Plasma-Based Emission/Pollution Control System

This technology uses cold plasma to break down pollutant chemicals as they are emitted, converting them into benign compounds. The cold plasma uses high-voltage electrical discharge to create ionized gas that interacts with pollutants in turbine exhaust. It breaks down nitrous oxides into nitrogen and oxygen or converts it into nitric acid. It oxidizes...
