Energy production that mitigates against dioxin formation

The nature of the process mitigates against dioxin formation, and prevents the pass through of pre-existing dioxins and related compounds.

For dioxins to be formed, much higher levels of oxygen are required, but in the Steing Gasification Process, any dioxin introduced to the feed is broken down during the pyrolysis stage.

Any chlorine in the feed, for example PVC plastic, breaks down under reducing conditions and is converted to hydrogen chloride (HCl) gas. HCl is highly soluble in water, and is removed and neutralised in the wet scrubbing process.

Acid components, such as sulphur, are removed with the gas and are extracted by the wet scrubber during the ph correction process.

Heavy metals and volatile metals such as lead, mercury, antimony and bismuth that have significant vapour pressure at the pyrolysis temperature will be reduced to metallic form and will be trapped in the gas scrubber, appearing as a component of the sludge from the scrubber. The levels of these components in the feed are controlled to minimise the levels of solid treatment residue.

The reducing conditions in the retort and the high temperatures within it mean that the metals of concern are unlikely to partition to the char fraction. However, the char system is a WID compliant combustion process with all the features necessary to control emissions.

A system that produces no dioxins. The future of power lies in a system that produces low emissions, no dioxins and reuses the nations waste. Stein Gasification offerrs such a solution.
