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 furanes (< 0.1 ng TE/m³).
The advantages of the Vinnolit process can be summarized as follows:
- Recovery of hydrogen chloride from the by-products
- Optimum utilisation of the input chlorine to produce VCM
- Utilization of the energy content of the by-products in the form of steam
- Use of proven technology and materials
- Environment-friendly process
