By-Product Recovery Process
In the Vinnolit process, the liquid and gaseous wastes are completely incinerated at approx. 1150 °C.
The heat of the hot combustion gases is exploited to generate steam and the hydrogen chloride is recovered as a valuable feedstock which is returned in gaseous state to the oxychlorination process. Alternatively, aqueous HCl of 25 to 30% can be produced.
The treated waste gas complies with all applicable German statutory regulations, including those concerning the concentration of dioxins
and furans (< 0.1 ng TE/m³).
