AST process designed for large applications.
➨ Analysis of Competitive Processes – Finance
No dioxins or furans in syngas
Most chemically pure syngas of all processes
Automated tapping of slag and metals
High quality slag for making rock wool
Metals sold as billets to steel industry (can be high quality)
No combustion, no char, no ash.
➨ Analysis of Competitive Processes – Outputs
Vessel can operate for long-time without maintenance and no downtime
Continuous operation with automated electrode feed
No furnace shutdown required.
